AI Model

A model provider as a node: configure Ollama / OpenAI-compatible / Anthropic (endpoint, key, model, fallback models) once, then wire this node into the ◈ Model port on ANY model-calling AI node (agent, chat, extract, eval, rerank, embeddings, vector-store, transcribe, speak, image) — the provider settings flow into every node it is attached to; modality nodes take the endpoint + key and keep their own model name. Re-wire to swap providers across the canvas.

Finding it in the library

Search the builder's node library for AI Model (it lives under AI). A single click opens the in-editor docs panel shown here — description, ports, and every property, without leaving the canvas. Double-click (or drag) to add it to the workflow.

Wired up in the builder

AI Model in a real, runnable flow — captured live from the Studio editor, exactly as it looks on your canvas. This is the same workflow used for the example input & output below.

How it’s configured

The node’s Configure panel as it opens in the builder when you select the step — every setting laid out with real values. Click any field to edit it.

Ports

Ports are the node’s contract with its neighbours. In the editor a port label renders bold when wired and italic when optional; ◈ ports accept attachment carriers rather than data wires.

How data flows through it

AI Model consumes the content of the incoming envelope — when it is fed directly by a trigger, the trigger’s wrapper is unwrapped at the node boundary so the node sees the actual data, not the metadata shell. Its output becomes the payload for the next node, while the envelope (trace ids, correlation, binary refs) rides along untouched. In the Runs view you always see the whole envelope for both sides of this node.

Expressions in the config

String-typed properties accept {{ }} expressions evaluated against the incoming item at run time — e.g. {{ $json.customer.email }}. On this node that’s baseUrl, apiKey, model. JSON- and code-typed fields never interpolate — they are passed through literally.

Build it with AI

Every node in this reference is reachable through Flowdrome’s AI Copilot and the MCP tools — say what you want, and the graph surgery happens server-side. Node types resolve fuzzily, so the catalog label (AI Model) works as well as the exact type id (ai.model).

In the Copilot panel (or any connected AI):

add a ai model node after the trigger

As a step in a create_chain_workflow call:

{"type":"AI Model","config":{}}

curl -s -X POST http://localhost:48170/mcp -H "content-type: application/json" -d '{ "jsonrpc": "2.0", "id": "1", "method": "tools/call", "params": { "name": "add_node", "arguments": { "workflowId": "<id>", "type": "AI Model" } } }'

Example input & output

Captured from a real test run of the workflow above — this is what you see in the run data panel after pressing Test workflow.

Input — what the node received

Output — what the node produced

Property reference

Every setting, with its type and default — the same fields shown configured in the panel above.
