Decision summary
- New API calls -> grok-4.7
- Prompts over 200K tokens -> double the rate on the 4.7 card
- Twice the output speed -> Grok 4.7 Fast in Cursor or Grok Build, at twice the price
- Existing grok-4.6 pin -> replay, then switch

Decision axes: Best for · Access · Context · List price
Reasoning
4.7 defaults to high and offers xhigh. Confirm 4.6's default on its own card.
Coding
4.7 is the current coding ID. 4.6 scores use older bench names.
Multimodal
Text and image in, text out, on both.
Speed
xAI says 4.7 matches 4.6's speed. Fast is a separate Cursor and Grok Build offer.
Enterprise
The X Subscription is how new customers buy Grok and Cursor. The API ID is still grok-4.7.

How they compare
Criterion-by-criterion notes from the catalog—not a ranking. Validate on your own gold set.
| Criterion | Grok 4.7 | Grok 4.6 |
|---|---|---|
| Best for | New Grok coding and knowledge-work traffic. | Pinned grok-4.6 calls during a replay. |
| Access | API ID grok-4.7. Released September 21, 2026. Fast variant only in Cursor and Grok Build. | API ID grok-4.6. Released August 12, 2026. Superseded in this catalog by Grok 4.7. |
| Context | 500,000 tokens. Text and image in, text out. | 500,000 tokens. Text and image in, text out. Function calling, web and X search, and code execution are on the 4.6 docs. |
| List price | At or under 200K tokens: $2 / $0.50 cached / $6. Above 200K: $4 / $1 / $12. xAI says this matches Grok 4.6. | xAI's 4.7 launch says 4.7 keeps 4.6's price and speed. Keep the pin on 4.6 only if you still need that exact ID. |
| Controls | Reasoning low, medium, high (default), and xhigh. | Reasoning from low through xhigh. Confirm the default on the 4.6 card rather than copying 4.7's high default. |
| Operational risk | Launch-post scores are vendor-reported and use different bench versions than the Grok 4.6 post. Do not subtract them. | Older comparison pages that treat 4.6 as the current flagship are stale. Grok 4.7 is the current ID. |
Key insights
Concrete technical or product signals.
- Same published price is not the same model. 4.7 is a new, larger base model with a longer reinforcement-learning run.
- Grok 4.7 Fast is a separate offer inside Cursor and Grok Build, at twice the output speed and twice the price.
Use cases
Where this shines in production.
- Moving a grok-4.6 pin
- Quoting Grok API cost
Limitations & trade-offs
What to watch for.
- CursorBench 4.0 on the 4.7 post is not CursorBench v3.2 on the 4.6 post.
- This page does not award a benchmark winner.
Who should not choose this?
Signals that this pair is the wrong default.
- Do not compare CursorBench 4.0 with CursorBench v3.2 as if they were one test.
- Do not budget Fast at the standard output rate.
- Do not keep 4.6 as the recommended ID.
Final recommendation
What to do after reading the table.
Repoint grok-4.6 clients to grok-4.7 after one replay.
FAQ
Is Grok 4.7 better than Grok 4.6?
Neither Grok 4.7 nor Grok 4.6 is a universal winner. Use the comparison table and the choose-when notes, then validate on your workload.
Which is cheaper: Grok 4.7 or Grok 4.6?
Listed unit prices: Grok 4.7 At or under 200K tokens: $2 / $0.50 cached / $6. Above 200K: $4 / $1 / $12. xAI says this matches Grok 4.6; Grok 4.6 xAI's 4.7 launch says 4.7 keeps 4.6's price and speed. Keep the pin on 4.6 only if you still need that exact ID. A lower listed unit price is not the same as a lower total workload cost—tokens, session minutes, caching, introductory rates, and add-on modes can reverse the ranking. Confirm live rates on each vendor’s official page.
Can I use both Grok 4.7 and Grok 4.6?
Yes. Many teams keep both and route by constraint. Use Grok 4.7 for New Grok coding and knowledge-work traffic, and Grok 4.6 for Pinned grok-4.6 calls during a replay. Confirm vendor terms before mixing them in one production workflow.
