Wyvern: An Agentic Framework for Generating Grounded Multimodal Reports
The paper introduces Wyvern, a multi-agent framework that automates the creation of grounded, multimodal technical reports by integrating text, images, and tables with verified references, demonstrating superior informativeness, utility, and citation accuracy compared to existing baselines.

Imagine you are trying to keep up with the entire internet. New articles, research papers, and blog posts are popping up every second, faster than any human brain could possibly read them all. It's like trying to drink from a firehose while someone keeps turning up the pressure. In the world of artificial intelligence, scientists are building "smart" computers (called Large Language Models) that can read and write. But there's a catch: these computers sometimes make things up or forget where they got their information. This is like a student who writes a great essay but can't tell you which books they used, or worse, invents facts that sound real but aren't. To fix this, researchers are teaching these computers to be "grounded," meaning every sentence they write must be backed up by a real source they found, like a student who always cites their sources. The big question is: can we build a team of these smart computers that not only writes a report but also finds the pictures, checks the facts, and makes sure everything is true?
Enter Wyvern, a new digital team of robot assistants designed to solve this exact problem. Think of Wyvern not as a single robot, but as a bustling newsroom where every worker has a very specific job. When you ask Wyvern to write a report on a topic—say, "How do solar panels work?"—it doesn't just start typing. First, a team of "Scouts" goes out onto the internet to find the best articles and websites. They don't just grab anything; they check if the articles are complete and if they actually talk about solar panels. If they find a link inside an article that looks interesting, they follow it, digging deeper until they have a huge pile of reliable information.
Next, the "Architects" step in. They look at all that information and build a plan, deciding what the report should look like and what sections it needs. Then, the "Writers" get to work, filling in the details. But here is where Wyvern gets really cool: it doesn't just write text. It acts like a graphic designer too. It hunts down the best charts and diagrams from the articles it found, decides exactly where they should go in the report to make the most sense, and even writes captions for them. It's like having a team that can write a story and simultaneously design the perfect illustrations to go with it, all in one go.
But the most important part of Wyvern is its "Fact-Checkers." Before the report is finished, a special team of agents reads every single sentence and asks, "Can you prove this?" They look at the sources the report is supposed to be based on. If a sentence says, "Solar panels are 90% efficient," the Fact-Checkers go back to the source to see if that number is actually there. If it's not, or if the source doesn't fully support the claim, the Fact-Checkers either fix the sentence or delete it entirely. This ensures the final report is "grounded," meaning it's built on solid evidence, not on guesses.
The researchers tested Wyvern by having it write reports on various topics and comparing them to reports made by other famous AI tools. They asked real humans—experts and students—to read the reports and pick the best one. The results were impressive. In 87% of the cases, people thought the pictures and charts in Wyvern's reports were more informative than those in the other tools' reports. When it came to how useful the whole report was, Wyvern was rated as the best choice between 63% and 100% of the time, depending on which competitor it was up against. The computer tests also showed that Wyvern was much better at making sure every claim had a proper citation, improving its accuracy by up to 2.3 times compared to the others.
However, the creators are careful to say that Wyvern isn't perfect yet. Sometimes the reports can be a bit too long or repetitive, and if the original articles on the internet have bad information, Wyvern might accidentally include it because it trusts the sources it finds. It's a powerful tool that helps us navigate the flood of information, but it still needs human eyes to double-check the final product. The paper suggests that while automatic tools are getting better at checking themselves, they still need a little help from us to be truly reliable.
