OpenAI: o1 (batch) no longer appears in the OpenRouter catalogue. The record stays here because the measurements below were real when they were taken and this address has been published. A model leaving is the kind of change this product exists to notice, so it is kept rather than deleted.
This entry is a serving variant of OpenAI: o1. A variant shares its base model's tokenizer by construction, so the measurement lives on the base record and this page inherits it.
