xAI releases Grok 4.5 trained on real developer workflows · 1 source tracked

By PulseAugur Editorial · [1 sources] ·

xAI has released Grok 4.5, a 1.5-trillion-parameter Mixture-of-Experts model trained on real developer interaction data from the Cursor IDE. This unique training approach, which includes multi-file diffs and debugger sessions, aims to improve the model's ability to assist developers in agentic workflows. While Grok 4.5 offers fast serving speeds and a broad training mix beyond just coding, it has a reduced context window compared to its predecessor and faced benchmark contamination issues due to an accidental inclusion of Cursor's codebase.

IMPACT Sets new SOTA on developer workflow tasks; may accelerate agentic AI adoption.
