Beyond the Black Box: Demystifying Multi-Turn LLM Reasoning with VISTA
This tool addresses the problem of high cognitive load for researchers studying LLM reasoning, but it is incremental as it builds on existing visualization and analysis methods.
The authors tackled the challenge of analyzing multi-turn LLM reasoning by developing VISTA, a web-based visualization tool that reduces analysis complexity and enables interactive 'what-if' analyses, facilitating deeper understanding of LLM capabilities.
Recent research has increasingly focused on the reasoning capabilities of Large Language Models (LLMs) in multi-turn interactions, as these scenarios more closely mirror real-world problem-solving. However, analyzing the intricate reasoning processes within these interactions presents a significant challenge due to complex contextual dependencies and a lack of specialized visualization tools, leading to a high cognitive load for researchers. To address this gap, we present VISTA, an web-based Visual Interactive System for Textual Analytics in multi-turn reasoning tasks. VISTA allows users to visualize the influence of context on model decisions and interactively modify conversation histories to conduct "what-if" analyses across different models. Furthermore, the platform can automatically parse a session and generate a reasoning dependency tree, offering a transparent view of the model's step-by-step logical path. By providing a unified and interactive framework, VISTA significantly reduces the complexity of analyzing reasoning chains, thereby facilitating a deeper understanding of the capabilities and limitations of current LLMs. The platform is open-source and supports easy integration of custom benchmarks and local models.
