Needs changesNeeds changes. This template uses 1 thing(s) that n8n 3.0 removes: AI Agent v1 (old agent modes). 1 breaking item(s) found. Static check, last run 2026-10-19.
What this workflow does
This AI workflow has 14 nodes and runs when a chat message arrives. Along the way it connects DeepSeek Chat Model, Embeddings OpenAI, OpenAI Chat Model and Google Sheets and 1 more.
How it runs
Trigger: When a chat message arrives.
- Merge: merges the data from its input branches
- Intent Classifier (AI Agent): runs an AI agent, with model: DeepSeek LLM; memory: Classifier Memory
- Aggregate: combines items into one
- Fetch System Prompt (Google Sheets): uses Google Sheets
- AI Teacher Agent (AI Agent): runs an AI agent, with model: GPT-4o-mini LLM; 1 tool (Book Knowledge Base); memory: Teacher Session Memory
- Log Q&A to Sheets (Google Sheets): append
- Format Response Output (Edit Fields (Set)): sets or maps fields
Services it uses
Before you upgrade to n8n 3.0
1 thing in this workflow is removed in n8n 3.0. Fix it before you upgrade:
- AI Agent v1 (old agent modes) in Intent Classifier (v1.9), AI Teacher Agent (v1.9): replace with Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent.
Rather not rewrite it? Many of these flows can be rebuilt in Make (free plan).
| Removed in 3.0 | Replace with |
|---|---|
| AI Agent v1 (old agent modes) Intent Classifier (v1.9), AI Teacher Agent (v1.9) | Latest AI Agent node (Tools Agent). For SQL Agent, use a Postgres or MySQL tool with a recent AI Agent. |
