Core Insights - DeepL has announced significant updates to its API, introducing a self-developed AI language model and a writing assistant called DeepL Write, aimed at enhancing translation and writing support capabilities [1][2]. Group 1: DeepL Write - DeepL Write is positioned as a professional writing assistance tool, similar to Grammarly, focusing on improving text quality rather than generating new content [2]. - The tool provides real-time language optimization suggestions, including grammar correction, wording adjustments, and style adaptation, helping users produce more standardized and fluent text [3]. Group 2: AI Language Model - The newly developed language model primarily serves translation scenarios, correcting and optimizing translation results [3]. - It demonstrates deep semantic understanding, allowing for accurate recognition of proper nouns and culturally specific expressions, significantly enhancing reliability in complex translation tasks, especially for specialized terminology and sensitive content [3]. Group 3: API and Language Support - The DeepL API now supports 33 languages, including English, Dutch, Swedish, Japanese, German, Korean, and Simplified Chinese, covering major global language systems [3]. - DeepL has committed to not using user-submitted content for model training, ensuring data security and privacy protection from both technical and operational perspectives [3].
