Model data. Verified-price snapshots from . Details
35 of 39 tracked models have verified token rates in the saved catalogue. Rates come from the OpenRouter public API. Models missing from that catalogue have unknown pricing and are excluded from cost estimates and chat selection.
Rates are USD per million text tokens. Caching, reasoning tokens, images, tool charges, provider routing and long-context tiers can change the bill. Check the provider before budgeting.
Context limits have their own dated review. The Context Budget Planner shows the catalogue and top-provider quotes separately, using the smaller known limit. Output caps are a separate constraint. Weight links identify repository revisions whose file lists were checked. Licence labels come from the model cards and are not an open-source certification. Check the actual terms and access conditions. Published weights do not make a hosted API or self-hosting free.
Get a key from openrouter.ai/keys. Sending a message sends your key to OpenRouter for authentication and your conversation to OpenRouter and the selected model provider. Provider charges apply.

Costs shown are estimates for completed text replies. They use provider token counts when returned, otherwise a rough text estimate. Cached tokens, reasoning, routing and interrupted requests can change the bill. Your provider's usage record is the source of truth.
