Google announced Gemini 3 Flash (regular Gemini 3 and Gemini 3 Deep Think launched just last month).

• Gemini 3 Flash is also rolling out globally in Google Search, as the default model in AI Mode.
• You can also select "Thinking with 3 Pro" in the AI Mode model drop-down menu if you want to use Gemini 3 Pro.
• Nano Banana Pro (aka Gemini 3 Pro Image) is also available in AI Mode: choose the "Thinking with 3 Pro" model and choose "Create Images Pro"

Checked AI Mode and I'm able to access these new models. Got a fast standard AI Mode answer. When I asked it to create an infographic using Create Images Pro it took about 45 seconds and did a good job.
