Got the same problem. If you run

!pip install -U git+https://github.com/google-gemini/generative-ai-python@imagen

import google.generativeai as genai
import pprint

for model in genai.list_models(page_size=100): # page_size can be any number
    pprint.pprint(model.name) 

Available Models Instead of seeing the Imagen 3 model ("imagen-3.0-generate-001") or any image generation models, here's what it returns, or at least what I get:

Problem: According to Google's blog post, there is a waitlist for accessing Imagen 3. To join, you need to fill out the "Labs.google Trusted Tester Waitlist," which requires providing credentials—a process that feels like getting military clearance.

Has anyone successfully accessed Imagen 3 through the API? Any tips or alternative steps to get this model up and running?
