Which Gemini Models do we get access to (Gemini Developer Competition)

Are there any specific models we get access to or are we allowed to use any Gemmini Model? And are we allowed to use images as input to gemini?

Welcome to the forum!

You are allowed to use any Gemini Model that is available.

Since Gemini 1.5 is inherently multi-modal - image input is definitely allowed, and may even be encouraged!
