A free model just appeared in Cursor (and it’s really good at code)

Summary

A new anonymous AI model called Sonic has emerged in the developer ecosystem, offering free access across multiple coding tools like Cursor, Klein, and Rue Code. Specifically designed for agentic coding and development tasks, the model is notable for its speed, performance with tool calls, and wide availability. While the model's origin was initially uncertain, it was ultimately revealed to be from XAI, and it appears primarily focused on helping developers solve code problems, build applications, and manage projects. The model represents an intriguing addition to the AI coding landscape, providing developers with a powerful, freely accessible coding assistant.
