Grok 4.7 rolls out at same price with big gains on long-horizon tasks

xAI has released Grok 4.7, with multiple community users confirming the new model is live and reportedly appearing in the xAI API, corroborating the launch news. Taken together, the leaks suggest the new version delivers significant benchmark and capability improvements at unchanged pricing—the most notable story of this release cycle.

Confirmed

• Grok 4.7 has shipped and is available: users including @DanielLockyer confirmed the new version is live, and @iamfakhrealam reports, citing LuminaBench, that Grok 4.7 has appeared in the xAI API.
• Pricing stays flat versus 4.6: $2/M input, $6/M output, plus a double-speed tier at twice the price (via @markk).
• Upgrade direction: a larger base model with longer RL training; officials say the new model can persist longer on hard multi-hour tasks and check its results more carefully (via @nimaowji, @markk).
• Benchmark performance: Terminal-Bench improved from 20.3% to 38.0% (via @markk, noted as unverified in the post).

Not Yet Confirmed

• Most posts are leaks from third-party accounts, and early posts (@markk, @koltregaskes) explicitly noted they were unverified by official xAI channels; later community confirmations and the API sighting boost credibility, but a full official statement from xAI and detailed benchmark data are still pending.

Why It Matters

• Faster performance at the same price, plus a near-doubling on Terminal-Bench, directly improves Grok's cost-performance competitiveness in agent and terminal task scenarios.
• The emphasis on multi-hour long-horizon tasks and self-checking signals that xAI is positioning agent scenarios as its main competitive front.
