Ollama Model node documentation
Learn how to use the Ollama Model node in n8n. Follow technical documentation to integrate Ollama Model node into your workflows.
Ollama Model node
The Ollama Model node allows you use local Llama 2 models.
On this page, you'll find the node parameters for the Ollama Model node, and links to more resources.
This node lacks tools support, so it won't work with the AI Agent node. Instead, connect it with the Basic LLM Chain node.
Credentials
You can find authentication information for this node here.
Parameter resolution in sub-nodes
Sub-nodes behave differently to other nodes when processing multiple items using an expression.
Most nodes, including root nodes, take any number of items as input, process these items, and output the results. You can use expressions to refer to input items, and the node resolves the expression for each item in turn. For example, given an input of five name values, the expression {{ $json.name }} resolves to each name in turn.
In sub-nodes, the expression always resolves to the first item. For example, given an input of five name values, the expression {{ $json.name }} always resolves to the first name.
Node parameters
- Model: Select the model that generates the completion. Choose from:
- Llama2
- Llama2 13B
- Llama2 70B
- Llama2 Uncensored
Refer to the Ollama Models Library documentation for more information about available models.
Node options
- Sampling Temperature: Use this option to control the randomness of the sampling process. A higher temperature creates more diverse sampling, but increases the risk of hallucinations.
- Top K: Enter the number of token choices the model uses to generate the next token.
- Top P: Use this option to set the probability the completion should use. Use a lower value to ignore less probable options.
