Meta Launches Muse Spark 1.3 Max with Stronger Coding and Agentic Capabilities

9 月 5 日，Meta 首席 AI 官、Scale AI 创始人 Alexandr Wang 正式公开发布 Muse Spark 1.3 Max，将模型推理等级设为最高档 max。他称新版本在编码与智能体任务上的表现明显更强，并强烈建议已经用过 Muse Spark 1.3 High 或 1.3 XHigh 的用户也再试一次 Max 版本。

已确认

• 发布前已完成安全测试，之后才开放体验。
• 可通过 Muse Code CLI 工具和 Meta Model API 使用，Wang 给出了一条 curl 安装命令，支持终端直接安装。
• Meta 官方账号同步宣布 max reasoning 模式上线，卖点为「前沿性能、非前沿价格」，并展示 Meta 超级智能实验室的能力演示。

为什么重要

• 这是 Meta 在编码与 Agent 赛道上的最新动作，直接对标以强推理与编码见长的竞品模型；定价策略上强调性价比，可能加剧前沿模型价格竞争。
