What issue are you seeing?

I am getting a 404 Not Found: model 'gpt-5.5' not found error pointing to the local Ollama URL (http://127.0.0.1:11434/v1/responses) right after connecting to Ollama.

What steps can reproduce the bug?

1. Connect the app to Ollama.
2. Attempt to initialize or use the model.
3. The connection fails with the 404 error looking for 'gpt-5.5' on the local server.

What is the expected behavior?

It should correctly route requests or map to the locally available Ollama models instead of searching for a non-existent 'gpt-5.5' model on the local host.
