OpenRouter's price is its image output token rate (openrouter.ai/api/v1/models, checked October 2, 2026) times Google's documented tokens per image. Input text and references are billed separately.
Per the openrouter.ai/api/v1/models list on October 6, 2026: it has no video generation models, and no FLUX.2 Pro, Grok Imagine or ElevenLabs.
Batches of thousands of images: a job queue, asynchronous 202 responses instead of timeouts, retrying only the failed jobs, and a budget before you start. See the price guide for every Nano Banana setting.
The :free and :online variants are not supported. Remove OpenRouter routing parameters (provider, models, route, transforms) from the request: the gateway picks the route itself.
