OpenAI releases GPT-5.5 and GPT-5.5 Pro in the API

ThinkingNews Desk · how this was written

OpenAI has released GPT-5.5, its first fully retrained base model since GPT-4.5, which matches GPT-5.4’s per-token latency while delivering noticeably higher intelligence. The model is described as more efficient, better at coding and handling ambiguous tasks, with its strongest gains in agentic coding, computer use and early scientific research, and it narrowly outperformed Anthropic’s Claude Mythos Preview on the Terminal-Bench 2.0 benchmark.
