Grok 4.7 — xAI
xAI's real-time, no-filter flagship, retooled for coding. 500K token context and $2/$6 per million tokens — the lowest output price of any flagship at its tier, though no longer the cheapest model on this site. Grok 4.7 keeps every spec and price from 4.6; the upgrade is all capability, and a modest one.

Overview
Grok is xAI's flagship AI assistant, built with a uniquely aggressive, unfiltered personality. Unlike other AI models that lead with corporate disclaimers, Grok gives you direct answers — sometimes with a sense of humor. Access it at grok.com or through the X (formerly Twitter) platform.
Grok 4.7 landed September 21, 2026, six weeks after 4.6. The spec sheet is unchanged — 500K context, $2/$6, text and image in, text out — and so is the price. New this time is a Fast variant: double the output speed at double the price ($4/$12), but only inside Cursor and Grok Build. Its lineage still runs through Cursor, which SpaceX agreed to buy for $60 billion in June after merging with xAI in February, and whose developer sessions trained the 4.5 line.
Read the spec sheet honestly: the 4.x line traded breadth for coding. Context halved from Grok 4.3's 1M to 500K back at 4.5, and native video input is still gone. What you get back is a model that inspects repos, edits files, runs commands, and retries after errors. On Artificial Analysis's rescaled Intelligence Index (v4.3.2), 4.7 scores 46 against 4.6's 44 — a real step, but a small one, and well behind GPT-6 Astra at 53.
The pitch is still price, but it's a narrower pitch than it was. At $2 / $6 per million tokens with cached input at $0.50, Grok 4.7 matches GPT-6.1 Sol on input and undercuts its $10 output. It is not the cheapest model around any more: GPT-6 Luna ($0.10/$0.50) and Gemini 3.8 Flash ($0.75/$3.75) are far cheaper, and Sol scores 52 to Grok's 46 on the same index. And don't read xAI's 46.3% on CursorBench 4.0 as a coding win — Anthropic reports 57.8% for Claude Opus 5.5 on the same benchmark. One early measurement also has 4.7 using more than twice 4.6's output tokens per task, which would eat into that per-token saving.

Key Capabilities
500K Token Context
500,000-token window — half of Grok 4.3's, unchanged from 4.5, still enough for most real codebases
Agentic Coding
Inspects repositories, edits files, runs commands, and retries after errors. The 4.x line was trained on real Cursor developer sessions
Three Reasoning Levels
Configurable effort: low / medium / high, defaulting to high. Dial down for latency-sensitive work
Real-Time X/Twitter Data
Native access to live public posts and trends
DeepSearch
Extended research mode scanning multiple web and X sources with citations
Benchmarks, Honestly
46.3% on CursorBench 4.0 (xAI's own number). 46 on the Artificial Analysis Intelligence Index v4.3.2, up from 4.6's 44 but well behind GPT-6 Astra's 53. Function calling, web search, X search, and code execution built in
Custom Voices & Voice Library
Clone a voice from a short recording and manage it via the xAI console, now paired with the grok-voice-think-fast-2.0 speech-to-speech stack
Aggressive Pricing
$2 / $6 per million tokens, $0.50 cached input. Same input price as GPT-6.1 Sol, 40% less on output — cheap for its tier, not the cheapest model overall
03
Pricing
| Tier | Price | Details |
|---|---|---|
| Free | $0 | ~10 prompts / 2 hours on older models. No DeepSearch, no image generation. |
| SuperGrok Lite | $10/mo | Entry paid tier. Grok Imagine plus one AI agent. |
| SuperGrok | $30/mo ($300/yr) | 100 default, 30 Think, 30 DeepSearch requests / 2 hrs. xAI hasn't said which Grok version the consumer apps run. |
| X Premium+ | $40/mo | High usage caps + X social features. |
| SuperGrok Plus | $100/mo | Reported in August, not confirmed by xAI. Sits between SuperGrok and Heavy. |
| SuperGrok Heavy | $300/mo | Largest quotas and Grok 4 Heavy. |
| API (Grok 4.7) | $2 / $6 per 1M tokens | Input / output under 200K tokens. Cached input $0.50/M. Also on Cursor, Grok Build, third-party harnesses and routers. Fast variant: $4 / $12, Cursor and Grok Build only. |
| API (>200K tokens) | $4 / $12 per 1M tokens | Requests past 200K total tokens double to extended-context rates. |

Reasoning effort: high. Work through this repo end to end: find every place [pattern] is used, change it to [new pattern], run the test suite, and fix what breaks. Report only what you changed and what still fails.06
Limitations
Verbose — one early measurement has 4.7 spending roughly twice 4.6's output tokens per task, so per-task cost can rise even at the same per-token price. Need speed? The Fast variant doubles it, and the price, in Cursor and Grok Build only
Context is 500K, down from 4.3's 1M, and native video input was removed at 4.5 and still isn't back in 4.7 — if you built on either, grok-4.3 (1M context, $1.25/$2.50) is still listed and still the model you want
The model itself can't generate images — that's Grok Imagine, and it still lags Nano Banana for typography-heavy work. If you call grok-imagine-image-quality, move to grok-imagine-image-2.0 before it retires on Nov 2
Requests past 200K total tokens double to $4/$12 — the cheap headline rate only holds on shorter contexts
Consumer access is a black box: xAI hasn't said which version grok.com, the mobile apps or Grok-in-X run, and reports conflict. If the exact model matters, use the API
Not the smartest model on this site: 46 on the Artificial Analysis index against GPT-6 Astra's 53 and GPT-6.1 Sol's 52, and on CursorBench 4.0 Anthropic reports 57.8% for Claude Opus 5.5 versus xAI's 46.3% for 4.7

Heads-Up
xAI hasn't said which version grok.com, the mobile apps and Grok-in-X run — reports conflict, so this page doesn't guess. grok-imagine-image-quality retires Nov 2; move to grok-imagine-image-2.0. Grok 5 has no announced date.
Milestone
Artificial Analysis rescaled its Intelligence Index to v4.3.2. On the new scale Grok 4.7 scores 46, up from 4.6's 44 — behind GPT-6.1 Sol (52) and GPT-6 Astra (53). Older scores aren't comparable.
