In the previous article, you explored Ollama’s core features—installing the CLI, pulling models, and running large language models locally. Now, we’ll shift our focus to programmatic access: the Ollama REST API, which lets you interact with your local LLMs over HTTP instead of typing commands in a terminal.
  • Ensure you’ve installed the Ollama CLI and configured at least one local model (for example, ollama pull llama2).
  • Have your API base URL and authentication token ready if you’ve set up access controls.

What You’ll Learn

  • Ollama REST API Overview: Why and when to use the API over the CLI
  • Key Endpoints: Create, list, and chat operations you’ll rely on
  • Request & Response Flow: Emulate a conversational experience via HTTP
  • Hands-On Lab: Practice making real API calls
  • AI App Architecture: Fundamentals of integrating locally hosted LLMs
  • Python Demo: Build a simple application with the OpenAI Python client powered by Ollama
  • OpenAI Compatibility: How Ollama mirrors the OpenAI API for seamless production switch-overs
The image is a slide outlining topics to be covered about the Ollama REST API, including its introduction, available endpoints, and interaction methods.
This section will guide you through every step, from sending your first POST /v1/chat/completions request to handling streamed responses in your application.
The image is a slide titled "What We'll Cover," outlining topics related to building AI applications using Ollama, creating an app with the OpenAI Python client, and OpenAI compatibility.
Let’s dive in and start building!
