Composer 2: What is new and Compares with Claude Opus 4.6 & GPT-5.4

Cursor’s Composer 2 is the company’s newest agentic coding model, announced on March 19, 2026. Cursor describes it as “frontier-level at coding,” built for low-latency software work, and available directly inside Cursor with a standalone usage pool for individual plans. The launch also introduced a faster variant with the same intelligence, plus a new pricing structure designed to make agentic coding more affordable than many general-purpose frontier models. Composer 2 matters because it reflects a broader shift in AI software development: the value is no longer just raw model intelligence, but the combination of speed, long-horizon task handling, tool use, and cost efficiency. Cursor’s own framing is explicit: the model is optimized for agentic coding, can handle challenging tasks that require hundreds of actions, and was trained to preserve critical context across long-running workflows.
