Question 1

Which tokenizer does Inception Labs use?

Accepted Answer

Inception Labs 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 Inception Labs token counts exact or estimated?

Accepted Answer

Estimated. Inception Labs 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 Inception Labs API cost calculated?

Accepted Answer

Cost equals tokens divided by one million, multiplied by the model's per-million-token rate. Each Inception Labs 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 Inception Labs API costs?

Accepted Answer

Inception Labs 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 Inception Labs models like Mercury 2 and Mercury 2.5 (Preview) before you commit.

Model	Tokens	Input Cost	Output Cost
Mercury 2	—	—	—
Mercury 2.5 (Preview)	—	—	—

Model	Input /1M	Output /1M	Context
Mercury 2	$0.250	$0.750	128K
Mercury 2.5 (Preview)	$0.200	$0.750	260K
