Why OpenAI Assistants is a Big Win for LLM Evaluation

Confident AI's JudgementalGPT is an LLM agent built using OpenAI's Assistants API designed for evaluating other LLM applications, providing more accurate and reliable results compared to state-of-the-art approaches like G-Eval. However, the limitations of LLM-based evaluations include unreliability, inaccuracy, and bias, which can be addressed by having multiple evaluators that perform different evaluations depending on the evaluation task at hand. JudgementalGPT is a proxy for multiple assistants that account for tasks prone to logical fallacies and provide more guidance based on user feedback. Despite its advantages, problems with LLM-based evaluation still linger, including accuracy challenges stemming from single-digit scores and intricacies in defining evaluators. The key to building a better evaluator lies in tailoring them for specific use cases, leveraging OpenAI's Assistant API and code interpreter functionality.
