What is GPT Image 2.5 Flare?
GPT Image 2.5 Flare is an image model that turns text and reference images into new images, built by OpenAI and served on LLM API under the id gpt-image-2.5-flare.

The prices, context window and provider routing below come straight from the live catalogue and are refreshed every week.
Can you self-host GPT Image 2.5 Flare?

ERRORS
Errors & fallback routing
| Code | What it means | What to do |
|---|---|---|
401 | Missing or invalid API key. | Send Authorization: Bearer YOUR_LLMAPI_KEY and check the key is active. |
429 | Rate limited, or the upstream provider is throttling the request. | Back off and retry with jitter; the gateway also retries the request on another provider where one is available. |
5xx | Upstream provider error or timeout. | Retry; fallback routing sends the retry to the next healthy provider for this model. |
When a provider fails or throttles, the request is routed to the next provider serving this model — the ones listed in the providers table above.
