Claude Code is Anthropic's agentic coding tool — it lives in your terminal, reads your codebase, edits files, and runs commands. This episode covers how it can run on local models through Ollama, why that works, and what you give up when you take Anthropic out of the loop.

- Claude Code is an agent, not a chat window — it reads your codebase, edits files, runs shell commands, and loops until the task is done

- As of Ollama v0.14, Ollama natively speaks Anthropic's Messages API, which is what Claude Code sends — no translation proxy needed

- Ollama v0.15+ added `ollama launch claude`, which wires the integration up automatically with no config files or environment variables

- Anthropic does not officially support local models for Claude Code — this works because Ollama did the work, not because Anthropic blessed it

- Smaller local models handle routine tasks (completions, refactors, debugging) but degrade on long multi-step agentic work where tool-use precision matters

- Aider, Continue, and OpenCode were designed local-first from day one; Claude Code is cloud-first that can go local
