Use [Claude Sonnet 4.6](/models/claude-sonnet-4.6) when you need a practical balance. Use [GPT-5.4](/models/gpt-5.4) when OpenAI ecosystem fit matters. Use [MiniMax M2.7](/models/minimax-m2.7), [GLM-5](/models/glm-5), or [Qwen 3.5](/models/qwen-3.5) when open-source or local deployment matters.\n\n## Decision Rules\n\n| Situation | Pick | Why |\n|-----------|------|-----|\n| Highest coding quality | Claude Opus 4.6 | Top coding score in this dataset |\n| Daily coding assistant | Claude Sonnet 4.6 | Strong quality with lower cost than Opus |\n| Existing OpenAI stack | GPT-5.4 | Ecosystem and integration fit |\n| Local/open-source coding | Qwen 3.5, GLM-5, MiniMax M2.7 | Strong open-source coding scores |\n| Fast small edits | Claude Haiku 4.5 or Gemini 3 Flash | Lower cost and better latency |\n| Autonomous terminal work | Claude Code | Coding-agent workflow, not just model choice |\n\n## Use Opus When\n\n- The repo is large or unfamiliar.\n- The bug is subtle.\n- The task spans many files.\n- You need architectural judgment.\n- You want fewer failed attempts more than lower token cost.\n\n## Use a Cheaper Model When\n\n- The task is a small mechanical edit.\n- You already know the exact change.\n- You are generating boilerplate.\n- You can run tests cheaply.\n- You are doing bulk migrations where review catches errors.\n\n## Agent Workflow\n\n1. Fetch `/api/v1/recommend/coding.json`.\n2. Filter by `model_type`, cost, and deployment constraints.\n3. Fetch the top candidates via per-item JSON.\n4. Prefer the highest coding score only after checking context window and price.\n5. For codebase work, recommend an agent tool as well as a model.\n\n## Failure Mode\n\nThe common mistake is using the most expensive coding model for every edit. A good agent should reserve it for ambiguous, high-risk, or cross-file work.","content_length":2440,"generated_at":"2026-04-24"}
