PaLM (Google) has 540 billion parameters and was opened via API in March 2023.

Summary

Google's PaLM model is a 540-billion-parameter system that moved from internal research to being accessible to outside developers through an API starting in March 2023. This anchors two important facts for the system: the scale of compute and resources that class of model demands, and the point in time when that capability became available beyond Google's own team.
