OpenRouter’s Auto is a general-purpose router that selects a model for each request and adjusts how much reasoning it uses. The company says it aims to choose cost-optimal models while balancing task difficulty, benchmark results and live prices.
OpenRouter lists a context window of 2 million tokens. The page does not identify which models Auto may choose or explain how its costs are calculated.
Why it matters
People using OpenRouter can hand off model selection to Auto, but the page does not say which model it will choose or what a request will cost.
