OpenRouter drops unified API for 30+ image models
OpenRouter has launched a dedicated Image API that standardizes access to over 30 image generation models from eight providers. The new endpoint normalizes fragmented request schemas and introduces dynamic capability discovery so agents can adapt to parameter constraints automatically.
Image generation APIs have historically been a fragmented mess of differing aspect ratios, token limits, and payload structures. OpenRouter is doing for image models what they already did for LLMs—abstracting away provider headaches to let developers focus on building.
- –Capability descriptors let coding agents dynamically read supported resolutions and constraints without hitting trial-and-error 400 errors
- –The unified request shape normalizes parameters across providers while still allowing specific features via a passthrough object
- –Transparent, granular pricing handles the mess of per-megapixel versus per-token billing directly in the usage response
- –Native SSE streaming support for OpenAI's GPT models allows developers to render partial previews instead of spinners
