In this video, we demonstrate how to set up translation with ChatGPT in Trados, and how to customize the output with Custom.MT Console.

Custom.MT Console is a machine translation platform integrated with Trados, memoQ, and Smartling. It allows you to create, manage, and use your own custom machine translation (MT) models, and to connect with large language models such as OpenAI GPT-4, GPT-4o, and GPT-4-Turbo for translation and post-editing.

You can customize GPT machine translation output with prompts and glossaries, allowing them to produce translations that align more closely with your organization’s terminology and style. You can also adjust to the reader, and specify their preferred level of text complexity, formal or informal voice, and gender.

In the video below you will find some useful post-editing prompts that you can start your experiments with and advice on how to customize them to better fit your desired outcome:
