[Cursor Launches Composer 2.5, Calling It Their 'Most Powerful Model Yet'] AI startup Cursor announced on the X platform that it has launched Composer 2.5, describing it as their 'most powerful model yet.' Cursor stated that the Composer 2.5 model is smarter, better at handling long-duration tasks, more reliably follows complex instructions, and is 10 times more efficient than models with similar capabilities. The model is built on the same open-source foundation Moonshot as Composer 2, utilizing Kimi K2.5. Cursor is collaborating with SpaceXAI to train a larger-scale model from scratch, leveraging 10 times the total computational power, supported by Colossus 2's million H100-equivalent compute capacity, along with the data and training technologies from both parties. Usage quotas for the model will double in the coming week.
