AI Agents Generating Slides: Letting the Model See Its Own Layout
The 2026 consensus for agent-built slide decks: outline-first, separate content from construction, then render to images and let a fresh-eyes subagent do visual QA. Anthropic's and OpenAI's official slides skills both converged on PptxGenJS plus a visual verification loop, and the research line (PPTAgent → PreGenie → DeepPresenter) points the same way. But two later corrections matter: PresentBench shows the widely cited PPTEval scores too generously, and SeaSlides argues the model should not write free-form HTML/SVG at all.
