Cursor@cursor_aiIntroducing Composer 2.5, our most powerful model yet. It's more intelligent, better at sustained work on long-running tasks, and more reliable at following complex instructions. For the next week, we’re doubling the included usage of the model.Opens with an announcement
Cursor@cursor_aiGPT-4.1 is enabled for all Cursor users! We're launching it for free for the time being, to let people get a feel for the model. Curious to hear what you think. We don't yet recommend it as a default.Opens with an observation
Cursor@cursor_aiTogether with SpaceXAI, we’re training a significantly larger model from scratch, using 10x more total compute. With Colossus 2’s million H100-equivalents and our combined data and training techniques, we expect this to be a major leap in model capability.Opens with an observation
Cursor@cursor_aiClaude Opus 4.5 is now available in Cursor! It's 3x cheaper than Opus 4.1 with better performance. Try it out at Sonnet pricing until December 5th.Opens with an observation
Cursor@cursor_aiWe improved Composer by scaling training, generating more complex RL environments, and introducing new learning methods. For example, we use text feedback during RL to learn faster by assigning credit in rollouts spanning hundreds of thousands of tokens.Opens with an observation
Cursor@cursor_aiWe were able to significantly improve the model quality and cost to serve. These quality improvements come from our first continued pretraining run, providing a far stronger base to scale our reinforcement learning.Opens with an observation
Cursor@cursor_aiWe recently launched Composer 2, a frontier model with high limits. Then, with cloud, we gave agents their own computers so they can work truly autonomously. And now with Cursor 3, we’re releasing a new interface to collaborate with agents on software. t.coOpens with an observation
