Dynamically switch between LLMs Template
Configured with Chain LLM, Chat Trigger, OpenAI Chat Model, Sentiment Analysis. Review the connections and setup before adapting this template.
Node categories in this workflow
- Trigger
- Code
- Transform
- Routing
- AI & models
Icons describe general node roles, inferred from node types. Inspect the parameters for the configured action.
Drag to pan; use + and − to zoom. Reconstructed from the exported node positions; nothing runs here. Dashed lines represent non-main connections. Full node names and notes appear below.
How it works
The exported workflow contains the following configured nodes. Their connections are shown above; inspect the JSON for the complete logic, expressions, and external actions.
| Node | Category | Type | Operation |
|---|---|---|---|
| When chat message received | Trigger | Chat Trigger | See node parameters |
| Switch Model | Code | Code | See node parameters |
| Set LLM index | Transform | Edit Fields | See node parameters |
| Increase LLM index | Transform | Edit Fields | See node parameters |
| No Operation, do nothing | Routing | No Op | See node parameters |
| Check for expected error | Routing | If | See node parameters |
| Loop finished without results | Transform | Edit Fields | See node parameters |
| Unexpected error | Transform | Edit Fields | See node parameters |
| Return result | Transform | Edit Fields | See node parameters |
| OpenAI 4o-mini | AI & models | OpenAI Chat Model | See node parameters |
| OpenAI 4o | AI & models | OpenAI Chat Model | See node parameters |
| OpenAI o1 | AI & models | OpenAI Chat Model | See node parameters |
| OpenAI Chat Model | AI & models | OpenAI Chat Model | See node parameters |
| Validate response | AI & models | Sentiment Analysis | See node parameters |
| Generate response | AI & models | Chain LLM | See node parameters |
Setup
- Download the JSON and import it into an isolated n8n instance. Leave the workflow inactive.
- Connect your own credentials through n8n’s credential store. Replace
REPLACE_WITH_*values with your resource identifiers. - Inspect API destinations, Code nodes, database queries, file paths, and outbound actions.
- Run with synthetic data and harmless destinations. Enable triggers only after checking the actual outputs.
Requirements
An n8n instance with the listed node types and compatible versions. Service-connected workflows may require accounts, credentials, or paid APIs.
Credential types declared in the source
openAiApi
Workflow notes
Customer complaint - example
Customer complaint - example
I really love waiting two weeks just to get a keyboard that doesn’t even work. Great job. Any chance I could actually use the thing I paid for sometime this month?
Sticky Note1
Defines the LLM node by index which should be used.
Sticky Note2
Dynamically connects the LLM by the index provided in the previous node.
Sticky Note3
Check if LangChain Code Node ran into error. Currently only supports error output from main Node
Sticky Note4
Generates a polite answer based on the customers complaint.
Sticky Note5
Analyses the generated answer by certain criteria
Sticky Note6
Increases the index to choose the next available LLM on the next run

Purpose and structure
This folder contains the Dynamically switch between LLMs Template workflow. Its executable nodes use chainLlm, chatTrigger, code, if, lmChatOpenAi, noOp, sentimentAnalysis, set. The table and connection map below are derived from the JSON, not an inferred guarantee of behavior.
Setup
Import inactive. Configure your own credentials and replace REPLACE_WITH_* values. Review external destinations and Code nodes before running.
Entry points
When chat message received
Verification
Sanitized source candidate; not runtime-tested. This overview is generated from node metadata. Read the folder README for the connection map, credential types, and license.
