Composer 2.5

Composer 2.5 is a coding-focused agent model from Cursor, released on 18-05-2026 and made available directly inside Cursor. It improves over Composer 2 in intelligence, behavior, sustained long-running work, complex instruction following, communication style, and effort calibration. Cursor says Composer 2.5 is built on the same open-source checkpoint as Composer 2, Moonshot’s Kimi K2.5, and was improved through scaled training, harder reinforcement-learning environments, targeted textual feedback, synthetic coding tasks grounded in real codebases, and training-stack changes such as sharded Muon and dual-mesh HSDP. It is a closed product model served through Cursor, focused on coding, agent workflows, tool use, repository-level tasks, and software-development collaboration.
