Sorted cheapest first on one-pass cost. Input-token count differs slightly per provider because each tokenizer has a different char-per-token ratio.
Approximation notes
Tokenization varies per model. Estimates use published char-per-token ratios from vendor docs (Anthropic ~3.5, OpenAI ~4.0, Gemini ~4.0). For precise counts, use tiktoken (OpenAI) or Anthropic’s count_tokens endpoint. Pricing last verified 2026-04-23.
