MTU Consumption and Weights

Monitor MT usage in the MT usage tab of Phrase Language AI.

Phrase calculates MTU usage based on each character sent to a machine translation service using the following calculation:

A * (B + C) = Machine Translation Units

Where:

A is the total number of characters that the customer sends for machine translation.
B is the weight assigned by Phrase to the applicable machine translation service.
C is the weight assigned by Phrase to reflect the additional features made available in Phrase Language AI (e.g. autoselect, QPS, MT glossaries, etc.).

This weight is always applied to any machine translation performed via Phrase Language AI, even if the additional features are not used.

Features that consume MTUs are:

Examples

Manually managed engine with autoselect and QPS:

Manually managed engine with autoselect and without QPS:

Fully managed engine (e.g. Phrase NextMT) with autoselect and QPS:

Fully managed engine (e.g. Phrase NextMT) with autoselect and without QPS:

Type	Weight
With or without additional features	0.5

Use the Apply MT only when there's no TM match at or above the threshold in pre-translation to ensure that MT is only used when there is no TM match at or above the set threshold.
When translating a job in the editor, use the Suggest MT only for segments with a TM match below {set value}.

This ensures:
- MT suggestions will only be offered if there is no TM match at or above the set threshold.
- Autocomplete will not use MT units to make suggestions.
- MT is not suggested in following workflow steps for segments confirmed in the previous step, as there will be an adequate TM match available.
When creating a default analysis, disable the Include machine translation matches (QPS) option.
