GPT-5.3-Codex 是否支持图像理解？
是的，其输入类型明确包含 'image'，表明具备图像理解能力。
该模型能否处理大文件输入？
支持 'file' 类型输入，结合 400,000 token 上下文，暗示可处理较大规模文件内容（具体格式与大小限制未披露）。
它是否专为代码生成优化？
名称中 'Codex' 沿袭 OpenAI Codex 系列命名传统，且描述强调‘编程及泛生产力领域’，表明代码相关能力为其核心定位之一。
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.
