Question 1

Which tokenizer does Tencent use?

Accepted Answer

Tencent uses its own tokenizer, which is not publicly available to run in a browser. This counter estimates counts with OpenAI's cl100k_base encoding, which is typically within roughly 10 to 20 percent of the real count for English text.

Question 2

Are these Tencent token counts exact or estimated?

Accepted Answer

Estimated. Tencent has not released its tokenizer for browser use, so this tool approximates counts with OpenAI's cl100k_base encoding. Estimates are usually close for English text but can drift for code, JSON, and non-English languages. Estimated counts are marked with a tilde (~).

Question 3

How is Tencent API cost calculated?

Accepted Answer

Cost equals tokens divided by one million, multiplied by the model's per-million-token rate. Each Tencent model has separate input and output rates, and this page shows both: what your text would cost as a prompt (input) and what the same number of tokens would cost as a response (output).

Question 4

Why do token counts matter for Tencent API costs?

Accepted Answer

Tencent bills API usage per token, not per word or character. A token is roughly 4 characters or about three quarters of a word in English. Knowing the token count of your prompts lets you predict spend, stay inside context windows, and compare Tencent models like Hy4 preview, Hy3 and Hunyuan HY3 Preview before you commit.

Model	Tokens	Input Cost	Output Cost
Hy4 preview	—	—	—
Hy3	—	—	—
Hunyuan HY3 Preview	—	—	—

Model	Input /1M	Output /1M	Context
Hy4 preview	$0.834	$2.50	1.0M
Hy3	$0.132	$0.528	262K
Hunyuan HY3 Preview	$0.178	$0.595	262K
