Fable is back in Cursor. This post shares a pattern using Fable as an orchestrator with Composer 2.5 as workers for efficient AI-assisted coding, along with tips for long-horizon cloud agents and rotating models.

Fable 5 integrates with Composer 2.5 Fast for enhanced AI code generation capabilities.

Muennighoff announces work on a much better composer model, scaling to Opus/GPT-size, training from scratch, and going beyond coding, as part of Cursor's collaboration with SpaceX.

Bobby Prince, the composer for classic video games Doom, Wolfenstein 3D, and Duke Nukem 3D, has passed away.

Cursor AI describes its recursive agent system for scaling training of its Composer model, using a fleet of agents that self-manage and alert humans when issues arise. The system enables parallel experiments and accelerates research, treating researcher time as the scarcest resource.

Tod Machover, MIT professor and music tech pioneer, receives the George Peabody Medal for his contributions to music and technology, recognizing his work in participatory opera, AI, and creative technologies.

Developer praises Composer 2.5 for its planning, scaffolding, and speed in getting tasks done.

User Danny Limanseta praises Composer 2.5 for its speed and effectiveness, claiming it has replaced GPT 5.5 and Opus 4.7 for planning and development.

Cursor announces Composer 2.5, an upgraded AI model for coding that is more intelligent and reliable, partially trained on Colossus 2. Usage is doubled for the next week.

Cursor AI announces Composer 2.5, their most powerful model yet, with enhanced intelligence, better sustained work on long tasks, and improved instruction following; they are doubling included usage for a week.
