<p>Hey HN, I’m Ben, and I’ve been tinkering with prompt-iteration tooling for about a year. My first idea [1] was an open-source tool that lets you try different variations of prompts, but even though I used it endlessly for the first 5-ish days, I… never used it again.<p>I wrote other scripts, compiled personal eval sets, and subscribed (then unsubscribed) to a bunch of online tools. Nothing seemed right.<p>Until last Friday when, talking about side project ideas with my girlfriend, she said, “What if it was in your code editor?”<p>And I thought, wow, I love this woman.<p>This VSCode extension instead lets you highlight your prompt text and run it against any and all models [2]. You can toss in your API keys, which are only stored locally, and use it for free.<p>Any feedback would be invaluable - this is my first extension!<p>I’ll be adding the same highlighting functionality I have for prompts to schema validation, where you can highlight any form of schema (pydantic, zod, json), and I’ll use a small llm to parse it + format it for different providers.<p>[1] <a href="https://github.com/benguz/prompt-octopus">https://github.com/benguz/prompt-octopus</a>

<p>Hey HN!<p>In my experiments with prompt engineering, I ran into a problem: most prompts I'm designing can't be quantitatively tested because they don't have a right/wrong answer (eg. providing essay feedback, deciphering corporate-speak in meeting minutes). That means I can't run evals, super powerful tools like ChainForge[1] are too high-overhead, and running one prompt at a time in ChatGPT... sucks.<p>I built Prompt Octopus[2] to evaluate as many prompts as I want, side by side, and it's sped up my workflow dramatically. You can plug in an API key online or self-host (I added python + node.js boilerplates in the repo). Click the Octopus icon in the top right to change your model type, see your history, and change the number of prompt-response boxes you're working with. I'm open sourcing it here and want your feedback, both on the UX and the self-hosting experience!<p>This week I hope to add diff checking, batch API calls to speed things up, and options to add more LLMs.<p>[1] <a href="https://chainforge.ai/" rel="nofollow">https://chainforge.ai/</a>

<p>Cool idea - can you say more up front about how this works? I went through the (long) survey just to get a paywall with no information on what to expect.<p>Also, do you plan to offer a version of this for teenagers? I noticed the youngest age range is 20.</p>

<p>What data do you want to see? Most of it exists publicly but is very messy. You can get basic financial information here,[1] but data on student outcomes and school climate is very siloed - if there's a specific school/state you're interested in, I could help you find information.<p>Even if you're a researcher, good quality data rarely exists. In NYC, which collects more data than any other school district, you're mostly relying on a (publicly available) 100 question survey sent to every student. The survey author must have never talked to a child because the questions are worded like a clinical psychology paper. At low income schools the survey has a 20-30% response rate.[2]<p>[1] <a href="https://nces.ed.gov/ccd/schoolsearch/index.asp?ID=251275002087" rel="nofollow noreferrer">https://nces.ed.gov/ccd/schoolsearch/index.asp?ID=2512750020...</a>
