Poe API

GPT-5.5

GPT-5.5 is OpenAI's smartest and most intuitive model, built for agentic coding, computer use, knowledge work, and early scientific research. It handles complex multi-step tasks with less guidance, figures out what needs to happen next on unclear problems, and matches GPT-5.4 per-token latency while delivering a much higher level of intelligence. Achieves state-of-the-art accuracy on Terminal-Bench 2.0 and SWE-Bench Pro, solving more tasks end-to-end in a single pass than previous models. Supports 400k tokens of input context and native vision.
