This article shows how to set up Google’s open-source Gemma 4 coding model in Anthropic’s Claude Code via Ollama Cloud or locally. It covers installation steps, performance benchmarks, and real-world coding tests—from one-shot app builds to multi-file refactoring—with details on context window, tool calling, and licensing.

The transition from vibe coding to compound engineering marks a significant shift in software development, enabling productivity gains of 300-700% through optimized feedback loops and automated testing. Engineers are redefined as system orchestrators, focusing on crafting precise specifications and managing the rapid iteration of AI-generated code rather than writing code themselves. This new paradigm emphasizes the importance of automated guardrails and end-to-end testing in maintaining system coherence and efficiency.
