xAI launches Grok 4.7 with major benchmark gains at unchanged price and speed
xAI officially launched Grok 4.7 on September 22, calling it its strongest coding and knowledge-work model to date, with significant improvements at the same price and speed as Grok 4.6. The model is available in Grok Build, Cursor and other products, and the model card shows major benchmark gains, but third-party early tests aggregated by TheAIGRID (such as ValsAI) suggest a gap with some community expectations; real-world reception remains to be seen.
Confirmed
- Announcement and availability: a Reddit post relayed xAI's official news page on September 21; the official SpaceXAI account formally announced the release on September 22, with Elon Musk repeatedly amplifying it. Available in Grok Build (Low/Medium/High/Extra High reasoning levels) and Cursor; grok update upgrades the CLI.
- Pricing unchanged from 4.6: $2 per million input tokens, $6 per million output tokens; the company also claims twice the speed at half the price of comparable models.
- Improvements: a new, larger base model with longer reinforcement-learning training on multi-hour tasks, better self-verification and long-context retention, native understanding of the Grok Bot system, and what xAI calls its strongest safety guardrails to date. Team member haozhuwang noted training on longer-horizon problems.
- Benchmarks (model card, shared by Musk): Terminal-Bench 20.3% → 38.0%; SWE-Marathon 31.9% → 46.0%; CursorBench 4.0 40.4% → 46.3%; large gains on Harvey legal benchmarks and HealthBench Pro.
- Official 4.6 vs 4.7 demos: building an open-world city game and building Age of Empires II with AI.
- Real-world case: Box's Agent preview used Grok 4.7 on a $2M insurance claim, flagging $82,000 in duplicate invoices.
- Team and ecosystem: team member aksheyd cited extensive harness polish and partnerships with top engineering teams; early users praised coding, engineering and 3D performance at high TPS in Grok Build and Cursor.
- NVIDIA congratulated the launch and said it provides accelerated compute for xAI.
- Early third-party feedback: TheAIGRID aggregated posts noting ValsAI and other testers found overall results below community expectations.
Unconfirmed
- @AlexFinn's claim that Grok 4.7 is an "agentic model" trained specifically for Grok Bot to do knowledge work comes from a single account and is not in the official announcement (though native Grok Bot support is confirmed).
- @Polymarket's "twice the speed, half the price" framing conflicts with official pricing parity with 4.6; the official announcement should be treated as authoritative.
- Pre-launch double-speed-tier pricing reported by @markk was not mentioned in the official announcement.
Why it matters
- Same price and speed plus near-doubled Terminal-Bench and large CursorBench/legal gains directly boost Grok's cost-performance edge in agent, terminal and professional knowledge-work scenarios.
- Emphasis on multi-hour tasks, self-checking and native Grok Bot integration, plus Box's claims-audit demo, signals xAI is betting on full-agent workflows for real work.
- Commenters flagged its electronics-engineering results—SpaceX's engineering data may be a unique training advantage.
- The gap between official messaging and early third-party tests suggests real-world performance beyond formal benchmarks will decide its competitiveness.
