Best LLM provider for Proteus ProPilot AI Assistant

 Since Proteus Professional v9, Labcenter electronics has introduced ProPilot AI as an assistant for circuit creation, code generation and circuit troubleshooting and more. But the ProPilot AI relies on setting up LLM provider in order for the AI assistant to work. There are many well known LLM provider such Claude, ChatGPT, DeepSeek,Ollama(local) and custom as shown in the screenshot below.

Among all these LLM options, the best and free one is the Google Gemini v3 upwards. This has been working well for me for now.
