llm-ollama 0.4.3

LLM plugin providing access to local Ollama models

llm-ollama

LLM plugin providing access to models running on local Ollama server.

Installation

Install this plugin in the same environment as LLM.

llm install llm-ollama

Usage

First, ensure that your Ollama server is running and that you have pulled some models. You can use ollama list to check what is locally available.

The plugin will query the Ollama server for the list of models. You can use llm ollama list-models to see the list; it should be the same as output by ollama list. All these models will be automatically registered with LLM and made available for prompting and chatting.

Assuming you have llama2:latest available, you can run a prompt using:

llm -m llama2:latest 'How much is 2+2?'

The plugin automatically creates a short alias for models that have :latest in the name, so the previous command is equivalent to running:

llm -m llama2 'How much is 2+2?'

To start an interactive chat session:

llm chat -m llama2

Chatting with llama2:latest
Type 'exit' or 'quit' to exit
Type '!multi' to enter multiple lines, then '!end' to finish

Model aliases

The same Ollama model may be referred by several names with different tags. For example, in the following list, there is a single unique model with three different names:

ollama list
NAME                    ID              SIZE    MODIFIED
stable-code:3b          aa5ab8afb862    1.6 GB  9 hours ago
stable-code:code        aa5ab8afb862    1.6 GB  9 seconds ago
stable-code:latest      aa5ab8afb862    1.6 GB  14 seconds ago

In such cases, the plugin will register a single model and create additional aliases. Continuing the previous example, this is what LLM will have:

llm models
...

Ollama: stable-code:3b (aliases: stable-code:code, stable-code:latest, stable-code)

Model options

All models accept Ollama modelfile parameters as options. Use the -o name value syntax to specify them, for example:

• -o temperature 0.8: set the temperature of the model
• -o num_ctx 256000: set the size of the context window used to generate the next token

See the referenced page for the complete list with descriptions and default values.
