Code generation & program synthesis — Benchmark Sources & Consensus

Generating or reconstructing working programs from specs, binaries, or natural-language descriptions. Frontier-difficulty benchmarks where state-of-the-art is still well under 10%.

Platforms tracked: Claude Cowork · Kilocode · Openclaw · Chatgpt

Consensus across 2 sources

Across 2 sources, the two available data points measure different things and neither separates platforms cleanly. ProgramBench (May 2026) sets a difficulty ceiling: 0% of evaluated models fully solve program reconstruction from binaries, with the best reaching 3% "almost resolved." A framework-level benchmark (August 2026, 21 Rails tasks, 8 models) reports 92% top accuracy but finds models reach for existing framework APIs only 8-35% of the time, and score higher when they do — suggesting idiomatic-code use, not raw task success, is where current models differ.

We aggregate published benchmarks; we never run our own tests and never pick winners. Each row links back to the original publication.

How we work

OpenClawDatabase aggregates and links to published benchmarks. We don't run our own tests, and we don't pick winners. Our weekly benchmark-aggregator routine scans 7+ live leaderboards (OpenRouter, Aider, SWE-bench, GAIA, LMSYS, BigCodeBench, MMLU-Pro) plus relevant Reddit and Hacker News threads, then writes structured entries into /assets/benchmarks.json. Every row here links back to the original publication.
