- Changing Behavior of OpenAI’s ChatGPT Models ๐: A recent study by researchers from Stanford and UC Berkeley reveals that OpenAI’s large language models (LLMs), including GPT-3.5 and GPT-4, have shown shifts in performance and behavior between March and June 2023. Some tasks have experienced significant declines in performance over time. ๐ฎ๐
- Debating the Evaluation Metrics ๐: While the study suggests deteriorating performance, critics argue that the selected metrics may not accurately reflect the models’ capabilities. There are concerns that the evaluation might mistake mimicry for reasoning. Discussions among experts and users bring to light the complexities of assessing LLM behavior. ๐ค๐
- The Importance of Monitoring and Transparency ๐ต๏ธ: The research highlights the need for continuous external assessment and monitoring of LLMs to understand changes in behavior, referred to as “LLM drift.” Transparency and vigilance in tracking model updates can help businesses and users adapt, preventing potential disruptions to workflows and applications. ๐โ
Supplemental Information โน๏ธ
The study acknowledges the limitations of an unreviewed paper and emphasizes the significance of peer review for further validation. It also raises questions about the evolution of closed LLMs over time and the lack of information from vendors about model updates. The concept of LLM drift and the need for improved transparency emerge as crucial considerations in the field of generative AI models.
ELI5 ๐
The researchers found that the behavior of OpenAI’s ChatGPT models has been changing, and some tasks have become harder for the models to perform over time. However, some experts question whether the chosen evaluation methods truly reflect the models’ abilities. Monitoring and transparency are crucial to understand these changes and make sure the models work well for users. ๐ค๐
