# Meta 发布 Muse Code 和 Muse Spark 1.2：聚焦编码智能体

## AI 点评

> 这次发布最值得关注的是 Meta 把模型和编码智能体工具链捆绑推出，说明长序列 agentic 调用正在成为评估模型的新标准。对 AI 工程师来说，与其只盯基准测试，不如实际测一测仓库级生成的连贯性。

## 速览

Meta 发布 Muse Code 与 Muse Spark 1.2。Muse Spark 1.2 专注编码，提升代码生成、复杂调试、代码库理解和端到端工作流，与 Muse Code 共同训练以优化编码表现。训练大幅增加编码任务计算量，并扩展环境多样性，覆盖仓库级生成和大型项目等长周期任务。Simon Willison 评论称，这再次证明长序列 agentic 工具调用是当前模型最重要的特性。

## 关键点

- Muse Spark 1.2 聚焦编码，改进代码生成、复杂调试、代码库理解和端到端开发工作流。
- 与 Muse Code 共同训练，通过 harness 轨迹优化和子代理提升编码可用性。
- 训练覆盖仓库级生成、大型端到端项目和自动研究等长周期任务。
- Simon Willison 指出长序列 agentic 工具调用是模型最重要的特性。

Introducing Muse Code and Muse Spark 1.2 Yet more evidence that the most important characteristic of any model these days is long-sequence agentic tool calling. Meta shipped their own coding agent as part of getting that to work! Muse Spark 1.2 is a coding-focused update to Muse Spark 1.1, with improvements in code generation, complex debugging, codebase understanding, and end-to-end developer workflows. In Muse Spark 1.2, we significantly scaled up training compute on coding tasks while expanding training environment diversity. The model also maintains its strength in other key areas like general agents. [...] We co-trained Muse Spark 1.2 with Muse Code to ensure the model exhibits its best performance and coding usability when paired together. The training included rejection sampled harness trajectories and recipe optimizations for goals, compaction, and subagents, alongside the integration of the Muse Code toolset to maximize harness compatibility. [...] Muse Spark 1.2 was extensively trained on long-horizon coding tasks, including whole-repository generation, large end-to-end projects, and auto-research. Here's a pelican riding a bicycle SVG produced by Muse Spark 1.2: You can see the Spark 1.1 pelican from 9th July here. I think the 1.2 pelican is a small but material improvement.
