What shipped
xAI released Grok 4.7 on 21 September as `grok-4.7` on its public API, positioning the model for coding, agentic tasks and knowledge work. The release notes specify a 500,000-token context window, text and image input with text output, and four reasoning-effort settings: low, medium, high and xhigh. High is the default reasoning level.
The same model is also available through Grok Build, Cursor and model gateways. xAI says a faster serving variant runs at roughly twice the output speed and twice the token price, but that Fast variant is limited to Cursor and Grok Build rather than the public xAI API. The standard API release therefore has a broader integration path than the accelerated serving option.
Pricing doubles once prompts cross 200,000 tokens
For prompts at or below 200,000 tokens, xAI lists Grok 4.7 at $2 per million input tokens, $0.50 per million cached input tokens and $6 per million output tokens. Above that prompt threshold, the listed rates double to $4, $1 and $12 respectively. That long-context tier matters because the model can accept up to 500,000 tokens even though the cheapest rate applies only to the first pricing band.
xAI also says Grok 4.7 keeps the same base price as Grok 4.6. Its launch post publishes benchmark gains over 4.6 across several coding and professional-work tests, but those measurements are vendor-run. They establish xAI’s launch claims, not an independent performance ranking against other frontier models.
GitHub is adding the model across Copilot surfaces
GitHub separately announced that Grok 4.7 is rolling into Copilot for Pro, Pro+, Max, Business and Enterprise subscriptions. GitHub lists Visual Studio Code, Visual Studio, Copilot CLI, Copilot cloud agent, the GitHub Copilot app, JetBrains IDEs, Xcode and Eclipse among the model-picker surfaces receiving it.
The rollout is gradual, so GitHub explicitly warns that eligible users may not see the model immediately. Business and Enterprise administrators can control access through Copilot model policy; under GitHub’s default model-enablement policy, newly released models are enabled unless an administrator has disabled the global default or the model specifically.
Billing and evidence boundary
GitHub says Copilot use of Grok 4.7 is billed at provider list pricing under its usage-based billing system. The confirmed changes are the xAI API release and GitHub’s Copilot rollout, together with their published availability and pricing rules. Real-world coding quality, latency and cost will depend on workload, reasoning level, prompt length and the Copilot surface, so the model’s launch benchmarks should remain separate from deployment evidence.
