Please provide the details：

* **Use Case**: Specific application (e.g., batch image captioning, customer support chat).
* **Scale**: Estimated daily request volume.
* **Performance**: Requirements for response speed (latency) and output quality.
* **Budget**: Target cost constraints or optimization goals.

<Accordion title="Case Study: Batch Image Captioning">
  **Customer Requirement:** Need to generate descriptive captions for a large volume of product images.

  **Recommended Solutions:**

  * GPT 5.4 Mini: Low cost, stable quality, ideal for batch processing
  * Gemini 3.5 Flash: Fast speed, lower cost, perfect for ultra-large scale

  **Rationale:** This task requires consistent descriptive accuracy rather than high-level creativity. Since it is highly sensitive to **cost and speed**, the Mini and Flash series provide the optimal **price-to-performance ratio**.
