Pros

80.6% SWE-bench Verified (self-reported) — reported as tied with Gemini 3.1 Pro

93.5% LiveCodeBench and Codeforces 3206 — elite competitive-coding results

1M context with 384K max output at $0.87/1M output — an order of magnitude cheaper than closed frontier models

Cons

Independent harnesses report much lower agentic scores than the self-reported numbers; trails GPT-5.6 and Opus-class on hard agentic evals

Peak-hour surge pricing doubles rates, a price increase is announced, and it's text-only (no vision)
