grok-4.7-build-fast

Description

Grok 4.7-build-fast, supplied through a single reseller route. Supports text and image input, streaming, and function tools in Chat Completions and Responses. Reasoning is billed as output; output limits apply to visible text. The supplier adds a billable input prefix. On Responses, send the full conversation and preserve encrypted reasoning items; previous_response_id, conversation references and server-side tools are not supported. Published context limit: 500K tokens; the full limit is not independently qualified. When total input is > 200,000 tokens, input/cache-read/output rates for the entire request, not only the excess, are 1.5 times the short-context rates: USD 6 / 1.5 / 18 per million tokens.
