Currently, HubSpot’s “Connect your LLM to custom workflow actions” feature supports OpenAI, Anthropic, Gemini, Cohere, and xAI. I’d like to propose adding Microsoft Copilot as an additional supported LLM provider.
Many companies are deeply invested in the Microsoft ecosystem (Microsoft 365, Azure, Copilot) and cannot use external LLM providers due to compliance, data residency, or security requirements.
