The 5 levers that cut your AI bill
Prompt caching (90% off cached input). Batch API (50% off for async). Right-sized model (Haiku not Sonnet, Sonnet not Opus for routine work). Off-peak DeepSeek (50% off again). Self-host for sustained workloads. Most teams underutilize all five and end up paying 3-5x what they need to. Run your numbers through the calculators above before signing any annual contract.
Picking the right model in 2026
Default to Claude Sonnet 4.6 or GPT-5 for general use; reach for Opus / o-pro only when you've measured a real quality gap. Use DeepSeek V3.2 for high-volume agent loops where total cost dominates. Use Gemini 2.5/3 Pro for native multimodal or 2M context. Self-host Qwen 3.5 or Llama 3.3 if privacy or cost matters more than latency. The frontier-model-tracker above keeps the lineup current.
