A developer explored running the Claude Code AI agent locally using a Qwen3.5 4B model on an RTX 4070, aiming to reduce costs and enhance privacy. The experiment revealed that while 97% of individual agent steps could be handled locally, 96% of the overall requests required the frontier model for complex planning. The developer found that a simple rule-based routing system, prioritizing local execution for specific tools like WebFetch and routing complex tasks to the frontier model, was more effective than a probabilistic approach.
