- 44. The 7 prompts
- 55. When something does not work
1. How to run both, fairly
- One empty folder per run. Each model starts from nothing, so neither sees the other's work.
- Pick the model.
/model claude-fable-5-1for the old one./model fablefor Fable 5.2. - Set the same effort on both. Type
/effort high. That is what both sides of this test used. - Paste the prompt once. No follow-ups. One shot is the whole test. Then open both index.html files in Chrome side by side.
2. The full bill
Same prompt, one shot each, no fixes. These are the costs Claude Code reports at API prices. On a Pro or Max plan you pay your plan instead.
