Ollama

new Ollama(config);

• config <Object> The configuration object for Ollama.
  • address <string> The Ollama API address. Default: "http://localhost:11434".

Create a new API handler for ollama.

generate

ollama.generate(model, prompt, [options]);

• model <string> The name of the model to use for the prompt.
• prompt <string> The prompt to give the model.
• options <GenerateOptions> Optional options to pass to the model.
  • parameters <ModelParameters> Model Parameters.
  • context <number[]> Context returned from previous calls.
  • template <string> Override the default template.
  • system <string> Override the default system string.
• Returns: <AsyncGenerator<string, GenerateResult>> A generator that outputs the tokens as strings.

Generate a response for a given prompt with a provided model. The final response object will include statistics and additional data from the request.

create

ollama.create(name, path);

• name <string> The name of the model.
• path <string> The path to the Modelfile.
• Returns: AsyncGenerator<CreateStatus> A generator that outputs the status of creation.

Create a model from a Modelfile.

tags

ollama.tags();

• Returns: Promise<Tag[]> A list of tags.

List models that are available locally.

copy

ollama.copy(source, destination);

• source <string> The name of the model to copy.

Download a model from a the model registry. Cancelled pulls are resumed from where they left off, and multiple calls to will share the same download progress.

embeddings

ollama.embeddings(model, prompt, [parameters]);

• model <string> The name of the model to generate embeddings for.
• prompt <string> The prompt to generate embeddings with.
• parameters <ModelParameters> Model Parameters.
• Returns: Promise<number[]> The embeddings.

Generate embeddings from a model.
