Model overview
GPT-5.5 Pro is OpenAI’s high-capability model optimized for deep reasoning and accuracy on complex, high-stakes workloads. It features a 1M+ token context window (922K input, 128K output) with support for...
The summary below is compiled from sources by an AI model, not our own testing. Verify selection decisions against original sources and your workload.
Key features
- 支持超长上下文窗口（1,050,000 tokens），其中输入最多922K tokens，输出最多128K tokens
- 专为深度推理与高风险复杂任务优化，强调准确性
- 支持多模态输入（文件、图像、文本），输出仅限文本
Limitations & considerations
- 输出模态受限，仅支持文本，不支持图像、音频或代码执行等原生输出形式
- 仅提供 batch 模式调用（非实时流式响应），可能不适用于低延迟交互场景
- 未提及对结构化输出（如 JSON Schema）的强制保证或工具调用的运行时验证机制

GPT-5.5 Pro (batch) 是否支持图像理解？
是的，根据输入资料，其 inputs 包含 'image'，表明支持图像作为输入模态。
该模型能否处理超过100万token的输入文档？
否，上下文总容量为1,050,000 tokens，其中最大输入长度明确限定为922K tokens，不可超出。
它是否能直接调用外部工具或API？
资料中 tags 包含 'tools'，表明具备工具调用能力，但未说明是否在 batch 模式下实时触发或需额外编排。
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.
