Claude vs GPT vs Gemini API pricing

A few commonly used models from each family, with their per-token prices on XHuoAPI, monthly costs at fixed volumes, and how to choose by price. All three use the same API key and endpoint; switching is a change to the model field. Claude models also accept the Anthropic format.

Per-token prices

Prices below are for the Standard tier (the default for new accounts), in USD per million tokens. "Lowest tier" is the cheapest tier the model is available in; Saver and Spot cost less and are less reliable. The pricing page explains the difference.
