概述
GPT-5 是 OpenAI 迄今为止最智能的模型,在推理、可靠性和专业用例方面带来了重大提升。
- 动态推理(“对此进行深入思考”)能够在复杂任务上提供专家级别的回答。
- 在前端复杂生成方面表现大幅提升。
- 在健康相关问题上是目前最好的模型。
- 模型幻觉显著减少(与 o3 相比,开启思考模式后减少约 80%)。
它支持 40 万 token 的上下文窗口,以及最多 12.8 万 token 的输出。
该模型的早期迭代版本曾以 Horizon Alpha 和 Horizon Beta 的名称提供。

Overview
GPT-5 is OpenAI’s most intelligent model yet, and it brings major gains across reasoning, reliability, and specialized use cases.
- Dynamic reasoning (“think hard about this”) enables expert-level responses on complex tasks
- Much better at complex front-end generation
- Best model yet for health-related questions
- Significant reductions in hallucinations (~80% less with thinking mode vs. o3)
It supports a 400,000 token context window and up to 128,000 output tokens
Earlier iterations of this model were available as Horizon Alpha and Horizon Beta
