Cognition launches SWE-2 claiming frontier-level coding at 70% lower cost, but skips Terminal-Bench 4
steipete · x · 2026-09-11
- Cognition officially introduced SWE-2, its model closest yet to the frontier, claiming parity with recent frontier models on leading evals at up to 70% lower cost.
- The team says it scaled RL to multiple trillions of parameters, pushing the Pareto curve on both capabilities and cost.
- The thread's real point is a callout: Cognition conveniently posted its Terminal-Bench 2.1 score while omitting Terminal-Bench 4, prompting criticism that the announcement cherry-picks favorable benchmarks.
