tetsuoai · x · 2026-09-22
- xAI released Grok 4.7, its most capable model for coding and knowledge work, built on a larger new base model with a longer RL run focused on multi-hour tasks, better self-verification, and longer context handling.
- Priced identically to Grok 4.6 at $2/M input and $6/M output tokens — half the price of GPT-5.6 Sol ($4/$20) and Fable 5.1 Max ($10/$50), claimed twice as fast.
- Benchmarks: 46.3% on CursorBench 4.0 (vs 40.4% for 4.6), 64.0% on EEBench, 38.0% on Terminal-Bench 4.0 (vs 20.3%), 19.6% on Harvey Legal Agent Benchmark where GPT-5.6 Sol scores just 2.5%, and 56.7% on HealthBench Professional.
- Ships with the company's best-calibrated safeguards to date.
