## AI 摘要

Meta 发布 Muse Spark 1.3，重点提升智能体与编码任务表现并聚焦真实可用性。模型可在单线程中跨多个工作流维持更长程的任务，更主动与用户协作，会提出澄清问题、标记卡住状态并在关键操作前确认；对自身局限的校准更好以减少幻觉结果。内部对比显示相比 Muse Spark 1.2 工具调用减少约 20%，token 消耗减少约 25%。

## 正文

We’re excited to release Muse Spark 1.3 with improved performance on agentic and coding tasks, and a focus on real-world usability.

Key capabilities:
→ Sustains longer-horizon work across multiple workflows in a single thread
→ More actively collaborates with users: it asks clarifying questions, flags when it's stuck, confirms before consequential actions
→ Better calibrated on its own limits instead of hallucinating outcomes
→ ~20% fewer tool calls and ~25% fewer tokens vs. Muse Spark 1.2 in internal comparisons
