AIOpenRouter Batch API offers 71 models and three API formats
A promotional rundown says the API routes requests to the cheapest provider, supports users’ own API keys and avoids the need to manage separate file APIs or external storage buckets.
TLDR
A September 22 promotional rundown says OpenRouter’s Batch API supports 71 models, with a choice of /chat/completions, /responses or /messages for all of them. It promises routing to the cheapest provider and simpler request submission and response polling, without separate file APIs or external buckets to manage. It also lists bring-your-own-key support. A user sharing the rundown argues that many prompts would be better handled “slower and smarter and cheaper” in the background across multiple models.
