OpenAI: GPT-5.2 Pro
GPT-5.2 Pro is OpenAI's premium-tier variant of the GPT-5.2 family, with a 400K context window and full multimodal support, but it carries no independent benchmark data and commands a very high price. Without verified performance figures it cannot be scored above the conservative range, regardless of provider reputation.

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.
