Benchmarks
Provider-reported (Mistral, May 2024): competitive with larger code models on HumanEval, RepoBench, and fill-in-the-middle benchmarks — provider-reported, now dated (2024); treat comparisons against 2025-2026 code models as stale.
Provider-reported unless a source says otherwise. Benchmarks are marketing-adjacent by nature — treat them as directional.
