Model overview
gpt-oss-20b是OpenAI在Apache 2.0许可下发布的开放权重的21B参数模型。它使用混合专家（MoE）架构，每次转发传递3.6B活动参数，针对低延迟推理和可部署性在消费者或单gpu硬件上进行了优化。该模型以OpenAI的Harmony响应格式进行训练，并支持推理级别配置、微调和代理功能，包括函数调用、工具使用和结构化输出。

该模型是否开源且允许商用？
是的，模型以Apache 2.0许可证发布，允许自由使用、修改和商用。
它能否在单块消费级GPU上运行？
是的，设计目标明确包含在消费者或单GPU硬件上的可部署性与低延迟推理。
是否支持函数调用和结构化输出？
是的，官方描述明确指出支持推理级配置、函数调用、工具使用和结构化输出。
Do open weights permit free commercial use?
Not necessarily. Check the version license, commercial conditions and usage policies. Self-hosting incurs compute and maintenance costs.
Are these real-time billing prices?
These are timestamped source snapshots, not live billing prices. Check the channel for current versions, regions, discounts and billing methods.
