#model-training

xAI’s next Grok foundation model is moving from training into fine-tuning at 1.5T parameters, three times the size of the current 0.5T production model. Musk says Cursor data was added and public release is 2 to 3 weeks away.

A March 29 r/singularity thread amplified Cursor's claim that Composer checkpoints can now be trained from live user interactions and shipped every five hours, with reward-hacking fixes treated as part of the story rather than an afterthought.
