gLM is an AI model developed by Harvard University (United States), first published in April 2023. It works in the biology domain, on tasks such as protein or nucleotide language model (plm/nlm).

Training it took an estimated 2.3×10²⁰ FLOP of compute (estimation method: hardware). The model has 1,000,000,000 parameters. Training ran on NVIDIA A100.

Access: Open weights (non-commercial). Its weights are openly available. It is built on top of ESM2-650M. Epoch AI rates the confidence of this record as likely.
