New comprehensive Grok 4.7 deep-dive published: xAI's frontier coding and knowledge work model with new safeguard stack, longer RL training, and domain-specific dominance at $2/$6 pricing.
On September 21, 2026, xAI released Grok 4.7 — a new frontier model built on a larger base with a longer reinforcement learning run weighted toward multi-hour tasks. At $2/$6 per million tokens (same as Grok 4.6), it scores 46.3% on CursorBench 4.0 (vs. 40.4% for 4.6), 71.0% on DeepSWE v1.1, 64.0% on EEBench, and 19.6% on Harvey Legal Agent, while introducing an entirely new safeguard stack that tops LatchBio's biosafety benchmark at 62.4% and achieves 3.3% dual-use pass rate on HackerBench v0.3. With 500K context, configurable reasoning up to xhigh, and encrypted reasoning on the Responses API, Grok 4.7 positions xAI as a serious contender in the frontier coding and knowledge work race.
One new research article published: Grok 4.7 deep-dive covering xAI's new larger base model, domain-specific dominance (legal, clinical, engineering), the entirely new safeguard stack, multi-hour agent optimization, and the unprecedented September 21-22 convergence of four frontier releases.
On September 21, 2026, xAI released Grok 4.7 — a new larger base model trained with extended RL on multi-hour tasks, delivering frontier coding and knowledge work performance at $2/$6 per million tokens, with the strongest safeguard stack xAI has built and best-in-class results on legal, clinical, and biosafety benchmarks.
One new research article published: xAI Grok 4.6 and Grok Bot — the 1.5T parameter agentic coding stack with persistent cloud teammates, matching GPT-5.6 Sol on the AA Intelligence Index.
xAI released Grok 4.6 (1.5T parameters, 500K context, frontier coding benchmarks) and Grok Bot (persistent cloud AI teammates) in mid-August 2026. Covers the coordinated release, training methodology (SFT trajectory regeneration + agentic RL), benchmark results matching GPT-5.6 Sol on AA Intelligence Index, Grok Bot's persistent cloud computer architecture, Microsoft Foundry integration, and the Grok 4.7 pipeline.
One new research article published: comprehensive deep-dive on xAI and Cursor's Grok 4.5 — a 1.5T-parameter MoE model trained on trillions of tokens of real developer workflows, achieving 4.2× token efficiency on SWE-bench Pro at $2/$6 pricing.
xAI and Cursor jointly release Grok 4.5 on July 8, 2026 — a 1.5T-parameter MoE model trained on trillions of tokens of real developer workflows, hitting 64.7% on SWE-bench Pro, 83.3% on Terminal-Bench 2.1, and 62.0% on DeepSWE 1.0, all at $2/$6 per million tokens with a 500K context window.
