Thank you for reporting this issue! The error 404 model 'models/gemini-2.5-pro' not found with provider ollama indicates a model naming mismatch.

Likely cause: Ollama model IDs should not include the models/ prefix. That prefix is used by Google Gemini's API, but Ollama expects the exact model name as shown by ollama list (e.g., gemma2:2b, llama3.2, or gemini2.5-pro if you've pulled a model with that name).

Check:

• Open a terminal and run ollama list to see the exact names of your installed models.
• In Open CoDesign's settings, set the model ID to the name exactly as listed (e.g., gemini2.5-pro if that's the tag you pulled).

Relevant code: The app passes the modelId directly to the Ollama API (packages/providers/src/ollama.ts). The models/ prefix is not stripped for Ollama, so it sends the full string causing a 404.

Need more info:

• Could you run ollama list and share which model names appear?
• Did you manually type models/gemini-2.5-pro or was it suggested by the UI?

Thanks again for trying Open CoDesign! Let me know if the fix works.
