How we rank
The list includes text models from established vendors that OpenRouter added in the last 12 months, with at least a 32,000-token window. Batch, preview, experimental and image or audio generation variants are left out; batch prices appear in their own column on vendor pages. Prices are the current per-token list rates; for open-weight models served by several hosts, OpenRouter shows the price of the provider it currently routes to, which is why some of them move often.
