GPT-5.5 Pro · impossibl

GPT-5.5 Pro is the high-compute version of OpenAI's GPT-5.5, aimed at deep reasoning and accuracy on complex, high-stakes workloads. It thinks harder to produce smarter, more precise answers than base GPT-5.5, runs only through the Responses and Batch endpoints, and may take minutes to respond, so background mode is recommended.
