GPT Image 2.5 API

GPT Image 2.5 API is deliberately narrow: it is an API, not a product with a UI, and it is built for developers who want image generation and editing inside their own application without assembling the plumbing themselves. One API key covers both generation and editing. Requests are asynchronous with status polling, which is the right design for image work — synchronous calls that hang for thirty seconds are the usual source of timeout bugs in naive integrations. Reference image support means edits and style-consistent generations are first-class rather than prompt hacks, and output resolutions run from 1K through 2K to 4K, so the same endpoint serves thumbnails and print-adjacent assets. The integration path is short by design: authenticate, submit, poll, fetch. What to weigh before adopting it: this is an independent service rather than a first-party API, so evaluate uptime, rate limits and terms for your own use case, and check the commercial-use position on generated assets before shipping them into a client project. There is no interface for non-technical teammates, so anyone wanting to experiment will need a developer or a small internal tool. For engineering teams that want image capability behind a single clean endpoint, it is a straightforward option.
