5 LLM Cost Mistakes I Made (And the One Fix That Saved 40%)

Sharing my actual mistakes so you can skip them.

Mistake 1: Using Sonnet for File Reads

Paying $0.015/1K tokens to read a config file. DeepSeek does this for $0.0014. Identical output.

Mistake 2: Long Sessions

By message 30, every prompt carries 80K+ tokens of history. I was paying for context I did not need. Now I start fresh sessions aggressively.

Mistake 3: Not Tracking Per-Task Costs

Had no idea where my money went until I logged every API call for a month. 60% was routine tasks at premium prices.

Mistake 4: Manual Model Switching

Tried switching models manually for a week. The cognitive load of deciding per-prompt was worse than the cost savings. Automated it.

Mistake 5: Single Provider

All eggs in one basket. When Claude went down, everything stopped.

The One Fix

Auto-routing by task type. Cheap model for the 60%, premium for the 40%. TeamoRouter handles this. Free tier available.

Result: $240/mo → $140/mo.
