Is GPT-5 Image Mini officially released by OpenAI?
No — the model is listed on OpenRouter under 'openai/gpt-5-image-mini', but there is no public confirmation from OpenAI that it is an official OpenAI release.
What is the maximum context length for GPT-5 Image Mini?
The context length is 400,000 tokens, as specified in the provided data.
Does GPT-5 Image Mini support structured output formats?
Yes — 'structured_outputs' is explicitly listed among its tags.
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.
