24 alternatives to We made GPT-4.1-mini beat 4.1 at Tic-Tac-Toe using dynamic context
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 HN! I've found this visualization tool immensely helpful over the years for getting an intuition for how an LLM "sees" some piece of text, and with a bit of elbow grease decided to move all compute to client side so I could make it publicly available. I've found it particularly useful for - Understanding exactly how repetition and patterns affect a small LM's ability to predict correctly - Understanding different tokenization patterns and how it affects model output - Getting a general sense of how "hard" different prediction tasks are for GPT-style models Known problems (that I probably…

Hi HN, I built TetrisBench, a benchmark that tests LLMs on real-time code generation and reasoning through Tetris. Live: https://tetrisbench.com/ *How it works:* Each model starts with an initial optimization function for evaluating Tetris moves. As the game progresses, the model sees the current board state and updates its algorithm—adapting its strategy based on how the game is evolving. The model continuously refines its optimizer: - Board getting too high? Prioritize clearing lines. - Hole forming? Adjust penalties. - Safe stack? Build for a Tetris. The model generates…

Most inference UIs that I've come across pretty much just give us a chat-like interface to toy around with models in a single visual conversation thread. Given the fact that we are limited to seeing only one output at a time, it's kind of hard to compare outputs from different models, adjustments made to the prompting, and sampler settings. But even when keeping the generation parameters the same (e.g., to test for reliability in the output) and just going for multiple passes, there is no easy way to have a side-by-side comparison to keep track of the outputs from the multiple "rounds". I…

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!

I’m excited to share a project I’ve been working on for over a year, which I believe will fundamentally change our approach to language models. We’ve designed a new architecture, which replaces the hidden state of an RNN with a machine learning model. This model compresses context through actual gradient descent on input tokens. We call our method “Test-Time-Training layers.” TTT layers directly replace attention, and unlock linear complexity architectures with expressive memory, allowing us to train LLMs with millions (someday billions) of tokens in context. Our instantiations, TTT-Linear…

Hey, it's been a long time in the making, but we're finally ready with our public BETA version of our Android application. We're anxiously (and nervously) awaiting your feedback, so please lay it on us. Our biggest fear is hearing nothing. The game is called Super Tic Tac Toe. It's a new take on the old, boring tic tac toe that more often than not ended in a cat's game. The game board is a large tic tac toe board with each square comprised of a smaller tic tac toe board. You and an opponent place your marks on the smaller boards, each move dictating where your opponent may move next (and…

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!

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…

I’m Andrew, co-founder of Recall. Over the past few days I’ve been building Predict, a playground where anyone can: - propose skills we should measure in language models—live examples include difficult math, memory-manipulation resistance, code generation, and empathy under bad news - write evals (graded prompts) for those skills - forecast which models will score highest once GPT-5 is released Why this exists Benchmarks leak into training data quickly; scores are unreliable and labs still declare progress.

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!
