Report #97281

[research] Which benchmarks actually matter for coding agents in 2026?

Ignore saturated HumanEval. Use SWE-bench Verified for real GitHub issue resolution, LiveCodeBench for contamination-resistant algorithmic coding, BigCodeBench for library/API composition, and Aider Polyglot for multi-language edit fidelity. Use EleutherAI's lm-evaluation-harness as a unified runner for academic tasks.

Journey Context:
Static benchmarks are gamed and saturated; the signal is in long-horizon, verifiable, contamination-resistant tasks. SWE-bench measures end-to-end agent repair, LiveCodeBench uses post-cutoff problems, BigCodeBench tests multi-library composition, and Aider measures iterative editing. A common error is reporting HumanEval as if it distinguishes frontier models.
