Cursor’s new coding model Composer 2 is here: It beats Claude Opus 4.6 but still trails GPT-5.4

Cursor, a San Francisco AI coding platform from startup Anysphere valued at $29.3 billion, has launched Composer 2, a new in-house coding model now available inside its agentic AI coding environment, and it offers drastically improved benchmarks from its prior in-house model.It's also launching and making Composer 2 Fast, a higher-priced but faster variant, the default experience for users.Here's the cost breakdown:Composer 2 Standard: $0.50/$2.50 per 1 million input/output tokens Composer 2 Fast: at $1.50/$7.50 per 1 million input/output tokensThat's a big drop from Cursor's predecessor in-house model, Composer 1.5, from February, which cost $3.50 per million input tokens and $17.50 per million output tokens; Composer 2 is about 86% cheaper on both counts. Composer 2 Fast is also roughly
