Wu Dao 2.0 is an AI model developed by Beijing Academy of Artificial Intelligence / BAAI (China), first published in May 2021. It works in the multimodal, language, vision and image generation domain, on tasks such as image captioning, chat, image generation and 4 more. It counts among the frontier models: the systems trained with the most compute of their moment.

Training it took an estimated 1.5×10²⁴ FLOP of compute (estimation method: operation counting). The model has 1,750,000,000,000 parameters. It was trained on roughly 4.9T datapoints. The compute alone is estimated at $3M in 2023 dollars.

Access: API access. Its weights are not openly released. Epoch AI rates the confidence of this record as speculative.
