Category	model	model
Vendor type	commercial	commercial
Pricing	usage	usage
Strengths	+ Excellent tool-use and structured-output reliability + Long context supports large codebases / document sets + Best-in-class for agentic coding workflows	+ 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	− More expensive than Haiku for high-volume classification − API-only (no on-prem / open weights)	− OpenAI directs complex reasoning and coding to GPT-5.5 instead − Older knowledge cutoff (Aug 31, 2025) than GPT-5.5
