Default model does not work

[Sparshsing]

Description of the bug:

• The default model gemini-2.5-computer-use-preview-10-2025 does not work for the free gemini api key.
  (not sure if it happens for paid api plan too).
• However, the model gemini-3-flash-preview works fine.

Actual vs expected behavior:

Actual:

When the computer use script is run with the defaults:
python main.py --query="Go to Google and type 'Hello World' into the search bar"
It gives errors even on the first try

google.genai.errors.ClientError: 429 RESOURCE_EXHAUSTED. {'error': {'code': 429, 'message': 'You exceeded your current quota, please check your plan and billing details. For more information on this error, head to: https://ai.google.dev/gemini-api/docs/rate-limits. ...

Expected

The computer use script should work with the default model, even for the free gemini api key.
Probably the default model should be updated to gemini-3-flash-preview.
This model gives the correct output something like this:
