Ollama Python connects Python applications to models running through Ollama on your own machine or to Ollama's cloud service. It's for developers adding local LLM features to scripts, chat applications, or other Python projects. The library is open source under the MIT license and requires a running Ollama service for local use.
The client covers chat conversations and prompt-based text generation, with streaming responses so an application can display output as it arrives. It also generates embeddings for individual texts or batches. Synchronous and asynchronous clients let it fit into both ordinary scripts and applications that handle requests concurrently.
Model management is included. Python applications can download models, inspect their details, create variants with custom system prompts, and copy or delete them. The client can also list models currently running in Ollama. Its interface follows the Ollama REST API, with typed response objects for access to returned data.
Local requests go to your Ollama service. Cloud model requests send work to Ollama's servers, either through the local service or directly through ollama.com. Cloud access requires sign-in or an API key; supported models include gpt-oss, DeepSeek V3.1, and Qwen3-Coder.
For structured decisions, System One supports choice questions, true-or-false probabilities, and scores using compatible local models such as nimble. It returns a single JSON response and doesn't support streaming or cloud models.

Curator is a Python library for developers preparing LLM training datasets or extracting structured records from existing data. It supports local inference through Ollama and vLLM alongside cloud model APIs, so the same data pipeline can use models on your hardware or a hosted provider. It's open source under Apache 2.0.

Instructor is an open-source library for developers who need structured data from local LLMs or cloud models. It turns natural-language input into typed objects that applications can use, with validation and retries built into the extraction process. Its focus is data extraction.
LMQL is a programming language for developers who need model calls and ordinary Python logic in the same program. It lets you define rules for generated text, including types, length limits, allowed answers and stopping phrases. Those rules apply during generation, so you can constrain intermediate responses as well as the final output.
Ollama JavaScript connects Node.js and browser applications to models running through Ollama. It's for developers building chat interfaces, AI agents or other apps that need a local LLM backend. The library is open source under the MIT license, with TypeScript types and an API that follows Ollama's REST interface.
OllamaSharp is a C# library for developers building .NET applications around Ollama. It connects to Ollama on your own machine or a remote server and covers the full Ollama API, including model management alongside chat and embeddings. It's open source under the MIT license.
Pydantic AI is a Python SDK for developers building AI agents into their own applications. Its main draw is Pydantic validation across agent tools and results, so an agent can return structured data that application code can check and use. The SDK is MIT licensed.
