Standard Series
gpt-5.6-sol
Flagship of the GPT-5.6 family and OpenAI's strongest reasoning and agentic model to date. Scores 42.2 on Agents' Last Exam — a benchmark of long-horizon workflows across 55 domains — leading peer models by a wide margin at lower cost. Excels at complex coding, long-range planning, and deep research, with up to 128K output tokens for demanding engineering and automation tasks.

gpt-5.5
An enhanced step up from GPT-5.4 at 2× the per-token cost, retaining the same 1M-token context window. Improves 9 of 10 shared benchmarks — ARC-AGI-2 (+11.7pp), MCP Atlas (+8.1pp), and Terminal-Bench 2.0 (+7.6pp) see the largest gains. Completes identical Codex tasks with fewer tokens and fewer retries, ideal for high-precision complex engineering.
