Pareto Code Router

Released Apr 21, 2026200,000 context

The Pareto Router is a way to have OpenRouter always pick a strong coding model for your needs without committing to a specific one. You express a single min_coding_score preference between 0 and 1, and the router routes your request to a coding model that meets that bar.

The Pareto Router is tuned for coding use cases. Under the hood it keeps a curated shortlist of strong coding models currently available on OpenRouter. The exact shortlist and selection logic evolve over time as new models land and benchmarks shift.
