Analysis Summary
GPT-5.5 Pro from OpenAI extends the GPT-5.5 family with a 1.05M token context window, vision, tool use, and function calling, aimed at the most demanding workloads. However, no independent benchmark results are provided for this specific Pro configuration.
At $30 input and $180 output per million tokens, it is priced for high-value, low-volume tasks such as deep document review or premium client deliverables, not routine automation.
Until benchmark data confirms its edge over the standard GPT-5.5, treat this as a premium variant to trial selectively rather than a default choice.
