Grok 4.7
SpaceXAI's best model to date — a larger Grok trained on a longer, harder reinforcement-learning run plus SpaceX engineering data, at Grok 4.6's price and speed
Grok 4.7
SpaceXAI • September 2026
Training Data
Adds SpaceX data: Starlink telemetry, manufacturing records, and engineering failure logs
Grok 4.7
September 2026
Parameters
2.1 trillion (claimed by Musk)
Training Method
Longer RL run on a harder task mix weighted toward problems that take many hours
Context Window
500,000 tokens
Knowledge Cutoff
Not disclosed
Key Features
500K Token Context • Self-Verification • New Safeguard Stack • Fast Variant (2x speed)
Capabilities
Coding: Outstanding (71.0% DeepSWE v1.1)
Knowledge Work: Outstanding
Safety: Strong (xAI's best jailbreak resistance)
What's New in This Version
Improves on Grok 4.6 at the same price ($2/$6 per 1M tokens) and speed — 71.0% on DeepSWE v1.1 vs 65.9% — checks its own work more often, and is xAI's strongest model yet on refusals and jailbreak resistance; launched September 21 after at least five public delays
