Langchain.Embeddings.Ollama

Description

Ollama implementation of LangChain's embedding interface. Supports document and query embedding generation through Ollama's API.

Example usage:

-- Create Ollama embeddings configuration
ollamaEmb = OllamaEmbeddings
  { model = "llama3"
  , defaultTruncate = Just True
  , defaultKeepAlive = Just "5m"
  }

-- Embed query text
queryVec <- embedQuery ollamaEmb "What is Haskell?"
-- Right [0.12, 0.34, ...]

-- Embed document collection
doc <- Document "Haskell is a functional programming language" mempty
docsVec <- embedDocuments ollamaEmb [doc]
-- Right [[0.56, 0.78, ...]]

Synopsis

data OllamaEmbeddings = OllamaEmbeddings {
- model :: Text
- defaultTruncate :: Maybe Bool
- defaultKeepAlive :: Maybe Text
}

Documentation

data OllamaEmbeddings Source #

Ollama-specific embedding configuration Contains parameters for controlling:

Model selection
Input truncation behavior
Model caching via keep-alive

Example configuration:

>>> OllamaEmbeddings "nomic-embed" (Just False) (Just "1h")
OllamaEmbeddings {model = "nomic-embed", ...}

Constructors

OllamaEmbeddings
Fields model :: Text The name of the Ollama model to use for embeddings defaultTruncate :: Maybe Bool Optional flag to truncate input if supported by the API defaultKeepAlive :: Maybe Text Keep model loaded for specified duration (e.g., "5m")

Embeddings OllamaEmbeddings Source #	Ollama implementation of the `Embeddings` interface [[6]]. Uses Ollama's embedding API for vector generation. Handles: - Multiple document embedding via batch processing - Query embedding for similarity searches - Error propagation from API responses Example instance usage: `-- Embed multiple documents docs <- load (FileLoader "data.txt") case docs of Right documents -> do vecs <- embedDocuments ollamaEmb documents -- Use vectors for semantic search Left err -> print err`
