按量付费

GPT-5.1 is the latest frontier-grade model in the GPT-5 series, offering stronger general-purpose reasoning, improved instruction adherence, and a more natural conversational style compared to GPT-5. It uses adaptive reasoning to allocate computation dynamically, responding quickly to simple queries while spending more depth on complex tasks. The model produces clearer, more grounded explanations with reduced jargon, making it easier to follow even on technical or multi-step problems. Built for broad task coverage, GPT-5.1 delivers consistent gains across math, coding, and structured analysis workloads, with more coherent long-form answers and improved tool-use reliability. It also features refined conversational alignment, enabling warmer, more intuitive responses without compromising precision. GPT-5.1 serves as the primary full-capability successor to GPT-5

选型摘要

快速判断是否适合你的工作负载

What is this model good for?

General reasoning, coding, and structured analysis

Use gpt-5.1 for broad tasks that need improved instruction adherence, clear explanations, and adaptive reasoning.

What should you check before using it?

Test conversational quality and task reliability

Evaluate multi-step reasoning, coding, tool use, and response style on representative prompts before changing default production routing.

How should you start?

Compare gpt-5.1 with your current GPT-5 baseline

Use model ID gpt-5.1 in the same client and evaluation harness as your current model, then promote it only after measured gains.
