       - `--experimental-structured-mode array` Structures the input and output into a plain array format. This option is more concise compared to base mode, though it uses slightly more tokens per batch.
       - `--experimental-structured-mode object` Structures both the input and output into a dynamically generated object schema based on input values. This option is even more concise and uses fewer tokens, but requires smaller batch sizes and can be slow and unreliable. Due to its unreliability, it may lead to more resubmission retries, potentially wasting more tokens in the process.
   - `--experimental-use-full-context`  
-    Include the full context of translated data to work well with [prompt caching](https://openai.com/index/api-prompt-caching/). The length of the chunks is defined by `--history-prompt-length`. May risk running into the model's context window limit, typically `128K`, which should be sufficient for most cases.
