List Running Models API
Model Types

Description

This module provides functions to retrieve a list of models currently running on the Ollama server. It includes both an IO-based function (ps) and a monadic version (psM) for use in MonadIO contexts. The operation is performed via a GET request to the "api/ps" endpoint, returning a RunningModels type containing a list of RunningModel records with details about each running model.

Example:

>>> ps Nothing
Right (RunningModels [RunningModel ...])

Synopsis

ps :: Maybe OllamaConfig -> IO (Either OllamaError RunningModels)
psM :: MonadIO m => Maybe OllamaConfig -> m (Either OllamaError RunningModels)
newtype RunningModels = RunningModels [RunningModel]
data RunningModel = RunningModel {
- name_ :: !Text
- modelName :: !Text
- size_ :: !Int64
- modelDigest :: !Text
- modelDetails :: !ModelDetails
- expiresAt :: !UTCTime
- sizeVRam :: !Int64
}

List Running Models API

ps Source #

Arguments

:: Maybe OllamaConfig	Optional `OllamaConfig` (defaults to `defaultOllamaConfig` if `Nothing`)
-> IO (Either OllamaError RunningModels)

Retrieves a list of currently running models from the Ollama server.

Sends a GET request to the "api/ps" endpoint to fetch the list of running models. Returns Right with a RunningModels containing the list of RunningModel on success, or Left with an OllamaError on failure. Example:

>>> ps Nothing
Right (RunningModels [RunningModel {name_ = "gemma3:instance1", modelName = "gemma3", ...}])

psM :: MonadIO m => Maybe OllamaConfig -> m (Either OllamaError RunningModels) Source #

MonadIO version of ps for use in monadic contexts.

Lifts the ps function into a MonadIO context, allowing it to be used in monadic computations.

Model Types
