Start with the simple view: the cheapest reliable option, the official provider price, and the best places to try or deploy this model. The detailed table stays below if you want the full pricing breakdown.
Public pricing, no login required. Rates are in USD and billed by the provider, separately from AI Market Cap data plans. Confirm billing cycle, taxes, usage caps, and specific model availability before purchasing. A subscription does not automatically include API credits; context length, caching, and tools can change usage costs.
Official provider access is separated from brokers and routers, so the lowest price does not get confused with the first-party route.
