advent0 pits AI models against each other on AdventJS 2025 coding challenges. Models are given the same challenge and must write JavaScript code to solve it. We measure who solves it first, with the fewest iterations, using the least tokens.
Unlike static benchmarks, battles happen in real-time with actual code execution. You can watch the models think, iterate, and debug their solutions live.
