FAQ
Which AI models can you integrate?
I work with ChatGPT (GPT-3.5/GPT-4), Claude (Anthropic), and any OpenAI-compatible API. I also support LangChain, which lets you chain multiple models and tools together. Just let me know which model you prefer in the order requirements.
Do I need to provide my own API key?
Yes, you will need your own API key from OpenAI, Anthropic, or whichever provider you choose. This keeps your usage private and under your control. I will guide you on how to get one if needed, and I will never store or share your keys.
