Main AI News:
OpenAI has taken a bold stance against the issue of AI “hallucinations,” unveiling a novel approach to training artificial intelligence models. In the midst of an AI boom and the lead-up to the 2024 U.S. presidential election, the spread of misinformation propagated by AI systems has become a subject of intense debate. OpenAI aims to address this concern head-on.
Last year, OpenAI made waves in the industry with the launch of ChatGPT, a chatbot driven by the powerful GPT-3 and GPT-4 models. Within a mere two months, the app garnered over 100 million monthly users, setting an impressive record for the fastest-growing application. Microsoft has shown its faith in OpenAI’s potential by investing more than $13 billion in the company, catapulting its valuation to an astounding $29 billion.
AI hallucinations occur when models like OpenAI’s ChatGPT or Google’s Bard fabricate information, misleadingly presenting it as factual. For instance, Google’s promotional video for Bard featured a claim about the James Webb Space Telescope that turned out to be false. Similarly, ChatGPT was involved in referencing “bogus” cases in a New York federal court filing, potentially leading to sanctions for the attorneys involved.
In their report, the OpenAI researchers expressed concern over the propensity of even state-of-the-art models to generate falsehoods, particularly in domains that require complex reasoning. A single logical error can undermine an otherwise robust solution. OpenAI’s proposed strategy to combat such fabrications involves training AI models to reward themselves for each correct step of reasoning they take toward arriving at an answer, rather than solely rewarding a correct final conclusion. This new approach, termed “process supervision,” could pave the way for more explainable AI systems, as it encourages models to follow a more human-like chain of “thought.”
Karl Cobbe, a mathgen researcher at OpenAI, emphasized the significance of detecting and mitigating logical mistakes, or hallucinations, in the pursuit of building aligned AGI (artificial general intelligence). Although OpenAI did not originate the process-supervision approach, the company aims to drive its advancement. Cobbe highlighted that the research aims to address hallucinations and enhance models’ problem-solving capabilities.
To support their research, OpenAI has released a comprehensive dataset comprising 800,000 human labels, which were employed to train the mentioned model. However, Ben Winters, senior counsel at the Electronic Privacy Information Center, expressed skepticism regarding the effectiveness of the dataset alone in mitigating concerns about misinformation and incorrect results in real-world scenarios. Winters urged a thorough examination of the complete dataset and accompanying examples before forming any concrete judgments. He further raised questions about OpenAI’s willingness to release their findings to the public and incorporate them into their products.
Suresh Venkatasubramanian, director of the Center for Technology Responsibility at Brown University, viewed the OpenAI paper as more of a preliminary observation, emphasizing the need for validation and consensus within the research community. Given the variability of large language models, he cautioned against assuming that what works in one context will necessarily work in another. Venkatasubramanian highlighted the concern of models conjuring up citations and references, noting that the paper lacks evidence to support the effectiveness of the proposed approach in addressing this particular issue.
Karl Cobbe stated that the company intends to submit the paper for peer review at an upcoming conference. However, OpenAI has not provided a comment regarding when, or if, they plan to implement the new strategy in ChatGPT and other products. Sarah Myers West, managing director of the AI Now Institute, welcomed OpenAI’s effort to refine its systems and reduce errors.
She emphasized the need to perceive this research as part of corporate initiatives, acknowledging the existing barriers to achieving more comprehensive forms of accountability in the field. West pointed out that although OpenAI has released a small dataset of human-level feedback with the paper, they have not provided essential details about the training and testing data used for GPT-4, leaving significant gaps in transparency and hindering meaningful accountability efforts in the field of AI, despite these systems already directly impacting people’s lives.
Conclusion:
OpenAI’s strategy to combat AI “hallucinations” and improve model reasoning represents a significant development in the AI market. By rewarding models for correct reasoning steps, OpenAI aims to address the generation of falsehoods and enhance the problem-solving capabilities of AI systems. This approach aligns with the growing demand for more explainable AI and can have a positive impact on various domains, including those requiring complex reasoning.
However, concerns regarding the effectiveness of the dataset and the transparency of OpenAI’s findings may influence the market’s perception of their products. The ongoing research and validation within the community will be crucial in determining the viability and practical implementation of OpenAI’s proposed approach. Overall, this development underscores the importance of accountability and transparency in the AI industry and signals a step towards more reliable and trustworthy AI systems.
