Flan-PaLM 540B is an AI model developed by Google (United States), first published in October 2022. It works in the language domain, on tasks such as language modeling/generation, question answering and mathematical reasoning. It counts among the frontier models: the systems trained with the most compute of their moment.

Training it took an estimated 2.5×10²⁴ FLOP of compute (estimation method: reported,hardware). The model has 540,000,000,000 parameters. It was trained on roughly 1.4B datapoints. Training ran on 512 Google TPU v4 for about 37 hours.

Access: Unreleased. Its weights are not openly released. It is built on top of PaLM (540B). The reference paper has 4,129 citations. Epoch AI rates the confidence of this record as confident.
