    Project mention: Ask HN: Tell us about your project that's not done yet but you want feedback on | | 2023-08-16

    This is very cool! I just downloaded the extension and tried a hello world program. Will tinker a bit more.

    If you can make a library to run python code inside a JS project (like Next JS) then we could build a code interpreter in Next JS. Would be super cool. Here is a python implementation - - for your reference.

    Project mention: Show HN: Stargazers Reloaded – LLM-Powered Analyses of Your GitHub Community | | 2023-09-30

    Hey friends!

    We have built an app for getting insights about your favorite GitHub community using large language models.

    The app uses LLMs to analyze the GitHub profiles of users who have starred the repository, capturing key details like the topics they are interested in. It takes screenshots of the stargazer's GitHub webpage, extracts text using an OCR model, and extracts insights embedded in the extracted text using LLMs.

    This app is inspired by the “original” Stargazers app written by Spencer Kimball (CEO of CockroachDB). While the original app exclusively used the GitHub API, this LLM-powered app built using EvaDB additionally extracts insights from unstructured data obtained from the stargazers’ webpages.

    Our analysis of the fast-growing GPT4All community showed that the majority of the stargazers are proficient in Python and JavaScript, and 43% of them are interested in Web Development. Web developers love open-source LLMs!

    We found that directly using GPT-4 to generate the “golden” table is super expensive — costing $60 to process the information of 1000 stargazers. To maintain accuracy while also reducing cost, we set up an LLM model cascade in a SQL query, running GPT-3.5 before GPT-4, that lowers the cost to $5.5 for analyzing 1000 GitHub stargazers.

    We’ve been working on this app for a month now and are excited to open source it today :)

  • agenta

    The all-in-one LLM developer platform: prompt management, evaluation, human feedback, and deployment all in one place.

    Project mention: Ask HN: How are you testing your LLM applications? | | 2024-02-06

    I am biased, but I would use a platform and not roll your own solution. You will tend to underestimate the depth of capabilities needed for an eval framework.

    Now for solutions, shameless plug here, we are building an open-source platform for experimenting and evaluating complex LLM apps ( We offer automatic evaluators as well as human annotation capabilities. Currently, we only provide testing before deployment, but we have plans to include post-production evaluations as well.

    Other tools I would look at in the space are promptfoo (also open-source, more dev oriented), humanloop (one of the most feature complete tools in the space, enterprise oriented), however more enterprise oriented / costly) and vellum (YC company, more focused towards product teams)

  • langchain-visualizer

    Visualization and debugging tool for LangChain workflows

    Project mention: GPT-3 will ignore tools when it disagrees with them | | 2023-03-06

    > Langchain actually doesn't make getting the full text of what's being sent to the LLM easy (or at least I couldn't find a good way to do it).

    I ran into the same problem, which is why I ended up building . Hopefully that is useful for you too :)
