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…

I build runcell, an AI Agent in Jupyter Lab. It can understand context (data, charts, code, etc) in your jupyterlab and write code for you. Runcell has built-in tools that can edit or execute cells, read/write files, search web, etc. Comparing with AI IDE like cursor, runcell focus on building context for code agent in jupyter environment, which means the agent can understand different types of information in jupyter notebook, access kernel state, edit/execute specific cells instead of handling jupyter as static ipynb file. Comparing with jupyter ai, runcell is more like an agent…

Built Playmaker to help busy founders and GTM folks execute faster. In its current form, think of it as an early GTM enabler. Under the hood, I repurposed David Zhang’s excellent deep-research project to auto-discover info about a business using just an email (extracts and analyzes the domain). What Playmaker does today: Generates unique campaign ideas (“plays”) tailored to your business Suggests the exact tool stack to execute each play Defines success metrics so you can work backwards with clarity What’s coming soon: Powerplays – curated, proven plays from top marketers and GTM frameworks…

Hello! I created SpicyChess(https://spicychess.com) because I wanted a tactics training app that would have the following features: - Spaced Repetition. - Countdown time to simulate blitz Chess where you have to find the best move quickly. - The ability to save puzzles for later review. I'd love to hear any feedback that you may have !

Hi HN, I've been working with LLMs in production for a while both as a solo dev building apps for clients and working at an AI startup. The one thing that always was a pain was to pay OpenAI/Gemini/Anthropic a few dollars a month just for me to say "test" or have a CI runner validate some UI code. So I built this server called ChunkBack, that mocks the popular llm provider's functionality but allows you to type in a deterministic language: `SAY "cheese"` or `TOOLCALL "tool_name" {} "tool response"` I've had to work in some test environments and give good results for experimenting…

We built an open-source library of 125 GTM (go-to-market) skills that plug into AI coding agents like Claude Code, Codex, and Cursor. With these skills an AI agent can automatically: - Find ICP leads from conference speakers, LinkedIn activity, or job boards - Generate personalized cold email sequences - Monitor competitor blogs, pricing pages, and hiring signals - Generate programmatic SEO pages from keyword lists - Track where your brand appears in ChatGPT, Perplexity, and Claude answers --- How skills work Each skill is a structured markdown file containing instructions, scripts, and tool…

Hello, This is something I've wanted to build for awhile (first bought the domain in 2020 (then lost it for a year+)). It's a tactics solver on each new tab page. There are 5 modes of play: Easy (<1200 elo) Medium (1200-1800) Hard (1800-2400) Expert (2400+) Speedrun (solve as many puzzles as possible in 60 seconds). I'm having a ton of fun with it, and definitely noticing improvements with actual games (definitely solved the most puzzles in my life while developing this extension). If you check it out, please let me know what you think. Any feedback is good!

Hey HN! I built self-driving sim and eval at Waymo. Now I’m building Scorecard to bring that approach to agent eval: reproducible, automated scoring for AI. Scorecard lets you: - Run LLM-as-judge evals on agent workflows: test tool usage, multi-step reasoning, and task completion in CI/CD or in a playground. - Debug failures with OpenTelemetry traces: see which tool failed, why your agent looped, and where reasoning went wrong. - Collaborate on datasets, simulated agents, and evaluation metrics.

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.

Hi, I am Bigyan from The Drive AI. We recently launched Chat Channels and Direct Messaging within The Drive AI. The Problem We're Solving: Current systems like Google Drive and OneDrive don’t utilize stored files to create new ones effectively. For instance, if you have a resume and a link to a job description, why can’t Google Docs write a resume for you? Team projects often involve file-specific tasks like reading or writing. However, existing team communication platforms, like Slack, result in inefficient communication due to their long threads of conversation. Have you ever posted in the…
