# Grok 4.6 ![Grok 4.6 announcement header](https://x.ai/images/news/grok-4-6-og.png) > **Quick answer:** Grok 4.6 is xAI's August 2026 flagship model, focused on agentic coding and long-horizon task execution. It reports DeepSWE 65.9%, APEX-Agents 57.5%, AA Briefcase 1577 Elo, GDPVal-AA 1753 Elo, and an AA Intelligence Index of 61 — priced at $2 input / $6 output per 1M tokens, with a faster variant available at 2x that price. ## What Grok 4.6 Is Grok 4.6 is xAI's incremental flagship release following Grok 4.5, announced August 12, 2026. The release is positioned around agentic coding and tool-use reliability rather than raw knowledge benchmarks — xAI's announcement leads with scores on agent-native evals like DeepSWE, APEX-Agents, CursorBench, and FrontierCode rather than static knowledge tests. The model is available through Cursor, xAI's Grok Build product, the xAI API, OpenRouter, Vercel AI Gateway, and Cloudflare Workers AI at launch — a distribution footprint aimed squarely at developer coding tools rather than consumer chat. ## Specifications | Field | Value | |---|---| | Organization | xAI | | License | Proprietary (API only) | | Release date | August 12, 2026 | | Modality | Multimodal | | Knowledge cutoff | February 2026 | ## Public Benchmark Scores | Benchmark | Score | Source | Date | |---|---|---|---| | [DeepSWE](/benchmarks/datacurve/deepswe) | 65.9% | xAI Grok 4.6 announcement | 2026-08 | | [APEX-Agents](/benchmarks/mercor/apex-agents) | 57.5% | xAI Grok 4.6 announcement | 2026-08 | | [AA Briefcase](/benchmarks/artificial-analysis/aa-briefcase) | 1577 Elo | xAI Grok 4.6 announcement | 2026-08 | | [GDPVal-AA v2](/benchmarks/artificial-analysis/gdpval-aa-v2) | 1753 Elo | xAI Grok 4.6 announcement | 2026-08 | | [CursorBench](/benchmarks/cursor/cursorbench) | 69.9% | xAI Grok 4.6 announcement | 2026-08 | | [FrontierCode (Extended)](/benchmarks/cognition/frontiercode) | 61.3% | xAI Grok 4.6 announcement | 2026-08 | | [APEX-SWE](/benchmarks/mercor/apex-swe) | 56.4% | xAI Grok 4.6 announcement | 2026-08 | | [Terminal-Bench 3.0](/benchmarks/stanford-laude-institute/terminal-bench-3) | 26% | xAI Grok 4.6 announcement | 2026-08 | xAI also reports an **AA Intelligence Index score of 61** — Artificial Analysis's composite of nine evaluations.
