DeepSeek AI Translation Channel
What is it?
DeepSeek is a well-known AI platform that offers high-quality language models. Since version 3.74, pyVideoTrans has integrated DeepSeek as a standalone translation channel. It uses an OpenAI-compatible interface, provides excellent translation quality, and supports deep thinking (reasoning) mode — making it a great choice for users who need top-tier translations.
