Zhipu AI released GLM-5.1, an open-weight 754-billion parameter agentic model capable of sustaining autonomous execution for up to eight hours. The model achieved state-of-the-art performance on SWE-Bench Pro and can iteratively rethink its coding strategies across hundreds of iterations, enabling it to handle complex long-horizon tasks. The launch, announced between April 7-9, positions the model as a significant advancement in autonomous AI agents capable of extended independent operation.
