I first ran a hybrid Claude + GPT coding agent in VS Code back in late 2024 on raw OpenAI and Anthropic keys, and the monthly invoice made me wince — about $612 for what was essentially one refactor sprint. When I moved the same workload to HolySheep's relay in Q1 2026, the identical month dropped to $94 on my dashboard. That's the entire promise of this guide: walk you through wiring Cline to use Claude Opus 4.7 for planning and GPT-5.5 for execution, both routed through HolySheep's OpenAI-compatible endpoint, so you keep the model quality and shed roughly 85% of the sticker price.

Before we touch VS Code, the table below tells you whether HolySheep is even worth your time compared to going direct or using another community relay.
