Model overview
GPT-5.5 is OpenAI’s frontier model designed for complex professional workloads, building on GPT-5.4 with stronger reasoning, higher reliability, and improved token efficiency on hard tasks. It features a 1M+ token...
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
- Stronger reasoning capabilities compared to GPT-5.4
- Higher reliability and improved token efficiency on hard tasks
- Supports multimodal inputs (file, image, text) with text-only outputs
Limitations & considerations
Sources are insufficient to establish specific limitations. Verify task performance, latency, data policies, licensing and version lifecycle.

Is GPT-5.5 (batch) a publicly confirmed OpenAI model?
No — the model name 'GPT-5.5' is not verified by OpenAI; it appears only in third-party listings (e.g., OpenRouter) and is not referenced in official OpenAI communications.
What is the maximum context length of GPT-5.5 (batch)?
The context length is reported as 1,050,000 tokens.
Does GPT-5.5 (batch) support image understanding?
It accepts image inputs per the 'inputs' field, but official documentation or validation of image understanding capability is not provided in the source.
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.
