Not really. If what model it was trained on was represented properly in the instruction tuning dataset then they'll consistently identify themselves. But it's not a given that that was the case for bard.

It seems that Bard's version is only specified in the prompt, and it doesn't have a strong sense of identity. For me it's pretty reliable:

1. ask it what PaLM 2 is (to pollute the context) 2. ask it whether it's based on PaLM 2 (it will tell you - yes, sure)
