Notes from the sources
Grok 4.7
Standard, under 200K
Global-endpoint rate for prompts under 200K tokens. At or above 200K the pricing page lists $4 input, $1 cached input, and $12 output per 1M tokens for the whole request. The release notes say there is no text output limit, so max output is n/a rather than a guessed cap. They place the launch under September 2026 without a day on the page fetched. The US regional endpoint is billed at 1.1× these rates.
Mistral Medium 3.5
Standard
Standard USD rates from the API pricing table. The models overview lists status GA and a 256k context window, and describes the model as multimodal. A release day, max output, and a modality list were not on the pages checked.
