Same $2/$6 Standard pricing. CursorBench 4.0 rises from 40.4% to 46.3%, Terminal-Bench 4.0 from 20.3% to 38.0%, DeepSWE v1.1 from 65.2% to 71.0% (high effort), GDPval from 1,605 to 1,695, and AA Briefcase v1.1 from 1,546 to 1,657.
Release Summary
SpaceXAI's most capable model for coding and knowledge work, succeeding Grok 4.6 at the same $2/$6 per million token list price. A new, larger base with a longer RL run on multi-hour tasks scores 46.3% on CursorBench 4.0 (xhigh) versus 40.4% for 4.6, 38.0% on Terminal-Bench 4.0 versus 20.3%, and 71.0% on DeepSWE v1.1 at high effort. It leads the announcement table on EEBench (64.0%) and Harvey Legal Agent (19.6%) versus GPT Sol 5.6 and Claude Fable 5.1, and sits close to Fable 5.1 on AA Briefcase v1.1 (1,657 vs 1,678) and GDPval (1,695 vs 1,735). The EEBench bar chart in the same post puts GPT Astra 6 ahead at 69.3%. Available today in Cursor, Grok Build, the Grok API as grok-4.7, and third-party harnesses. Fast doubles output speed at 2x the price. 500K context, knowledge cutoff May 2026.
