I use Claude Code as an orchestrator and have the agents use different models:

  product-designer   ollama-cloud / qwen3.5:cloud
  pm                 ollama-cloud / glm-5:cloud
  test-writer        claude-code  / Sonnet 4.6
  backend-builder    claude-code  / Opus 4.6
  frontend-builder   claude-code  / Opus 4.6
  code-reviewer      codex-cli    / gpt-5.1-codex-mini
  git-committer      ollama-cloud / minimax-m2.5:cloud

I use ollama pro $20/month and OpenAI $20/month. I have an Anthropic max plan at $100/month.
