DeepPresenter: Environment-Grounded Reflection for Agentic Presentation Generation

2026-04-16 · Source: cs.AI updates on arXiv.org · Field: Technology & Digital — Artificial Intelligence & Machine Learning, Robotics & Autonomous Systems · Depth: Expert, extended

Summary

DeepPresenter is an agentic framework designed to automate presentation generation by adapting to diverse user intents and enabling effective feedback-driven refinement. Unlike existing systems that rely on predefined workflows and fixed templates, DeepPresenter coordinates two specialized agents: a Researcher for content compilation and a Presenter for visual slide design. It introduces "environment-grounded reflection," where agents inspect rendered slide artifacts and structured manuscript diagnostics to identify and correct post-render defects like overlapping elements or truncated text. The framework achieves state-of-the-art performance, scoring 4.44 with proprietary backbones like Gemini-3-Pro, surpassing commercial systems like Gamma (4.36). A fine-tuned, more efficient version, DeepPresenter-9B, scores 4.19, outperforming all open-source baselines and approaching GPT-5 (4.22) at a substantially lower cost. The system's effectiveness is attributed to its dual-agent collaboration and environment-grounded reflection, which significantly improves content quality, visual style, and diversity.

Key takeaway

For research scientists developing AI agents for complex, multi-modal tasks, DeepPresenter demonstrates the critical value of integrating environment-grounded reflection. You should consider designing your agents to inspect rendered outputs or perceptual states, not just internal reasoning traces, to catch and correct defects that only manifest post-render. This approach, combined with specialized agent roles, can significantly enhance output quality and adaptability, even with smaller, fine-tuned models.

Key insights

Environment-grounded reflection and dual-agent collaboration enable AI to generate high-quality, adaptable presentations with fewer post-render defects.

Principles

• Decouple content research from visual design.
• Ground reflection in perceptual artifact states.
• Mitigate self-verification bias with extrinsic feedback.

Method

DeepPresenter uses a Researcher agent for manuscript creation and a Presenter agent for HTML slide generation. Both agents utilize an "inspect" tool to observe rendered artifacts and a "think" tool to plan targeted revisions, forming an observe-reflect-revise loop.

In practice

• Use "inspect" tools to expose post-render defects.
• Employ extrinsic verification during training to improve agent self-correction.
• Decompose complex tasks into specialized agent roles.
