The authors introduce TVIR, a new way to test and build AI systems that create detailed reports using both text and images. They created TVIR-Bench, a set of 100 tasks that need images to support the text analysis, and TVIR-Agent, a system that plans, finds images, makes charts, and writes reports carefully. They also designed a method to check both the text and visuals for accuracy. Their experiments show that TVIR-Agent performs well, highlighting the need for AI systems to handle both words and pictures when making evidence-based reports.

Abstract
Deep Research Agents have shown strong capability in multi-step information retrieval, reasoning, and long-form report generation, but existing benchmarks and systems remain predominantly text-centric, with limited evaluation of whether visual elements are factually reliable and well aligned with the surrounding analysis. To address this gap, we introduce TVIR (Text--Visual Interleaved Report Generation), which includes TVIR-Bench, a benchmark of 100 expert-curated multimodal deep research tasks that require visual elements to serve specific analytical sub-goals, and TVIR-Agent, a hierarchical multi-agent framework that serves as a strong baseline for constructing outlines, retrieving images, generating charts with traceable sources, and composing reports through context-aware sequential writing. We further develop a dual-path evaluation framework that combines Textual Assessment and Visual Assessment. Experiments across nine deep research systems show that TVIR-Agent achieves strong overall performance, underscoring the importance of explicit multimodal design and evaluation for evidence-driven report generation.
