I Built a Capture the Flag Arena for Agents

AI-powered debate arena where you compete and receive skill ratings for your argumentation.
u/Bakari2Sense · Reddit
Built a persistent skill rating for debate, like a chess rating but for argumentation I built a persistent skill profile for debate called the Debate Fingerprint. Would love feedback. [Founder disclosure: I'm Bakari, building 2Sense at app.2sense.ai] The idea: every debate you complete scores you across 6 dimensions (Logic, Structure, Responsiveness, Persuasion, Emotional Control, Clarity) on a 0-1000 scale. The scores persist across all your debates and build a visual profile over time

Check out what I just built with Lovable!

Train software skills by practicing algorithms with AI agents that build and test code.

Free consumer product, seat-based education product, enterprise assessment product. Same codebase. Is this survivable? Three motions off one core. Students practice free and generate cost, not revenue. Educators pay per seat. Hiring teams are the expensive product and the reason any of it matters. The free tier feeds both paid ones and that's the only thing justifying it. Education is slow, cheap, sticky. Hiring is faster, pricier, and churns the second the role gets filled. Billing got

Watch two randomly paired LLMs sword-fight in a physics arena and blind-vote which performed smarter.

I built a site where two LLMs sword-fight in real physics and you blind-vote who's smarter Two months ago I thought: what if the AI benchmark was just… watching them fight. So: https://stickblade-arena.vercel.app Two random LLMs get stickman bodies in a pymunk physics arena They each turn output JSON moves (swing, block, dash, shoot bow, throw flail…) Ragdolls, momentum, weapon collisions, the whole bit You watch the replay without knowing which model is which and vote who f

Chat with AI models, compare them, and vote to shape a community leaderboard.
u/Rabus · Reddit
I got TestingModels too overcomplicated over the month it is running: looking for some feedback how to make it more useful and simpler I run a benchmark like arena.ai , but with pre-generated prompts. So far, nearly 6k people came in and like 30k comparisons has been made - which means the thing is genuinely useful for people to compare the models. The problem is the more features i started adding the more overblown and complicated UI became - like old internet explorer tab bars Old: ht

A platinum record that plays in every arena in America. An archive of where it has happened, and the three people from Stone Mountain who made it.

Play 16 arcade games in Mech Arena

Deployed the 16 games built with Codex and GameBlocks. A few examples: Most of my time is actually spent shaping the player experience. Many ideas emerge through playing and exploration rather than from the initial design — the loop seems to be build → play → discover → improve. Is it possible to build an agent harness that supports this discovery loop — not just one that optimizes against a predefined spec? Full game list:
