By Value (quality per dollar)
Raw cost isn't everything. A model that's 2x more expensive but produces 3x better output is actually cheaper per unit of quality.
The cheapest API is the one that gets the job done correctly on the first try.
For most production workloads, we recommend starting with GPT-4o mini or Gemini 2.5 Flash-Lite and upgrading only when needed.
Context Window Considerations
If you need to process long documents, Gemini 2.5 Pro (1M tokens) and Claude Sonnet 4.6 (200K tokens) offer significantly larger context windows, potentially eliminating the need for chunking and summarization.
