Pros

Within 1–4 points of Sol on core benchmarks (SWE-bench Pro 63.4%, Terminal-Bench 2.1 87.4%, GPQA Diamond 92.9%) at $2/$12

Strong long-context recall: 72.5% on 512K–1M tasks vs Luna's 41.3% collapse

July 30, 2026 price cut made it ~2x cheaper than GPT-5.5 for comparable capability

Cons

Big gap to Sol on computer use (OSWorld 50.2% vs 62.6%) — not a drop-in Sol replacement for agents

Well behind Claude Opus 5 on repository-level coding (SWE-bench Pro ~63% vs 79.2%)
