Anthropic reports that infrastructure configuration alone can shift agentic coding benchmark scores by several percentage points, with internal tests showing a 6-point gap on Terminal-Bench 2.0 between highest- and lowest-resourced setups, exceeding gaps between top leaderboard models.

Concrete numbers and a p-value back a claim that the runtime environment is part of the problem, not a passive container. Useful counterweight to treating leaderboard deltas as decisive when choosing models.
