I went down the cloud console rabbit hole to play with it. Only the bison model was available (of the non-descriptively named gecko, otter, bison, unicorn models). For innocuous prompts I got this error: "The response is blocked because the input or response potentially violates our policies. Try rephrasing the prompt or adjusting the parameter settings. Currently, only English is supported."

Where it did respond, I liked the quality. It was comparable to the GPT-3.5 API. Perhaps a little better even.
