    Spelltest framework simulates conversations between AI ‘synthetic users' in an environment to test and refine LLM-based applications. It ensures your app converse with utmost accuracy and relevance. Post-chat, Spelltest assesses responses, providing qualitative and quantitative feedback on performance. Suitable for both chat and completion modes. When to use: - After modifying your prompt. - When your LLM provider updates. - As a CI step for you repo. All feedback and collaborations appreciated!

    Hey HN, We've been hard at work on a tool that we believe will change the game for developers, data scientists, and anyone working with models that rely on textual prompts. I'm excited to introduce our new tool: Automated Prompt Engineering (APE). Problem: As many of you know, how you phrase a prompt can significantly impact the results you get from models, especially with sophisticated language models. It often requires numerous iterations to hone in on the right prompt to obtain the desired response. Solution: APE is designed to tackle this exact problem. With APE, you can: - Iterative…

    Hi HN, I'm pleased to share Promptspot, an open-source (Apache License 2.0) project that helps automate testing of large language model (LLM) prompts against an array of input data. Modern LLMs offer an enormous amount of leverage if you "teach the bot to fish" — i.e. simply prompt it with both a "system prompt" (which typically doesn't change often) and a dynamic input, which is often application state, search results, recent activity, user profile data, etc. Existing playgrounds and prompt management systems often lack the rigor and flexibility required for this dynamic approach — and as…

    Test your prompt engineering skills by writing prompts and battling them against each other! Your prompt template can access the board state, the move history, and a list of legal moves, and the game engine selects the first legal move in the string response from the LLM you query. My best prompt so far ignores the board state and the move history and just tries to play mates, make captures, and promote pawns. Can you do better?

    Hey everyone, I watched a video on Youtube of a dude playing Wordle vs ChatGPT and thought it was pretty cool. So, I went ahead and made my own version of it. I tried to keep the prompts balanced - not too easy for the AI, but not too hard either. Give it a try and let me know what you think. Thanks!

    Promptle – The Daily AI Prompt Challenge What if Wordle met ChatGPT? Ever feel stuck trying to get the right output from ChatGPT or Midjourney? The idea sparked from a simple thought: “What if Wordle met ChatGPT?” I wanted to gamify the creative process of writing AI prompts—a skill becoming as vital as coding. As an avid prompt tinkerer and daily Wordle player, I felt there was a missing intersection between creative constraint, feedback, and skill-building. Thus, Promptle was born: a daily game where players write prompts instead of guesses, and creativity—not just logic—is the path to…

    Hey guys, I’ve been playing around with this prototype for a way to build games using GPT. Some details: - It’s an absolute hack right now; expect bugs and user unfriendliness. Also UI is not fixed for mobile yet (use desktop). - It’s top-down, 2d. You view the world from above, and you can move around by clicking and dragging the world. - It’s using gpt-4-turbo under the hood, and I’m outputting typescript code, which gpt will self-repair when there are type errors. - Here’s a simple example game: https://prompty-58a21.web.app/dune/play So far I’ve been quite impressed…

    Hi HN, We're a small team building AI tutors out of India, and as you might guess, this means we spend a ton of time writing, testing, and refining prompts for LLMs. When we started out, we were using the OpenAI playground but things became tedious when we wanted to compare responses from different models. We tried a bunch of other playgrounds but found them lacking in some features so we built our own.

    I had a lot of fun with this one. She's used it several times, and I watch, to see what subtle bugs or ux issues there may be. And when she gets on the bus I fix them quickly before work. It's been a fun game to create where it gives here immediate feedback and she's willing to study more. Her test is this Friday. fingers crossed that it helped her!

    Hey all, just wanted to share a little game experiment. It's a rooms & keys kind of adventure with a lot of random deaths. It plays a Veo3-generated video in response to clicks, with Gemini used for coding. Prompting the videos was fun, but trying to vibe code everything was not. In the future I'll go back to using LLMs more sparingly for isolated functions, or at least try not to have it create anything that requires seeing the output to debug.

    Hi HN, Today we're launching a tool to help you evaluate and test prompts for Generative AI. We have been building different GPT3 apps and noticed a gap in tooling to help developers assess the quality of different prompts. Our tool helps you template and test on different datasets and LLM models like GPT-3, GPT-3.5 and open source models like flan-t5-xxl. We are just getting started and would be delighted to receive your feedback.

    I loved the role-playing exercises I did during my MIT negotiation classes, but many of my classmates are too busy now to continue them after the classes have ended. Before ChatGPT/GPT-4, good negotiation AIs to practice with weren't really possible. So, I thought building short GPT-4 powered simulations to teach basic negotiation concepts would be a fun thing to do :). Let me know how you do!

    We wanted to test if a smaller model like GPT-4.1-mini could beat its bigger brother 4.1 at the game Tic-Tac-Toe using only context engineering. We put them in a 100-game tournament. For the smaller model, we gave it a few examples of winning moves from past games right before it made its own move. The results were clear. Without the examples, the smaller model struggled against GPT-4.1. With the examples, its effectiveness increased by nearly 200%, and it consistently won. It's a simple demonstration, but it shows that a smaller, faster model with good, timely examples can outperform a more…

    Hi I've created a text-based RPG game in which you can experience different adventures and play interesting characters while the AI acts as a real time DM/story teller. There are multiple ways to interact with AI: 1) Input free will move 2) Input default move (affects resources) 3) Post a question to DM Also one more cool feature is that you can create your own adventure via simple form. Add scenes, add characters and make it public so other players are able to test it. I also plan to have 'competetive' side where players will pay some small fee to creators in crypto depending on…

    Built this with my roommate over the weekend. At the end of the game, GPT will share its reasoning for each choice, which yields some funny results and explains why its so hard to win. Enjoy!
