GitHub Copilot is also powered by OpenAI GPT, Anthropic Claude, or Google Gemini, but has not (yet) published an API for the Copilot product. As soon as they publish an API, we will look into this.
Over the past few days, I've noticed that DBeaver now supports integration with GitHub Copilot, which suggests the relevant API is already available. I would urge you to implement this integration as soon as possible, as most companies are already utilising this feature.
