Google’s new diffusion AI agent mimics human writing to improve enterprise research


A diffusion model inspired by the human process of drafting, searching for information, and making iterative revisions.

As Han notes, since the model was evaluated on helpfulness, which includes fluency and coherence, the performance gains are a direct measure of its ability to produce well-structured business documents. To build and test their framework, the researchers used Google’s Agent Development Kit(ADK), an extensible platform for orchestrating complex AI workflows, with Gemini 2.5 Pro as the core LLM (though you can swap it for other models). A similar “test-time diffusion” process could be used to generate complex software code, create a detailed financial model, or design a multi-stage marketing campaign, where an initial “draft” of the project is iteratively refined with new information and feedback from various specialized tools.
