I'm not sure how to add this feature, I thought Layout Analysis is an api so it should go in model_runtime, but according to the documentation it only supports models that can do the following tasks.

LLM - LLM text completion, dialogue, pre-computed tokens capability Text Embedding Model - Text Embedding, pre-computed tokens capability Rerank Model - Segment Rerank capability Speech-to-text Model - Speech to text capability Text-to-speech Model - Text to speech capability Moderation - Moderation capability
