Data verifiedHow BenchLM shows Vals Terminal-Bench 2.1 mirror
BenchLM mirrors the public Vals AI Vals Terminal-Bench 2.1 mirror leaderboard captured from https://www.vals.ai/benchmarks/terminal-bench-2-1 and updated by Vals on July 22, 2026. The snapshot preserves overall scores, uncertainty, latency, cost-per-test metadata, and task-level scores where Vals publishes them.
Vals Terminal-Bench 2.1 mirror is display only on BenchLM. Vals proprietary or Vals-hosted aggregate views are useful context, but BenchLM does not use them as weighted ranking inputs or as a replacement for benchmark-native source records.
