Sibyl: An AI Agent Structure Created to Improve the Ability of LLMs in Intricate Logical Tasks

Large language models (LLMs) can revolutionize human-computer interaction but struggle with complex reasoning tasks, a situation prompting the need for a more streamlined and powerful approach. Current LLM-based agents perform well in straightforward scenarios but struggle with complex situations, emphasizing the need for improving these agents to tackle an array of intricate problems.

Researchers from Baichuan Inc. and Tianjin University’s College of Intelligence and Computing have introduced Sibyl, a robust LLM-based agent designed to navigate complex reasoning tasks. It combines four main modules — a tool planner, an external information acquisition channel, a multi-agent debate-based jury, and a global workspace — that focus on information retention, problem-solving, and self correction.

Sibyl, based on functional programming principles, uses question and answer (QA) functions instead of dialogues, thus paving the way for the independent operation of reasoning tasks. This approach enhances the structure of the agent while simplifying debugging processes. Its functionality was tested on the GAIA benchmark test set, which showcases Sibyl’s high performance, particularly in challenging scenarios. It proves the significant potential Sibyl has in solving complex reasoning tasks, pushing LLM-based applications towards deliberate System-2 thinking.

Sibyl’s design philosophy places important emphasis on enhancing complex reasoning capabilities while reducing the overall complexity. It uses a human-oriented browser interface, maintaining depth of data while simplifying system architecture and enabling easy maintenance. The framework functions primarily around a Web browser and Python environments, facilitating simpler human-computer interactions.

The framework also focuses on enhancing capacities for long-term memory, planning and error correction. Sibyl maintains a shared global workspace across all modules and uses a state-based representation language to compress and store relevant information. It uses a multi-agent debate format, known as a Jury mechanism, to enhance error correction efficiency. The information stored on the shared platform is utilized to refine responses and ensure problem-solving accuracy.

Sibyl’s performance surpasses other models, for example, GPT-4, AutoGPT-4, AutoGen, and FRIDAY, even in complex Level 2 and Level 3 scenarios, minimizing error propagation and demonstrating complex reasoning capabilities. The accuracy rates decrease less from validation to the test set as compared to other models. Sibyl also solves problems quicker than human reasoning in equivalent situations.

Despite being limited to a maximum of 20 reasoning steps, Sibyl effectively narrows unnecessary inference processes and suppresses error propagation, opening the way for the development of versatile and capable LLM applications. As AI continues to evolve, Sibyl’s framework promises a solution to the gap between current AI capabilities and the intricacies of multi-step reasoning processes required in real-world scenarios. The credit for this research goes to the researchers of this project, and more can be learned from the research paper.
