Describe the bug

I use qwen3.6-plus model. Copilot CLI take 40% of my tockens in 3 hours, but claude use 3% only,when do same things. But when I use deepseek in copilot CLI ,it save tockens very much such as I use qwen3.6-plus model in claude code. So, what't the matter with copilot CLI and qwen3.6-plus. I will not use copilot CLI, if it takes so much tokens.
