The real heated contest here amongst the top AI labs is to see who can come up with the most confusing product names.
Not quite. "2.0 Flash" is also called 2.0. The "Pro" models are the full models. But, I love how they have both "gemini-exp-1206" and "gemini-2.0-flash-thinking-exp-01-21". The first one doesn't even say what type of model it is, presumably it should have been "gemini-2.0-pro-exp-1206", but they didn't want to label it that for some reason, and now they're putting a hyphen in the date string where they weren't before.
Not to mention they have both "Flash" and "Flash-8B"... which I think will confuse people. IMO, it should be "Flash-${Parameters}B" for both of them if they're going to mention it for one.
But, I generally think Google's Gemini naming structure has been pretty decent.
