At its I/O developer conference, Google today announced the launch of PaLM 2, its newest large language model (LLM). PaLM 2 will power Google’s updated Bard chat tool, the company’s competitor to OpenAI’s ChatGPT, and function as the foundation model for most of the new AI features the company is announcing today. PaLM 2 is now available to developers through Google’s PaLM API, Firebase and on Colab.
Google, similar to OpenAI, didn’t provide a lot of the technical details about how it trained this next-gen model, including parameter counts (PaLM 2 is a 540-billion parameter model, for what it’s worth). The only technical details Google provided here are that PaLM 2 was built on top of Google’s latest JAX and TPU v4 infrastructure.
