OpenAI: GPT-5.2 Pro

GPT-5.2 Pro is OpenAI’s most advanced model, offering major improvements in agentic coding and long context performance over GPT-5 Pro. It is optimized for complex tasks that require step-by-step reasoning, instruction following, and accuracy in high-stakes use cases. It supports test-time routing features and advanced prompt understanding, including user-specified intent like "think hard about this." Improvements include reductions in hallucination, sycophancy, and better performance in coding, writing, and health-related tasks.

Tool useVisionReasoning

Why it stands out

400K-token context window handles longer documents and multi-turn conversations without truncation.

Combines tool use with reasoning — a strong baseline for agentic and multi-step workflows.

Multimodal input (vision) extends it beyond text-only workflows.

What to watch

Output pricing ($168/M) puts it at the high end — monitor generation length for cost control.

No benchmark score currently tracked — evaluate using task-specific testing alongside pricing and capability data.
