- Coding: Function calling, structured outputs, code execution, prompt caching, multi-turn tool use. Targets long-running coding sessions inside Cursor and GitHub Copilot.
- Agentic workflows: Server-side tool routing via third-party harnesses; web search and X search tools via the Grok API.
- Multimodal input: Text and image input with text-only output. The model understands screenshots and diagrams but does not generate images.
There is no Batch API for Grok 4.7 - xAI has not shipped batch support for any Grok model as of September 21 (aisignalhq.com, September 22, 2026). The model is also not licensed for redistribution; the proprietary license applies to all Grok 4.x releases.
How to access Grok 4.7 today
Five access paths on launch day:
- Grok Build: Free trial at x.ai/build; ships the model to coding workflows.
- xAI Console: Pay-as-you-go at $2 / $6 / $0.50 per million tokens; API model ID `grok-4.7`.
- Cursor: Default for CursorBench-grade workflows inside the editor; Pro and Business tiers supported.
- GitHub Copilot: Rolling out to Pro, Pro+, Max, Business, and Enterprise SKUs through the model picker; default-on unless admin disables (GitHub Changelog, September 21, 2026).
- Third-party routers: OpenRouter and competitors list Grok 4.7 at $1.60 input and $4.80 output per million tokens - cheaper than xAI direct, with the same model behaviour (llmreference.com, September 21, 2026).
OpenRouter's lower price is structural; aggregators buy in bulk and pass savings through. For sensitive code that needs EU data residency, xAI direct is the safer pick.
How Grok 4.7 compares to the frontier
Grok 4.7 lands in a crowded early-September window alongside GPT-6 Sol and Luna (September 22) and Claude Opus 5.5 (September 22). On CursorBench 4.0, xAI positions Grok 4.7 at the frontier of price-performance - the position Anthropic claims for Claude Opus 5.5 and OpenAI claims for GPT-6 Sol.
The detailed comparison math depends on your workload.
Grok 4.7's $2 / $6 per million undercuts GPT-6 Sol's $5 / $30 by 2.5x on input and 5x on output; it matches GPT-6 Luna's $1 / $6 input tier at slightly higher output pricing.
Versus Claude Opus 5.5's $4 / $20, Grok 4.7 is half the input price and a third of the output price (xAI pricing, September 21, 2026; OpenAI API pricing, September 22, 2026).
On agentic coding - the workload xAI specifically targeted for Grok 4.7 - CursorBench 4.0 favours Grok for long-running tasks; FrontierCode 1.1 favours GPT-6 Sol; SWE-bench Multilingual favours Claude Opus 5.5. Pick the model that matches the test your workload is graded against.
What was not announced
Three items stayed off the launch post. First, no image or video generation - Grok 4.7 is text-only output, multimodal input; image gen remains a separate product path.
Second, no Batch API. Grok 4.7 does not support xAI's batch endpoint; customers running overnight jobs pay full price or route through third-party batch offerings.
Third, no formal context-window expansion. Grok 4.6 also shipped at 500K; Grok 4.7 keeps the same ceiling. Customers whose workloads need 1M+ tokens continue to use OpenAI's GPT-6 Astra or Anthropic's Claude Opus 5.5 (aisignalhq.com, September 22, 2026).
Frequently Asked Questions
Is Grok 4.7 cheaper than Grok 4.6?
No - Grok 4.7 ships at the same headline API price as Grok 4.6 ($2 input / $6 output / $0.50 cached per million tokens, under 200K prompt). It is a quality upgrade rather than a price change (x.ai news, September 21, 2026).
Does Grok 4.7 support image generation?
No - Grok 4.7 is text-only output. It accepts text and image input, so you can feed it screenshots and diagrams for analysis, but the response is text. For image generation, xAI continues to offer Aurorasa and other imaging models on the same API (xai.com, September 2026).
Can I use Grok 4.7 on GitHub Copilot free tier?
No - GitHub Copilot requires Pro, Pro+, Max, Business, or Enterprise for Grok 4.7 access. Free-tier Copilot subscribers do not get Grok 4.7 in the model picker (GitHub Changelog, September 21, 2026).
What is Grok 4.7's knowledge cutoff?
May 2026. Grok 4.7 was trained on data up to May 2026 and may not know about events after that month. The X search tool inside Grok Build adds live signal from the social network for breaking events (llm-stats.com, September 21, 2026).
Should I switch from Grok 4.6 to Grok 4.7?
For coding-agent workflows inside Cursor or the Copilot cloud agent, yes - the quality gain on long-running tasks is the headline xAI pitch. For Free-tier or chat workloads, the difference is smaller and Grok 4.6 remains a serviceable fallback at the same price tier.
Does Grok 4.7 have a faster variant?
Yes - xAI publishes a fast variant of Grok 4.7 served at 'twice the output speed at twice the price' on the API. The fast variant is targeted at low-latency code completion rather than long-running agentic coding (x.ai news, September 21, 2026).
