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 57% cheaper than Composer 1.5.There’s also discounts for “cache-read pricing,” that is, sending some of the same tokens in a prompt to the model again, of $0.20 per million tokens for Composer 2 and $0.35 per million for Composer 2 Fast, versus $0.35 per million for Composer 1.5.It also matters that this appears to be a Cursor-native release, not a broadly distributed standalone model. In the company’s announcement and model documentation, Composer 2 is described as available in Cursor, tuned for Cursor’s agent workflow and integrated with the product’s tool stack. The materials provided do not indicate separate availability through external model platforms or as a general-purpose API outside the Cursor environment.Cursor is pitching long-horizon coding, not just better completionsThe deeper technical claim in this release is not merely that Composer 2 scores higher than Composer 1.5. It is that Cursor says the model is better suited to long-horizon agentic coding.In its blog, Cursor says the quality gains come from its first contin …
