TLDR: VGTeam is an AI system that uses multiple communicative agents powered by large language models (LLMs) to automatically generate slideshow-style narrative videos from text prompts. It employs a “Chat Tower” workflow, API calls for multimedia, and achieves high success rates at low cost, making video production more accessible.
The world of video production is undergoing a significant transformation, driven by the rapid advancements in artificial intelligence. Traditionally, creating video content has been a resource-intensive and costly endeavor, often limited to those with substantial budgets and technical expertise. However, a new system called Video-Generation-Team, or VGTeam, is emerging to democratize this process, making high-quality video creation more accessible to a broader audience.
VGTeam is a novel slideshow video generation system that redefines the video creation pipeline by integrating large language models (LLMs). Instead of relying on conventional text-to-video models that often come with high computational costs, VGTeam employs a suite of communicative AI agents. Each agent is responsible for a distinct aspect of video generation, such as scriptwriting, scene creation, and audio design. These agents work together in a structured “Chat Tower” workflow, transforming a user’s textual prompts into coherent, slide-style narrative videos.
How VGTeam Works: The Chat Tower and Specialized Agents
At the heart of VGTeam’s efficiency is its “Chat Tower” architecture, which is inspired by the waterfall model used in software engineering. This structure ensures a sequential and organized dialogue among the agents. The user interacts primarily with the “agent director,” who then formulates specific tasks and objectives for other agents. These include the “editor,” “painter,” and “composer,” each carrying out their designated responsibilities in coordination to ensure the overall integrity of the production.
For instance, the agent editor generates video captions, which are then shared with the agent painter (for image prompts) and the agent composer (for music prompts) to maintain stylistic alignment across visual, auditory, and narrative elements. This role specialization is achieved through meticulous “prompt engineering,” where LLMs are given explicit instructions to guide their behavior according to their assigned roles, defining task objectives, input/output requirements, and performance standards.
To ensure continuity and prevent agents from “forgetting” previous instructions, VGTeam incorporates a “memory stream.” This subsystem captures and stores the outcomes of prior dialogues, providing agents with a reliable reference framework for informed decision-making. Furthermore, a crucial “iterative approval” mechanism is in place, where the agent director acts as a quality gatekeeper, reviewing outputs from other agents and providing feedback for refinement until the content meets the project’s quality standards.
API-Driven Efficiency and Performance
One of VGTeam’s key innovations is its reliance on API-based services for generating individual video components. This means the system interfaces with external APIs for image generation, voice synthesis, and music composition, eliminating the need for computationally intensive models to run locally. This API-centric strategy significantly lowers computational demands and broadens the applicability of LLMs in creative domains.
Experiments conducted with VGTeam demonstrated remarkable efficiency and scalability. The system successfully generated videos at an average cost of only $0.103 per video, achieving an impressive successful generation rate of 98.4%. The experiments also explored the impact of different large language models (like DeepSeek-V3, ERNIE 4.5-Turbo, and Qwen3-235B) and prompt lengths on performance. While longer prompts tend to yield higher-quality, contextually complete outputs, shorter prompts often result in more predictable and efficient system behavior, though with a slightly higher chance of output failure due to less context.

Implications and Future Directions
The implications of VGTeam are far-reaching. It not only democratizes video production by enabling broader access to high-quality content creation without extensive resources but also highlights the transformative potential of language models in creative fields. VGTeam is positioned as a pioneering system for next-generation content creation, offering a foundation for automating tasks like text-to-video generation and efficient production of slideshow videos.
While VGTeam represents a significant step forward, the researchers acknowledge limitations, including the inherent unpredictability of LLMs, the current reliance on static imagery with basic animation, and the need to address legal and ethical considerations such as copyright and content manipulation. Future work will focus on refining system stability, enhancing content complexity with more sophisticated visual technologies, and establishing clear guidelines for responsible AI application.
