What the Numbers Reveal
After comparing pricing across all 88 models, clear patterns emerge:
- Budget models are 10-50x cheaper than premium models for the same output quality on most tasks.
- Open-source models (Llama, GPT-oss, DeepSeek) offer the absolute lowest costs when self-hosted or used via providers like Together.ai.
- Google's Gemini Flash Lite ($0.075) is the single cheapest API available — ideal for high-volume, low-complexity tasks.
- GPT-5 mini ($0.25/$2) is the best value-for-money model — near-premium quality at budget pricing.
- Context window matters: Gemini models offer 1M context at budget prices, while GPT-5 offers 272K. For long documents, Gemini wins on both price and context.
The Smart Strategy: Tiered Model Routing
The biggest savings come not from picking one cheap model, but from routing requests by complexity:
