Frontier position
- On frontier AA coding index (blended per-1M-token price, 3:1 input/output; not a measured per-task cost) - no tracked model currently beats it on both price and capability.
- Behind frontier AA intelligence index (blended per-1M-token price, 3:1 input/output; not a measured per-task cost) - Claude Opus 5.5, Muse Wonder, Gemini 4 Argon, Claude Sonnet 5.5, GPT-6.1 Sol are priced the same or lower and at least as capable.
- Behind frontier DeepSWE pass@1 (agentic coding) (measured USD per task) - Gemini 3.8 Flash is priced the same or lower and at least as capable.
