Is this the gemini-exp model on LMArena?
Yes, LMArena shows Gemini-2.0-Flash-Exp ranking 3rd right now, after Gemini-Exp-1206 and ChatGPT-4o-latest_(2024-11-20), and ahead of o1-preview and o1-mini: https://lmarena.ai/?leaderboard
EDIT: probably not deep research.. is it Google testing their equivalent of o1? who knows..
