Open-Source Agent Framework "Conductor" Reaches 1.0

Conductor, a lightweight Python framework for building AI agents with explicit state machines, has officially launched version 1.0 after 18 months of development. Unlike black-box agent frameworks, Conductor requires developers to define discrete states and transitions, which has proven to produce more reliable and debuggable agents for production environments. The project has gained 15K GitHub stars and backing from several AI safety researchers.

Cursor Editor Adds "Shadow Mode" for Training Custom Models

Cursor unveiled Shadow Mode, which records developers' coding patterns and decisions without interfering with their workflow, creating training datasets for fine-tuned organization-specific models. The feature runs entirely locally and gives developers granular control over what data is collected. Three enterprises in the private beta reported 35% better suggestion acceptance rates after two weeks of shadow training.
