code-as-action

开源的科研智能体 OpenAI4S，通过持久化内核运行真正的 Python/R 代码，结合 JSON 工具编排，让研究者可以用极低成本（豆包 ¥9.9/月）复现 Claude Science 级别的科研自动化。

Highlights three recent AI papers: SpatialClaw (training-free spatial reasoning via code), SkillWeaver (compositional skill routing with decompose-retrieve-compose pipeline), and PreAct (compiling agent runs into fast state machines for repeated tasks).

SpatialClaw is a training-free framework that uses code as an action interface to enable flexible, stateful spatial reasoning in vision-language models, achieving superior performance across diverse 3D/4D spatial reasoning tasks.
