How to Run Claude Code for Free with Local and Cloud Models from Ollama

Ollama now offers compatibility with Anthropic's Messages API, enabling users to run the Claude Code command-line tool for free. By using Ollama, developers can download and run powerful open-source large language models locally on their own machines, bypassing the costs associated with Anthropic's cloud services. The process involves installing Ollama, pulling desired models like gpt-oss:20b, and then installing Claude Code. This setup allows for generating code with local models, providing a cost-effective solution for development and learning.
