Architectural Profile & Capabilities

AA Intelligence Index: 61 (matches GPT-5.6 Sol), GDPval-AA v2: 1753 Elo, CursorBench v3.2: 69.9%, DeepSWE v1.1: 65.9%, FrontierCode v1.1 Extended: 61.3%, APEX-Agents: 57.5%, Terminal-Bench v3.0: 26%, APEX-SWE: 56.4%, AA-Briefcase: 1577 Elo, Harvey LAB: 15.8%, SWE-bench Verified (Vals): 95.60%, GPQA Diamond: 94.9%, HLE: 42.9%, AA Coding Index: 76.8, AA Agentic Index: 58.7, AA Non-Hallucination Rate: 65.7% | xAI's current frontier model (released Aug 12, 2026; knowledge cutoff Feb 1, 2026). Builds on Grok 4.5 with a focus on long-running agents and interactive/visual work. Matches GPT-5.6 Sol on the AA Intelligence Index composite (61). **Domain-leading strengths: knowledge work and professional tasks (GDPval-AA v2 #1 at 1753 Elo), legal agentic work (Harvey LAB 15.8% — 6.3× Sol), in-editor coding (CursorBench 69.9%), long-horizon agentic tasks (APEX-Agents 57.5%).** SWE-bench Verified 95.60% (#4). 500K context. $2/$6 per MTok (unchanged from 4.5), doubling past 200K tokens. **Caveats: trails GPT-5.6 Sol on DeepSWE v1.1 (65.9% vs 73%) and Terminal-Bench v3.0 (26% vs 34.6%) — the launch post skipped these losses; 500K context smaller than peers' 1M; all launch benchmarks vendor-reported, no independent replication yet; pricing doubles past 200K prompt tokens.**

Architecture Type: Dense Transformer

Standard dense autoregressive transformer architecture with full-attention mechanisms.

Recommended Workloads & Primary Use Cases

Everyday reasoning

Fast problem solving

Operational Caveats & Boundaries

•Extended context pricing applies above 200K tokens: $4/M in, $12/M out.

ARMES Zero Data Retention

Calls to Grok 4.6 are routed through strict Zero Data Retention inference channels. Prompts and outputs are never stored, indexed, or monitored by xAI.
