Token counts are approximations based on character + word heuristics with per-tokenizer ratios. For exact counts use each provider's tokenizer (cl100k_base / Anthropic's tokenizer / SentencePiece). Prices are list rates as of early 2026 and may have changed โ€” verify against the provider's pricing page.
