OPUS-CAT can be used in different Wordfast CAT tools by using the Custom MT functionality offered by these products. NOTE: Make sure you use latest version of OPUS-CAT MT Engine with Wordfast. Earlier versions of OPUS-CAT MT Engine required extra configuration to enable it to be used with Wordfast.
Installing the OPUS-CAT MT Engine
- Download the OPUS-CAT MT Engine and install it to your computer by extracting it in a folder on your computer. IMPORTANT: OPUS-CAT MT Engine generates the machine translation, and all OPUS-CAT plugins require that the OPUS-CAT MT Engine is installed on the same computer and running when the plugins are used.
- Start the OPUS-CAT MT Engine application by clicking OpusCatMTEngine.exe in the extraction folder (note that the file extension .exe may be hidden in Windows Explorer, in that case the file is shown as OpusCatMTEngine).
- Install models from the OPUS model repository for the language pairs that you require.
- After the model has been downloaded and installed, test that it works.
Using OPUS-CAT in Wordfast Pro
- Make sure that OPUS-CAT MT Engine is running.
- Click the Preferences icon in the Wordfast Pro UI:

- Select Machine translation from the left and check the Enable Custom MT checkbox:

- Enter the URL for accessing the HTTP API of OPUS-CAT MT Engine into the URL field, and enter translation into the JSON Key field:

The value of the URL should have the following format:
http://localhost:8500/MTRestService/TranslatePost?tokenCode=0&input={ss}&srcLangCode=en&trgLangCode=fi&modelTag=
NOTE: The srcLangCode and trgLangCode values in the URL should be replaced with the two-letter codes of the source and target language of the project. So if the source language of the project is e.g. French and the target language English, the URL should be the following:
http://localhost:8500/MTRestService/TranslatePost?tokenCode=0&input={ss}&srcLangCode=fr&trgLangCode=en&modelTag=
Other versions of Wordfast support inserting the project’s source and target language automatically into Custom MT URLs, but for some reason Wordfast Pro does not. Machine translations are generated only if a machine translation model has been installed for the specified language pair. You can check installed models from the Models tab of OPUS-CAT MT Engine.
When you have entered the values to the URL and JSON Key fields, close the Preferences window by clicking *OK, and open a file in the editor. The OPUS-CAT machine translation should now be displayed when a segment is opened:

The appearance of the first machine translation may take some time, as the MT model has to be initialized. Later translations will be produced faster. Machine translations can also be pregenerated for all segments by selecting the Use primary MT on no match segments checkbox in the project creation wizard:

Make sure to set Custom MT as the primary MT in the preferences before using this option.
Using OPUS-CAT in Wordfast Classic
Note: These instructions are for the current version of Wordfast Classic (8.85), courtesy of Jamie Lucero. Instructions for older versions of Wordfast Classic are available here.
- Make sure that OPUS-CAT MT Engine is running.
- Open Wordfast Classic user interface by pressing Ctlr+Alt+W in Word and select the Machine translation tab and the Customize MT subtab, and then select the MT name dropdown and choose Custom (add):

- Provide a preferred name, add the JSON key and URL (use the URL value below), and click Remote MT tab (or another tab) to initiate the save changes dialog:
http://localhost:8500/MTRestService/TranslateJson?tokenCode=&input={ss}&srcLangCode={sl}&trgLangCode={tl}
- After saving, select the new connection from the MT provider dropdown:

- You can now test OPUS-CAT by clicking the Test
button. If the test produced a translation, close the Wordfast Classic
user interface and open some source file. When you now open a segment,
Wordfast Classic should display a machine translation from OPUS-CAT
(unless a TM match is available):

Using OPUS-CAT with Wordfast Server
These instructions are also courtesy of Jamie Lucero. With Wordfast Server and Opus-CAT running on the same machine, Opus-CAT can be used from outside the LAN with a connection to Wordfast Server.
- Go to Setup and click MT Engines to add the MT Name and configure the rest:
URL: http://localhost:8500/MTRestService/TranslateJson Request data: tokenCode=&input={ss}&srcLangCode={sl}&trgLangCode={tl}&modelTag=
- Under Accounts, set up a new account or choose an existing one, then click the MT engine button to open the dialog and choose the desired engine:
