Stop Overpaying for AI: A Practical Guide to LLM Cost Optimization

Most teams default to the most capable model for everything. That's like hiring a senior engineer to write meeting notes.

The Actual Cost Difference

Claude Haiku: $0.80/MTok input, $4.00/MTok output. Claude Sonnet: $3.00/MTok input, $15.00/MTok output. At 1000 calls/day with 500 input / 300 output tokens: Haiku = $1.58/day. Sonnet = $5.99/day. Monthly: Haiku $47 vs Sonnet $180.

Use Haiku For

Summarization, classification, extraction, template filling, code review checklists, formatting, structured data parsing. Anything where the task is well-defined and the output is predictable.

Use Sonnet For

Complex reasoning, ambiguous problems, nuanced writing, multi-step analysis, tasks where quality is visibly important to end users.
