At Claude Fable 5's rates ($10 per 1M input tokens, $50 per 1M output), a call with 1,000 input and 500 output tokens costs $0.035. At 10,000 requests a month, that workload runs $350.00. A heavier call — a 100,000-token prompt returning 2,000 tokens — costs $1.10.

Claude Fable 5 is the priciest Anthropic Claude model at this workload, 10.0× the per-call cost of Claude Haiku 4.5.

Cache-read input is billed at $1 per 1M tokens — 90% below the standard input rate, so a long system prompt reused across calls mostly bills at the discounted rate.

Token counter

0 tokens

Token counts are exact for OpenAI models (tiktoken o200k_base, run in your browser). For other providers the count is an estimate — notably Claude Opus 4.7+/Sonnet 5 and similar newer models use a tokenizer that produces roughly 30% more tokens for the same text.
