This page compares what DeepSeek and xAI charge through their APIs. Every price below carries the day we read it and links to the page it came from. We do not rank quality: we tell you what each model costs, and since when.

At the top of each range

The index is produced by Artificial Analysis and relayed through OpenRouter's catalogue. It is not our measurement; we record it as a level 4 source and show it next to the price we read. A model without a score here has not been scored yet, which is not the same as scoring low.
