SpaceXAI发布Grok 4.6：500K上下文，针对长时智能体与编码优化

精选理由

Grok 4.6来了，500K上下文还加了xhigh推理，跑长任务更稳。编码还是短板，但智能体场景可以试试。

AI 摘要

SpaceXAI于8月12日发布Grok 4.6，这是基于Grok 4.5的后训练升级而非更大基础模型。Grok 4.6在Artificial Analysis Intelligence Index上以61分追平GPT-5.6 Sol Max，支持500K上下文并新增xhigh推理等级。定价保持每百万token输入2美元、输出6美元。不过在编码基准上仍然落后于竞品。

SpaceXAI Releases Grok 4.6: A 500K-Context Frontier Model Tuned for Long-Running Agents, Coding, and Knowledge Work

SpaceXAI released Grok 4.6 on August 12, 2026 — a post-training upgrade over Grok 4.5, not a larger base model. It ties GPT-5.6 Sol Max at 61 on the Artificial Analysis Intelligence Index, ships 500K context and a new xhigh reasoning level, and holds pricing at $2/$6 per million tokens. The coding benchmarks are where it still loses.
