xAI releases Grok 4.6, leads on agentic task efficiency
What happened
Grok 4.6 在 Grok 4.5 的基础上，专门训练了模型处理长链条任务的能力，比如做研究、分析信息、跨代码库工作，或者把一个想法直接做成能用的应用。在 AA 智能指数这个综合跑分上，它和 GPT-5.6 Sol 打平，都是 61 分；在 DeepSWE 1.1 这个软件工程测试里，分数从 4.5 的 54% 跳到了 65.9%。xAI 说，任务...

Grok 4.6 scores 61 on the Artificial Analysis Intelligence Index, a 5-point gain over Grok 4.5, matching GPT-5.6 Sol (max) and trailing only Anthropic's Claude Opus 5 (63) and Claude Fable 5 (62). It shines on agentic tasks: GDPval-AA v2 Elo of 1753, behind only Claude Opus 5; 50.7% on 𝜏³-Banking and 88.4% on Terminal-Bench v2.1, both top-tier. Pricing stays at $2/$6 per 1M input/output tokens, over 60% cheaper than Claude Opus 5 and GPT-5.6 Sol. On AA-Briefcase, a long-horizon knowledge-work benchmark, it scores Elo 1577 (Fable 5-tier) but finishes tasks in ~53 turns and ~0.5B input tokens vs. ~103 turns and ~2.0B for Claude Opus 5, giving it a large cost edge. Context window remains 500k tokens; cache-hit pricing rose from $0.3 to $0.5 per 1M tokens.
- AI HOT (Curated Pool)PickxAI releases Grok 4.6, focused on long-running agent capabilities
Grok 4.6 builds on Grok 4.5 with a focus on long-running agents that can research, analyze, code, or turn an idea into a working app across many steps. It matches GPT-5.6 Sol on the AA Intelligence Index at 61, and jumps from 54% to 65.9% on DeepSWE 1.1. xAI reports the model shows more self-testing and verification on longer trajectories. Pricing is $2/M input tokens and $6/M output tokens, with a fast variant at double the price. Available today in Cursor and Grok Build, with 2x included usage for the first week.
