Most companies waste six figures on AI. They don't realize it until the bill hits.

The problem: You're using the wrong models for the wrong tasks.

1. Using GPT-4 When GPT-4o-mini Cuts Costs 95% → GPT-4: $30 per 1M tokens → GPT-4o-mini: $0.15 per 1M tokens → Same quality for 90% of tasks

This one switch saves $100K+ monthly.

2. Ignoring Context Caching on Repetitive Queries → Caching reduces costs 90% on repeated prompts → Most teams don't enable it → Every API call pays full price

Cache once, save thousands.

3. Poor Prompt Design Wasting 60% of API Calls → Vague prompts require multiple attempts → Missing instructions force regeneration → Unclear outputs need clarification rounds

One good prompt beats five bad ones.

4. Token Limits Crushing Accuracy on Long Documents → Truncating context loses critical information → Splitting documents creates inconsistent analysis → Wrong model choice for document length

Claude handles 200K tokens. GPT-4 handles 128K. Match your model to your data.

5. No Rate Limiting on Internal Tools → Employees running unlimited queries → Development hitting production APIs → Forgotten processes running 24/7

Set spending alerts before bills explode.

6. Paying for Features You Don't Use → Enterprise plans with unused seats → API tiers above actual usage → Add-ons never implemented

Audit subscriptions quarterly.

7. Running AI When Rules-Based Logic Works → Simple if-then tasks don't need AI → Classification that regex handles perfectly → Deterministic processes cost pennies

AI isn't always the answer.

8. No Fallback to Cheaper Models → Every query hits the most expensive model → Simple tasks overpay for capability → No routing logic by complexity

Route simple queries to cheap models.

One finance team found $847K in annual AI waste. Fixed it in two weeks with these changes.
