The Real-World AI Coding Benchmark

Not synthetic tests. Not isolated evals. The first leaderboard built from actual developer sessions — measuring how well AI models collaborate with real engineers under real pressure.

Powered by AlgoArena OA sessions. Every assessment contributes anonymized data.

No spam. We'll only email you when rankings go live.

Sample data for illustration. Actual rankings will be computed from anonymized OA session metrics.

Not Another Synthetic Benchmark

Most AI benchmarks test models in isolation. We measure how models perform when paired with real humans on real tasks.

Synthetic Benchmarks

HumanEval · SWE-bench

  • Isolated, no human in the loop
  • One-shot generation
  • Static test suite

Chatbot Arena

LMSYS · ELO Rankings

  • Human preference data
  • Conversational, not code-specific
  • No time pressure / stakes

AlgoArena Benchmark

Real-World · Live Data

  • Real engineers, timed sessions
  • Multi-file, real-world tasks
  • Accept/edit/reject + test pass

What We Measure

Every OA session generates rich signal about AI–human collaboration quality.

First-Try Pass Rate

Percentage of AI suggestions that pass all test cases without human edits.

Suggestion Acceptance Rate

How often candidates accept AI output verbatim vs. editing or rejecting it.

Design Quality Score

Auto-graded architecture, readability, and maintainability of AI-assisted code.

Time-to-Solution

How quickly candidates reach a passing solution when using each model.
