GLM-4.1V-Thinking is an AI model developed by Z.ai (Zhipu AI) and Tsinghua University (China), first published in August 2025. It works in the multimodal, vision and language domain, on tasks such as language modeling/generation, question answering, visual question answering and image captioning.
Training it took an estimated 9.2×10²³ FLOP of compute (estimation method: operation counting). The model has 9,000,000,000 parameters.
Access: Open weights (unrestricted). Its weights are openly available. It is built on top of GLM-4-9B-0414. Epoch AI rates the confidence of this record as likely.
