Anthropic Pricing & Token Calculator
All 13 Anthropic models on one page: context windows, tokenizer behaviour and list price per 1M input and output tokens. Each row links to a dedicated calculator already preselected to that model.
Anthropic does not publish a public tokenizer, so TokenCalc estimates Claude counts from character ratios calibrated against Anthropic's published benchmarks.

Cheapest Anthropic models per 1M input tokens
ERNIE X1 at $0.006/1M, Doubao 1.6 Flash at $0.01/1M, text-embedding-3-small at $0.02/1M, Doubao 1.6 Lite at $0.02/1M, SenseNova 5.1 (商汤) at $0.04/1M. Output rates run several times higher than input rates on most vendors, so a token-heavy workflow with long generations is priced by the output column.
Largest Anthropic context windows
Gemini 3.1 Pro (2M), Gemini 2.5 Pro (2M), GPT-5.5 (1M). Context headroom is usually the binding constraint before price is — check it first.
