OpenAI Shuts Down Inaccurate AI Detection Tool Decrypt: OpenAI acknowledged Decrypt's low accuracy and potential harm, leading to its discontinuation. Some analysts warn of a potential AI stock market bubble.
OpenAI has discontinued its AI detection tool, Decrypt, due to its low accuracy. The tool, which was designed to identify AI-generated text, was not reliable, with false positives potentially causing significant harm. While OpenAI had previously acknowledged the limitations of the tool, the decision to shut it down was made to prevent further inaccuracies and potential damage. The stock market's growth, fueled by AI mania and investments in companies like Nvidia, has some analysts concerned about a potential bubble. OpenAI's AI classifier, which was announced in January, was not able to accurately identify AI-generated text, with only 26% true positives and 9% false positives. The consequences of incorrectly labeling human-written text as AI-generated can be damaging, as seen in May when a Texas professor incorrectly accused his students of using ChatGPT to write their papers. OpenAI has committed to developing more effective provenance techniques and mechanisms to help users understand if content is AI-generated. Meanwhile, some analysts are worried that the high stock prices of AI-related companies, such as Nvidia, could lead to a bubble and a subsequent market downturn.
AI's Impact on Markets: Hype vs. Reality: JPMorgan warns of disparity between AI hype and real earnings growth, while broader factors like interest rates, savings, and geopolitics may also impact markets. AI is making strides in art research and ancient mummy reconstruction.
While there is growing hype around AI and its potential impact on markets, JPMorgan raises concerns about the disparity between AI hype and real earnings growth. The firm also suggests that broader factors, such as higher interest rates, erosion of personal savings, and geopolitical tensions, may be underestimated by markets. Meanwhile, in the realm of research, a study published in the Proceedings of the National Academy of Sciences suggests that the memorability of art may have less to do with subjective experiences and more to do with the artwork itself, as determined by a deep learning neural network. Lastly, the Egypt Ministry of Tourism and Antiquities is using AI in partnership with radiological techniques to reconstruct ancient mummies. Overall, these developments underscore the increasing role of AI in various sectors, from finance to art and archaeology, while also highlighting the need for a nuanced understanding of its potential impact.
Perceived decline in ChatGPT performance: Users report lower quality responses, but OpenAI denies changes. Consider using alternative tools for effective 1:1 meetings.
There has been a perceived decline in the performance of ChatGPT, as reported by various users and discussed extensively online. This includes concerns about the quality of responses, particularly in coding, and a shift towards more superficial or cookie-cutter answers. However, OpenAI has repeatedly denied making any changes to make ChatGPT dumber, and some speculate that this could be due to cost-saving measures or other factors. Despite the ongoing debate, it's clear that many users have noticed a change and are seeking alternative tools or approaches. It's important for businesses and individuals to stay informed about the latest developments in AI and how they may impact their workflows and productivity. To make the most of your 1:1 meetings, consider using tools like Supermanage, which can help you prepare for meaningful conversations by providing real-time briefs on your team's Slack channels.
Decline in Language Model Performance: An Issue of Concern: Reports of worsening Chat gpt and GPT 4 performance, confirmed by research, highlight the importance of continuous monitoring and evaluation to ensure consistent, reliable, and high-quality language model output. OpenAI and other organizations should address these issues to provide accurate and effective models for users.
The performance of language models like Chat gpt and GPT 4 from OpenAI can significantly degrade over time, leading to inconsistent and unreliable results. This was evident from various reports of worsening performance and anecdotal evidence from regular users. For instance, Logan from OpenAI's developer relations team acknowledged the issue and encouraged users to create evaluations (evals) to test model quality and identify potential regressions. A poll conducted by Josha Bach revealed that about 42.5% of respondents had noticed a decline in Chat gpt's performance. Moreover, a research paper from Stanford and UC Berkeley confirmed these findings by testing GPT 3.5 and GPT 4 on four separate tasks between March and June 2023. The results showed substantial changes in performance and behavior for both models. For instance, GPT 4's accuracy in identifying prime numbers dropped from 97.6% to 2.4%, while GPT 3.5's accuracy improved from 7.4% to 86.8%. Similarly, GPT 4 became less willing to answer sensitive questions, and the code generated by both models became less directly executable. These findings underscore the importance of continuous monitoring and evaluation of language model performance to ensure consistency, reliability, and high-quality output. OpenAI and other organizations developing language models should take proactive steps to address these issues and provide users with up-to-date, accurate, and effective models to help them achieve their goals.
Identified drift issues in GPT 4's performance in visual reasoning: Researchers found concept and data drift in GPT 4's visual reasoning, but interpretations of its worsened performance are oversimplified, and evaluation methods were criticized.
The performance of GPT 4 and GPT 3.5 in visual reasoning remained similar with slight increases between March and June, but researchers have identified two types of drift: concept drift and data drift. Concept drift refers to changes in the relationship between input variables and the output variable, while data drift refers to changes in the distributions of input variables. However, interpretations of a recent research paper suggesting that GPT 4 has worsened since its release are oversimplifications, as the capability of the model should remain consistent, but its behavior can vary. The researchers also criticized the evaluation methods used in the paper, particularly in the assessment of math problems and code generation. The March version of GPT 4 almost always guessed primes as prime numbers, while the June version almost always guessed composites, leading to perceived performance degradation. For cogeneration, the newer GPT 4 model was criticized for adding noncode text to its output without evaluating its correctness. Overall, while the findings are interesting, it's important to consider the limitations and potential biases in the research methods.
Challenges of Building Applications on Top of Large Language Models: Users face frustration when LLMs' behavior changes, requiring them to adjust workflows and prompting strategies, and the lack of transparency from OpenAI makes it difficult to build dependable software on top of these models.
The new research paper on ChatGPT does not definitively prove intentional performance degradation, but it does highlight the challenges of building applications on top of large language models (LLMs) due to their non-deterministic nature and frequent behavior changes. Users develop specific workflows and prompting strategies that work best for their use cases, and when there's a behavior drift, those strategies might no longer be effective. This can lead to frustration and the need to redefine workflows to get better results. The lack of transparency and release notes from OpenAI regarding their models' changes only adds to the uncertainty and challenges for developers building dependable software on top of them. Ultimately, the question of whether ChatGPT has actually gotten worse or just appears worse remains unanswered, but the frustration and potential need for workflow adjustments are real for many users. AI researcher Simon Willison's comments on the lack of transparency may be the most significant issue, making it difficult to build reliable software on top of LLMs that change in undocumented ways every few months.
