Outside AI models in workflows

Outside AI models in workflows is planned for HLB; the integration and setup details below describe the proposed functionality. It would add workflow actions that would send prompts and data to outside AI providers, then use the results in later steps, alongside the built-in GPT action.

OpenRouter

You would connect OpenRouter from Settings, Integrations with your API key. In a workflow, you would add the generate response action from the apps tab. You could set an optional system prompt for tone or role, a prompt with workflow variables such as the contact's first name, and the model. The response could go into an SMS or email, a custom field, conditions or another AI step. A plumbing company could use it to draft a follow-up after a missed appointment.

Mistral AI

Mistral actions would be labeled beta. You would connect a Mistral account, start the workflow with a standard trigger and then add an action:

• Create chat completion would handle replies, summaries, rewriting and classification
• Create embeddings would handle meaning-based matching and search
• Analyze image (vision) would handle receipts, screenshots, business cards and documents

Other providers

VAPI actions and triggers would let workflows start AI voice calls and chats, upload knowledge files and react to new calls. Manus would let workflows create, check, update and continue AI tasks, with triggers for created or stopped tasks. You would store the returned task ID in a custom field so later steps could retrieve the result.

The built-in GPT action would let you choose among models such as GPT-4o and GPT-4o mini, and would include preset action types for analyzing sentiment, summarizing and translating text, or writing a custom prompt.
