💰 Critical Billing Rules
📉 Efficiency Strategies
1
Prune Your Pins
Unpin files (
@) as soon as you are done with them. Every pinned file adds to the input cost of every message in that thread.2
The 200k Token Reset
Once a thread exceeds 200,000 tokens, providers often implement a surcharge. When you hit this threshold, Start a New Thread.
3
Smart Routing
Use Gemini 3 Pro for deep codebase research, but switch to Claude 4.5 Haiku or GPT-5.1 for writing individual methods to keep your costs low.
