Pricing	usage	usage
Strengths	+ Deepest reasoning of the Claude family + Best for ambiguous, planning-heavy tasks	+ Half the per-token price of GPT-5.5 while staying in the frontier coding/professional tier + 1M-token context window with up to 128K output tokens + mini variant targeted at subagent and computer-use workloads for high-volume agent fleets
Tradeoffs	− Highest cost tier — not viable as default model − Higher latency than Sonnet / Haiku	− OpenAI directs complex reasoning and coding to GPT-5.5 instead − Older knowledge cutoff (Aug 31, 2025) than GPT-5.5
