[Bug]: Issues with Google Gemini API via Custom Provider

Description

I am trying to use Google Gemini API (via Google AI Studio) in Open CoDesign by using the Custom Provider option. I've configured the Base URL as https://generativelanguage.googleapis.com/v1beta/openai/ and provided my API key, but I'm encountering stability issues/errors when the agent tries to generate code.

Steps to reproduce

Set Provider to Custom.

URL: https://generativelanguage.googleapis.com/v1beta/openai/

Model ID: gemini-1.5-pro (or gemini-1.5-flash)

Start a new design task.

Expected behavior

The agent should communicate with Gemini and start generating the project files as it does with OpenAI or Anthropic.

Actual behavior

Is anyone else successfully using Gemini via the Custom Provider?
