Building LLM Apps That Can See, Think, and Integrate: Using o3 with Multimodal Input and Structured Output

Advanced LLM applications can move beyond simple text by combining multimodal input, reasoning, and structured output. A practical example of this is a time-series anomaly detection system that visually analyzes charts of e-commerce data to find irregularities. The system uses OpenAI's `o3` model, which processes
