How DeepSeek tokenization works
DeepSeek publishes its tokenizer with its open-weight releases, and this page runs the DeepSeek V3 tokenizer in your browser — exact for V3 and R1 family models, and the best available basis for newer releases.
DeepSeek consistently prices among the cheapest hosted APIs per million tokens, which is why it appears in most cost-comparison shortlists.
Catalog models support context windows up to 1 million tokens.
