Designing a Multimodal-LLM Agent for Multi-Object Diffusion
Explore how to design a multimodal LLM agent that improves text-to-image generation by decomposing prompts, generating objects progressively, and using an internal feedback loop for self-correction. Understand how human interaction can enhance control and reliability in multi-object diffusion tasks through a structured agentic design framework.
In this lesson, we examine how an agentic system design can improve reliability and controllability in complex text-to-image generation tasks. Rather than relying on a single, one-shot model call, how to transform multi-object image generation into a structured, multi-step process managed by planning, execution, and feedback mechanisms.
The multi-object generation challenge
Modern text-to-image (T2I) models can generate high-quality images from a single prompt. However, when prompts require precise compositional reasoning, such as multiple objects, spatial relationships, and attribute bindings, one-shot generation might fail due to the inherent architectural limitation of a “one-shot” generative process. It lacks fine-grained control, interactivity, and a mechanism for self-correction. When a one-shot model fails to capture all the constraints in a complex prompt, our only option is to try again.
These potential failures highlight the need for a more robust and reliable process. This is where an agentic system design offers a different architectural approach. The core question for us as designers is not just “Can the model do it?” but also:
How can we make the generation process more reliable and less opaque?
How can we give the user (or the system itself) more control over the process?
How can the system correct its own mistakes as it goes? ...
