-| `3009` | Formatting |Complex tables and charts can present significant challenges during translation, especially when they're large and intricate. Charts and tables with mixed horizontal and vertical text, varying cell sizes, or grid structures that are borderless, are difficult to format accurately. These types of tables may require added processing to ensure precision without compromising overall performance. | To improve the quality of translation output, consider recreating documents using bordered tables and charts rather than borderless ones. |April 1, 2025  |

 | `3008` | File types  | Translating complex documents | Translating documents with thousands of intricate pages can be challenging. These documents often include images, embedded text within images, and manually typed text. As a result, the batch translation request can encounter failures during the extraction, translation, and reassembly processes.| Split the large document into smaller sections (for example, divide a 1000-page file into approximately 10 files of 100 pages each) and submit them individually for the best results.| February 5, 2025|
 | `3007` | Content| Translating documents with mixed source languages  | In some cases, document translation doesn't translate source documents with multiple languages leading to incorrect or incomplete results. For example, a sentence that contains more than one language.| To ensure that the desired language is translated to the target language, specify the intended source language. Alternatively, remove the mixed-language sentence, or split the text into segments containing only one language. | February 5, 2025|
 | `3001` | Formatting  | Formatting of mathematical expressions| In some cases, translated documents don't fully retain the formatting of mathematical expressions. Superscript and subscript numbers can be reformatted incorrectly, leading to discrepancies between expected and actual output.   | Currently, there's no direct workaround. Users should manually adjust the formatting of mathematical expressions as needed.  | February 5, 2025|
