Show HN: SurveyMoji – An easy way to get realtime feedback with a link/QR code https://ift.tt/20AbRBM
Show HN: SurveyMoji – An easy way to get realtime feedback with a link/QR code Hi HN - I've been working on this site on and off for awhile. It started out as a personal tool and fun thing to hack on in my spare time. I recently added some UI improvements and a landing page and thought maybe it would be nice for other people to use as well. The idea was to create the fastest/easiest way to share a link to collect realtime feedback from a person's phone during a presentation or video call. Would love to hear any feedback, especially on UI design as it is the first time I've tried to create something that has a modern SaaS look to it. Built with go/htmx/alpinejs https://surveymoji.com November 30, 2024 at 09:47AM
Show HN: Jinbase – Multi-model transactional embedded database https://ift.tt/1CNZ8G3
Show HN: Jinbase – Multi-model transactional embedded database Hi HN ! Alex here. I'm excited to show you Jinbase ( https://ift.tt/7AZGMkO ), my multi-model transactional embedded database. Almost a year ago, I introduced Paradict [1], my take on multi-format streaming serialization. Given its readability, the Paradict text format appears de facto as an interesting data format for config files. But using Paradict to manage config files would end up cluttering its programming interface and making it confusing for users who still have choices of alternative libraries (TOML, INI File, etc.) dedicated to config files. So I used Paradict as a dependency for KvF (Key-value file format) [2], a new project of mine that focuses on config files with sections. With its compact binary format, I thought Paradict would be an efficient dependency for a new project that would rely on I/O functions (such as Open, Read, Write, Seek, Tell and Close) to implement a minimalistic yet reliable persistence solution. But that was before I learned that "files are hard" [3]. SQLite with its transactions, BLOB data type and incremental I/O for BLOBs seemed like the right giant to stand on for my new project. Jinbase started small as a key-value store and ended up as a multi-model embedded database that pushes the boundaries of what we usually do with SQLite. The first transition to the second data model (the depot) happened when I realized that the key-value store was not well suited for cases where a unique identifier is supposed to be automatically generated for each new record, saving the user the burden of providing an identifier that could accidentally be subject to a collision and thus overwrite an existing record. After that, I implemented a search capability that accepts UID ranges for the depot store, timespans (records are automatically timestamped) for both the depot and key-value stores and GLOB patterns and number ranges for string and integer keys in the key-value store. The queue and stack data models emerged as solutions for use cases where records must be consumed in a specific order. A typical record would be retrieved and deleted from the database in a single transaction unit. Since SQLite is used as the storage engine, Jinbase supports the relational model de facto. For convenience, all tables related to Jinbase internals are prefixed with "jinbase_", making Jinbase a useful tool for opening legacy SQLite files to add new data models that will safely coexist with the ad hoc relational model. All four main data models (key-value, depot, queue, stack) support Paradict-compatible data types, such as dictionaries, strings, binary data, integers, datetimes, etc. Under the hood, when the user initiates a write operation, Jinbase serializes (except for binary data), chunks, and stores the data iteratively. A record can be accessed not only in bulk, but also with two levels of partial access granularity: the byte-level and the field-level. While SQLite's incremental I/O for BLOBs is designed to target an individual BLOB column in a row, Jinbase extends this so that for each record, incremental reads cover all chunks as if they were a single unified BLOB. For dictionary records only, Jinbase automatically creates and maintains a lightweight index consisting of pointers to root fields, which then allows extracting from an arbitrary record the contents of a field automatically deserialized before being returned. The most obvious use cases for Jinbase are storing user preferences, persisting session data before exit, order-based processing of data streams, exposing data for other processes, upgrading legacy SQLite files with new data models and bespoke data persistence solutions. Jinbase is written in Python, is available on PyPI and you can play with the examples on the README. Let me know what you think about this project.

The compiler also supports Linux, FreeBSD, macOS and Windows, on amd64 and arm64. This didn't require any changes to the compiler, just enabling it after setting up tests to validate that it already worked.

Show HN: It took me 5() months to build a Plausible alternative https://ift.tt/AUifEpX
Show HN: It took me 5() months to build a Plausible alternative After months of using Google Analytics I realized only about 50% of people accepted my cookie-popup. I had months of incorrect data for my website. I started looking for alternatives and eventually found Plausible, which is great (and open-source). Problem is, I didn't feel like paying 9$ a month to see the amount of visitors on a website i didn't even earn anything on, it was just a hobby project. Eventually I started making my own web analytics. Which actually isn't that hard. It took me about a month of working on my spare time every now and then. Being GDPR compliant basically means to not save any personal identifiers. At first I thought it would be easy since something like a public IP adress can't count as a personal identifier right? I was very wrong. How it works: When a user visited my website I saved the IP and Header for 24 hours. Then if they visited again I checked the combination of IP and Header against the ones saved in my DB. If they were the same I simply added 1 view to my data. If they weren't the same I added 1 unique daily user and 1 view. That's in short how it works. A few weeks later I realized if I had this problem then other would also have it. So I started working on Simplytics.dev. I had to do a lot of new stuff and re-build my code from the ground-up twice. Small things like OAuth was completely new to me and took up a lot of time. But eventually I got here and just launched something that with the knowledge I have today wouldn't even take a third of the time recreating today. It's my first real "Launch" and it feels really good finally creating something AND publishing it. Instead of a montly fee I opted to make it a pay-once service. Right now it's priced at 49$ but I'll see how it works out. If you got any questions on how it works Id love to answer them. November 25, 2024 at 07:35PM

Show HN: I built an extension to contact Airbnb hosts direcly https://ift.tt/dt1hOsy
Show HN: I built an extension to contact Airbnb hosts direcly Hey HN, Over the years, I’ve found myself frustrated with the extra fees Airbnb. While they provide a lot of convenience, the service fees often stack up to a point where they overshadow any potential savings. I started wondering if there was a way to connect directly with property hosts and skip the middleman entirely. That curiosity led me to build getaway.direct, a free Chrome extension that helps travelers save money. It works like this: 1. You browse listings on Airbnb. 2. The extension scans for direct booking links, host websites, or social media profiles where you can reach out to the host directly. 3. It shows those results instantly, so you can compare prices, avoid service fees, and book smarter. The main idea is to provide transparency. A lot of hosts already have their own websites but rely on platforms like Airbnb for visibility. This tool helps surface those direct options, which can often save you 10-20% per booking. I’d love to hear your thoughts: Would something like this be helpful to you? Also, I’m curious to get feedback on ways to improve the tool—whether it’s adding more integrations, improving usability, or something else entirely. Thanks for reading! Let me know what you think. https://ift.tt/3hywj2M November 29, 2024 at 03:18PM

Show HN: TeaTime – distributed book library powered by SQLite, IPFS and GitHub https://ift.tt/zQcyISR
Show HN: TeaTime – distributed book library powered by SQLite, IPFS and GitHub Recently there seem to be a surge in SQLite related projects. TeaTime is riding that wave... A couple of years ago I was intrigued by phiresky's post[0] about querying SQLite over HTTP. It made me think that if anyone can publish a database using GitHub Pages, I could probably build a frontend in which users can decide which database to query. TeaTime is like that - when you first visit it, you'll need to choose your database. Everyone can create additional databases[1]. TeaTime then queries it, and fetches files using an IPFS gateway (I'm looking into using Helia so that users are also contributing nodes in the network). Files are then rendered in the website itself. Everything is done in the browser - no users, no cookies, no tracking. LocalStorage and IndexedDB are used for saving your last readings, and your position in each file. Since TeaTime is a static site, it's super easy (and free) to deploy. GitHub repo tags are used for maintaining a list of public instances[2]. Note that a GitHub repository isn't mandatory for storing the SQLite files or the front end - it's only for the configuration file (config.json) of each database, and for listing instances. Both the instances themselves and the database files can be hosted on Netlify, Cloudflare Pages, your Raspberry Pi, or any other server that can host static files. I'm curious to see what other kinds of databases people can create, and what other types of files TeaTime could be used for.

Show HN: A website to practice for job interviews https://ift.tt/gWtUu9L
Show HN: A website to practice for job interviews A little backstory- When I first arrived in Canada as an international student, I met a guy who created a product called InterviewPal. I was fascinated and eager to use it, but soon discovered it was exclusive to University of Alberta students. This made me frustrated so I decided to take on the challenge of building a better alternative- something more accessible and affordable. After I announced Zilta’s waitlist on LinkedIn, Aryan blocked me, which bummed me out for a bit. But it only fueled my drive to create something much better than his overpriced product. My goal was to offer a solution that students and recent grads could actually afford and benefit from. And that’s how Zilta came into existance. I also wanted to give indie hacking a shot and took this endeavor so you can say I hit two birds with one stone haha --- Zilta was launched in June but I wasn't able to work on it extensively because of the workload from college and a part-time job I do. Now that the semester is approaching its end, I'm getting more time for it. Frankly speaking, I don't really know where to take this product to. Right now I am a little confused if I should focuss on marketing and getting more users to try it out and then add more features to it or the opposite. On the other hand, I've also listed this startup to sell for a few bucks because marketing is so hard. What I want deep down? I want this product to grow to 1-2K MRR and then sell it. The problem? I am not sure if I'm heading in the right direction. I'd like you all to give it a try and roast this product. I'm open to receving constructive critism and any advice that can help me succeed in this journey. Should I work on marketing, adding more features or selling this? https://www.zilta.io/ November 27, 2024 at 10:24PM

Show HN: Open-Source Pull Request AI Reviewer https://ift.tt/Fbw1Kyr
Show HN: Open-Source Pull Request AI Reviewer Hey HN, Over the last year, I’ve reviewed more than 1000 code changes. Most of the time was spent catching obvious mistakes rather than debating complex design decisions. If we estimate ~10 minutes per review, that’s 160+ hours spent reviewing code in just one year. So I thought: could I get some of that time back using LLMs? That's why I spent the last few weekends building Presubmit.ai, an open-source AI reviewer that runs as a Github Action right when you open a Pull Request. The results so far are promising: I estimate it can reduce the review time by 50%, which in my case would mean I save 80hours (~10 working days) per year. Unlike similar SaaS solutions, the goal is not to replace the human reviewer but to highlight obvious mistakes early, spot security vulnerabilities and give more context about the change. I like to think of it as a “pre-reviewer”. Some of its features are: * Line-by-line comments * PR summarization * Title generation on request * Responds to review comments It supports all major LLMs, but I’ve found Anthropic's Claude works best for this use case.

Show HN: VS Code extensions that display CGM blood glucose levels in status bar https://ift.tt/4XrD7SW
Show HN: VS Code extensions that display CGM blood glucose levels in status bar As a Type 1 diabetic, I need to continuously monitor my blood glucose levels. I’ve implemented a couple of Visual Studio Code extensions that retrieve the latest blood glucose readings from your CGM and display them in your VS Code status bar. One VS code extension uses the Nightscout CGM to retrieve the blood glucose readings. It requires users to run the Nightscout application on a hosted server. A nice benefit of Nightscout application is that it works with all the major CGM devices. However, a slight drawback of this option is that it requires a hosted third party software (Nightscout) for proper functionality. I’ve also implemented a Visual Studio code extension for those (like myself) that use the Freestyle Libre CGM. This version connects directly to LibreLinkUp to retrieve the latest blood glucose readings and display them in your VS code status bar. This removes the dependency for the intermediary Nightscout application. If you are or know any software engineers living with diabetes, these tools might be helpful with diabetes management. These are tools I built for myself that help me manage my diabetes. They are completely free and open source. I am not selling anything. Users of the tools can use them without any restrictions or connection to me. I am genuinely trying to help others in the community that are software engineers and might find this helpful. If you try out any of these extensions, I’d love to hear back from you. Any feedback on improvements are very welcome and appreciated. - https://ift.tt/DnZj7fG... - https://ift.tt/WdSLAFD...

Show HN: Bike route planner that follows almost only official bike trails Hey guys, I built a route planner that is mostly focused on bike touring and using existing bike infrastructure. For each request you're shown what bike tracks/trails your route uses and can further explore them by showing them on map or going to the official trail route. The main idea for the app is to have a friendly and easy to use planner that would make heavy use of official bike trails data (mainly from OpenStreetMap) and make it easy to plan a longer trip using the best possible bike routes out there. Currently the app only works for the Euro region but I'm planning to add North America very soon and then rest of the world. Technical overview: Route finding - Graphhopper sitting in a docker container on a Hetzner server somewhere in Germany. It has 38 GB of graph data(Europe) loaded into RAM for a fast graph traversal. Web App - Next.js 14 with Typescript, backend on the newest version of .NET Map tiles - right now I'm using MapTiler their free tier but planning to switch to my own home server soon and host the maps on it. https://trailimap.com/ November 21, 2024 at 12:23AM

Show HN: Autotab – Programmable AI browser for turning web tasks into APIs https://ift.tt/dh01w2N
Show HN: Autotab – Programmable AI browser for turning web tasks into APIs Hey HN, we're Alexi and Jonas the co-founders of Autotab ( https://autotab.com ). Autotab is a chrome-based browser you can teach to do complex tasks, with a simple API for running them from your app or backend. Here is a walkthrough of how it works: https://youtu.be/63co74JHy1k , and you can try it for free at https://autotab.com by downloading the app. Why a dedicated editor? The number one blocker we've found in building more flexible, agentic automations is performance quality BY FAR ( https://ift.tt/OoUy1rL... ). For all the talk of cost, latency, and safety, the fact is most people are still just struggling to get agents to work. The keys to solving reliability are better models, yes, but also intent specification. Even humans don't zero-shot these tasks from a prompt. They need to be shown how to perform them, and then refined with question-asking + feedback over time. It is also quite difficult to formulate complete requirements on the spot from memory. The editor makes it easy to build the specification up as you step through your workflow, while generating successful task trajectories for the model. This is the only way we've been able to get the reliability we need for production use cases. But why build a browser? Autotab started as a Chrome extension (with a Show HN post! https://ift.tt/DNzKPEW ). As we iterated with users, we realized that we needed to focus on creating the control surface for intent specification, and that being stuck in a chrome sidepanel wasn't going to work. We also knew that we needed a level of control for the model that we couldn't get without owning the browser. In Autotab, the browser becomes a canvas on which the user and the model are taking turns showing and explaining the task. Key features: 1. Self-healing automations that don't break when sites change 2. Dedicated authoring tool that builds memory for the model while defining steps for the automation 3. Control flows and deep configurability to keep automations on track, even when navigating complex reasoning tasks 4. Works with any website (no site-specific APIs needed) 5. Runs securely in the cloud or locally 6. Simple REST API + client libraries for Python, Node We'd love to get any early feedback from the HN community, ideas for where you'd like the product to go, or experiences in this space. We will be in the comments for the next few hours to respond! November 21, 2024 at 12:22AM

Arch is a uniquely intelligent infrastructure primitive, engineered with purpose-built fast LLMs [3] for tasks like intent detection over multi-turn, parameter identification and extraction, triggering single/multiple function calls, and offers convenience features to auto dispatch LLM calls for summarization based on data from your APIs via system prompts configured in archgw. Today, the approach to build a smart production-ready agent is weaving together a large set of mono-functional opinionated libraries, adding extra layers like LLM-based preprocessing to determine things like relevance and safety of the user's prompt (e.g. applying governance and guardrails). Once past that stage, developers must extract relevant information from the user prompt to determine intent, extract parameters as necessary, package relevant tools calls to an LLM to trigger a backend API to execute particular domain-specific task. etc. After all that is done then only are developers ready to trigger an LLM call for summarization and must manage upstream error handling and retry logic themselves. Not to mention, if they want to experiment with multiple LLMs or move between LLM versions, they have to write crufty undifferentiated code. This entire experience is slow, error prone, cumbersome, and not specifically unique. Prior to building archgw, the team spent time building Envoy [2] at Lyft, API Gateway at AWS, specialized search and intent models at Microsoft Research and worked on safety at Meta. archgw was born out of the belief that several rules based mono-functional tools should be converged into a multi-functional infrastructure primitive designed for prompts and agents. We built archgw on the highly popular, battle-tested open source proxy Envoy and re-imagined it for prompts and agents. For this we had to build blazing fast LLMs [3] that can handle crufty, ahead-in-the-request-path type of work in handling and processing prompts that are sent to an agent, so that developers can focus on what matters most: building fast personalized agents without the unnecessary prompt engineering and systems integration work needed to get there. Here are some additional details about the open source project. arghw is written in rust, and the request path has three main parts: * Listener subsystem which handles downstream (ingress) and upstream (egress) request processing. * Prompt handler subsystem. This is where archgw makes decisions on the safety of the incoming request via its prompt_guard primitive and identifies where to forward the conversation to via its prompt_target primitive. * Model serving subsystem is the interface that hosts all the lightweight LLMs engineered in archgw and offers a framework for things like hallucination detection of our these models We loved building this open source project, and our belief is that this infra primitive would help developers build faster, safer and more personalized agents without all the manual prompt engineering and systems integration work needed to get there. We hope to invite other developers to use and improve Arch. Please give it a shot and leave feedback here, or at our discord channel [4] Also here is a quick demo of the project in action [5]. You can check out our public docs here at [6]. Our models are also available here [7]. [1] https://ift.tt/wBqExKN [2] https://ift.tt/wVAeqRG [3] https://ift.tt/pkYzJmQ...

Show HN: Fireproof – local-first database with Git-like encrypted sync https://ift.tt/BgvmUqu
Show HN: Fireproof – local-first database with Git-like encrypted sync Hi, HN! As a cofounder of Couchbase, I pioneered mobile sync, and I’ve always wanted to bring the speed and reliability of local-first data to the web, incubating PouchDB among other efforts. I learned the constraints of real world financial applications at McKinsey & Company FinLab, and Merkle integrity research at Protocol Labs taught me smart contract data structures. As part of the JavaScript community (and early hosting provider for NPM) I’ve been waiting, and now with the availability of APIs like Passkeys and Origin Private Filesystem, I’m happy to say the browser is ready to support embedded databases. Front-ends are a lot easier to write when your database handles live sync for you, but the existing solutions rely on heavyweight cloud APIs instead of putting the smarts at the edge, where it belongs. I started from a different set of constraints, and arrived at a lightweight embedded database that uses a git-like data model to offer cryptographic causal consistency across browsers, edge functions, and anywhere TypeScript runs. It’s designed to make building full-featured apps as simple as calling `db.put({ hello: "world" })` and syncing them as easy as calling `connect(db, remote)`. People are using Fireproof for AI character chat[1], personal finance[2], and hedge funds[3], and we aim to be simple enough for novice coders to build enterprise-critical apps. Fireproof makes product owners dangerous, because just a little bit of code can define an application’s workflow and data model. See the code sample below. The reactive APIs[4] are designed for live collaboration so your user interfaces update automatically, making it an easy way to add query collaboration to legacy dashboards, or write new interactive tools for your team. Merkle CRDTs[5] provide multi-writer safety while maintaining tamperproof data provenance, conflict tracking, and deterministic merges. The storage engine writes content-addressed encrypted files that can be synced via commodity backends like S3 or Cloudflare[], without sacrificing data integrity. Our contributors include legends like Damien Katz, Meno Abels, Mikeal Rogers, and Alan Shaw. Fireproof is open source (Apache/MIT) and we know there are rough edges, so we hope this post stirs up collaborators![6] Please `npm install @fireproof/core` and give us feedback[7]. We are on the stable side of beta, so it’s a great time for the adventurous to join. I’m excited to see all the apps people write now that it’s easy!

Show HN: Remy – AI-Curated Video Playlists on Any Topic https://ift.tt/j8EolyB
Show HN: Remy – AI-Curated Video Playlists on Any Topic Hey HN, we recently launched Remy, an AI agent designed to take the pain out of video search, and wanted to give the HN community a technical deep dive on how it works under the hood. The Problem: There’s a ton of valuable content on the internet, but finding the “best parts” of long videos is frustratingly inefficient. Current video search methods haven’t evolved much since the early days of YouTube and aren’t designed for today’s massive volume and variety of information. Instead, we’re left scrubbing through long videos or, worse, missing valuable content entirely due to decision paralysis. Remy’s goal is to offer a smarter way to surface exactly what you’re looking for, in a fraction of the time. The Solution: In less than a minute, Remy delivers custom playlists that isolate the best video moments from across the internet. It finds, clips, and organises segments to get you exactly what you need — without the endless search and skip game. How it works: Remy is powered by a stack of LLMs (and some non-LLM magic) designed for fast, focused video search and transcript processing. Here’s the pipeline: 1. Request Analysis When you send a message, the system decides whether to provide an immediate response, search the web, or start assembling video clips. If video is the best option, Remy generates a playlist outline with concise titles and detailed descriptions tailored to your query. For temporal queries, Remy automatically adjusts context to absolute dates (e.g., “tomorrow’s NBA games” → “November 15th NBA Games”). 2. Content Retrieval Using a ‘wide net’ approach, Remy generates a large set of targeted queries and searches the web for videos that could match your needs. 3. Multi-Step Filtration & Processing Each video goes through: - Transcript Pull: Extracts YouTube transcripts. - Non-LLM Filter: Filters out low-quality or AI-generated content based on YouTube stats, creator channels, release date, and other parameters. - Punctuation Restoration (BERT): Restores punctuation for better LLM comprehension. - Clipping: Uses an LLM to locate and clip the most relevant segments of the transcript based on your request. - Evaluation: Uses an LLM to score clips on relevance, completeness, and interest level. Only the best make it to the final playlist. 4. Reordering & Overview A final LLM gets fed the top 16 clips for each topic, filters them down to the best 4 (at most), and arranges them for maximum uniqueness. Each section gets a brief overview, with added context pulled and cited from the web to give you additional context. The result? A playlist tailored to your exact query, delivered in under a minute, without unnecessary noise. We’d love to hear your thoughts and feedback. If there’s something you’re curious to try or any edge cases that it's not handling, let us know. And if you come across any bad clips, please use the report button to flag them!

Show HN: Jelly – A simpler shared inbox for small teams Hello HN! I wanted to share something we at Good Enough ( https://goodenough.us ) built over the past year: Jelly! https://letsjelly.com Jelly is a simpler shared inbox for small teams (like us) to answer team email. We had just been sharing a login to Fastmail previously, but as email started getting busier, that really started to stink as a solution — no one knew who was going to answer what, if someone else saw an email or not, etc etc. And a Google Group would prove to be worse, as replies too easily got lost to personal inboxes if someone accidentally didn’t “Reply All”. It wasn’t great! We went looking for a tool to solve these problems, but everything we found was way too much software, and really quite expensive charging per seat. We didn’t need a complex ticketing system. We just needed email, as a team, in a simple and sane way. So we built Jelly! And we’re not charging per seat, so you can bring your whole team for a very affordable price. (As a quick comparison for our team of six: Jelly’s lowest tier costs just $29/month while Zendesk’s costs upwards of $330/month.) We would love to hear thoughts from anyone on a small team that needs to handle shared email. Also, if you know of other teams in that same position, we’d appreciate you letting them know about Jelly. Thank you! https://letsjelly.com/ November 12, 2024 at 11:55PM

Show HN: SICP-VSCode https://ift.tt/YtoBnuW
Show HN: SICP-VSCode I am sharing an opinionated configuration for VS Code that should suffice to work through Structure and Interpretation of Computer Programs (SICP). I have owned SICP for a decade or more and am giving it another go. I (re)started it last weekend using the DrRacket editor, which is fine, but I spend most of my time in vs code. It was a jarring to use another editor. So, in an evening of delightful bikeshedding, I now have a setup that should let me work through SICP in vs code. I thought I'd share this in case someone else is interested or has any feedback. This is a barebones configuration with a lightly tested installation script that works on my machine! I wanted to avoid installing a bunch of vs code extensions and was able to get this working with only a single extension to add scheme support to vs code. Any feedback is welcome and I hope someone gets some use out of this! https://ift.tt/BnhLTZc November 9, 2024 at 08:27AM
Show HN: I build a FullStack boilerplate to ship my projects faster https://ift.tt/UXsMr4e
Show HN: I build a FullStack boilerplate to ship my projects faster Every time I start a new project, it’s the same drill: setting up authentication, routing, databases, UI, etc. Sound familiar? I wasted 10+ hours on the same repetative setup. So I built Getstart, a SaaS-ready framework with everything you need to go from zero to launch—fast. It’s all here: NextAuth for easy auth Prisma + MongoDB for scalable databases Next.js API routes pre-built Nodemailer for emails Razorpay for both domestic and international payments Tailwind and Shadcn for sleek and customizable UI Let me know what you guys think and what can be improved https://ift.tt/BlxtpF3 November 9, 2024 at 03:10AM
Show HN: RL Agent that can auto-optimize your LLM prompts https://ift.tt/YCU4P0T
Show HN: RL Agent that can auto-optimize your LLM prompts Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://ift.tt/2GREWyf... Check out our website too: https://ift.tt/5KET7Fp In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the agent selects an action to modify the current prompt based on the state representation, which encodes features of the prompt. The agent receives rewards based on a multi-metric evaluation of the model's responses, encouraging the development of prompts that elicit high-quality answers. And see our github repo! https://ift.tt/qIzUsV2 https://ift.tt/Q6uTSz0 November 9, 2024 at 12:17AM

Show HN: Samsar One Version One is now live https://ift.tt/IK9iYo0
Show HN: Samsar One Version One is now live Hi all, 6 months ago I started building out an app which combines all the SoTA gen-ai models out there into one platform which anyone could use to create 2-4 min long videos starting from scratch, starting from an idea. I received a ton of feedback from HN community & others along the way. Today excited to announce version one of app.samsar.one, a platform which allows anyone to easily and consistently create long, coherent and consistent generative-ai videos while picking and choosing their model starting from merely an idea. https://app.samsar.one/ October 31, 2024 at 02:06PM

Show HN: Krixik – Easily sequence small/specialized AI models (pip-installable) https://ift.tt/7YIkjGy
Show HN: Krixik – Easily sequence small/specialized AI models (pip-installable) Our initial intention was to experiment with a smartbook idea, but we couldn't find a good prototyping tool for small/specialized AI models. That rabbit hole took us through vector databases, through infra for small AI, and finally here. We’re particularly proud of the accessibility/simplicity of our code syntax. Krixik’s model library is limited to eleven model types (modules) and a few dozen models, but we will significantly expand it. Other enhancements, like a local client and several 3rd-party integrations, are also planned. You require API credentials to try Krixik. You can quickly get them through this form: https://ift.tt/f0Khbn3 And here’s a demo video (our YouTube channel also has a couple dozen example videos in it): https://youtu.be/WpSSYLfvfdM https://ift.tt/gcrE5tP November 4, 2024 at 07:03PM

Show HN: I made an interactive sentiment model comparison site https://ift.tt/9gcrL7j
Show HN: I made an interactive sentiment model comparison site Hey HN, I needed to assess the state of sentiment models and couldn’t find a good way to compare them. I built this interactive site that lets you compare 12 models side by side, from Python libraries like NLTK Vader, to top performing models on HuggingFace, to commercial sentiment APIs and GPT4o. This is a research project, there is no paywall - you can enter your own text (1) and get the results back immediately. The results are fascinating and we made it easy to explore not just the leaderboard, but where models get it wrong. For example, most models (including AWS Comprehend) can’t get this positive sentiment: "Food doesn’t get better than this. I was sad when I finished, actually sad. To die for." (2) And yes, GPT4o is currently the best performing. It's crazy how many laboriously researched models are superseded by general purpose foundation models. Let me know what you think? 1: https://ift.tt/jVE76eM 2. https://ift.tt/1Cl7ReG... https://ift.tt/duJfKWQ November 1, 2024 at 11:49PM
