xAI launches Grok 4.7, twice as fast as Grok 4.6 at the same price

xAI 发布 Grok 4.7，主打编码与知识工作

Grok 4.7 uses a larger base model and a longer RL run on harder, multi-hour tasks. It scores 46.3% on CursorBench 4.0, ahead of GPT-5.6 Sol Max (41.7%) but behind Fable 5.1 Max (51.8%). Pricing stays at $2/$6 per million input/output tokens, same as Grok 4.6, with double the speed. Safety stack is new: only 3.3% of risky cyber prompts get through, and it hits 62.4% on LatchBio's biosafety benchmark. Available today in Cursor, Grok Build, and the API.

Why it matters: xAI drops Grok 4.7 targeting coding and knowledge work, hitting 46.3% on CursorBench 4.0 — above GPT-5.6 Sol Max but behind Fable. Concrete benchmark and training details clear all three HKR axes. Held below 85 because the post doesn't disclose model size, architecture changes...
