module  pixeltable.functions.ollama

Pixeltable UDFs for Ollama local models. Provides integration with Ollama for running large language models locally, including chat completions and embeddings.

​
udf  chat()

Signature
chat(
    messages: pxt.Json,
    *,
    model: pxt.String,
    tools: pxt.Json | None = None,
    format: pxt.String | None = None,
    options: pxt.Json | None = None
) -> pxt.Json
Generate the next message in a chat with a provided model. Parameters:
  • messages (pxt.Json): The messages of the chat.
  • model (pxt.String): The model name.
  • tools (pxt.Json | None): Tools for the model to use.
  • format (pxt.String | None): The format of the response; must be one of 'json' or None.
  • options (pxt.Json | None): Additional options to pass to the chat call, such as max_tokens, temperature, top_p, and top_k. For details, see the Valid Parameters and Values section of the Ollama documentation.

​
udf  embed()

Signature
embed(
    input: pxt.String,
    *,
    model: pxt.String,
    truncate: pxt.Bool = True,
    options: pxt.Json | None = None
) -> pxt.Array[(None,), Float]
Generate embeddings from a model. Parameters:
  • input (pxt.String): The input text to generate embeddings for.
  • model (pxt.String): The model name.
  • truncate (pxt.Bool): Truncates the end of each input to fit within context length. Returns error if false and context length is exceeded.
  • options (pxt.Json | None): Additional options to pass to the embed call. For details, see the Valid Parameters and Values section of the Ollama documentation.

udf  generate()

Signature
generate(
    prompt: pxt.String,
    *,
    model: pxt.String,
    suffix: pxt.String = '',
    system: pxt.String = '',
    template: pxt.String = '',
    context: pxt.Json | None = None,
    raw: pxt.Bool = False,
    format: pxt.String | None = None,
    options: pxt.Json | None = None
) -> pxt.Json
Generate a response for a given prompt with a provided model. Parameters:
  • prompt (pxt.String): The prompt to generate a response for.
  • model (pxt.String): The model name.
  • suffix (pxt.String): The text after the model response.
  • format (pxt.String | None): The format of the response; must be one of 'json' or None.
  • system (pxt.String): System message.
  • template (pxt.String): Prompt template to use.
  • context (pxt.Json | None): The context parameter returned from a previous call to generate().
  • raw (pxt.Bool): If True, no formatting will be applied to the prompt.
  • options (pxt.Json | None): Additional options for the Ollama chat call, such as max_tokens, temperature, top_p, and top_k. For details, see the Valid Parameters and Values section of the Ollama documentation.
