Notes & extras
- Reasoning tokens: billed as output
- Tiered pricing. A request whose prompt reaches 200k tokens is billed at the higher rate for every token in the request, not just the tokens above the threshold. Token counts are approximated with o200k_base; xAI's tokenizer is not runnable in the browser.
