Title: OpenAI’s GPT-4 Faces Performance Challenges Amidst Redesign Speculations
OpenAI’s highly acclaimed AI model, GPT-4, has recently come under fire for a decline in its performance. Users have been voicing their frustrations, describing the model as lazier and dumber compared to its previous versions.
Numerous complaints have surfaced on platforms like Twitter and OpenAI’s online developer forum, citing issues such as weakened logic, erroneous responses, difficulty following instructions, and even forgetting to include brackets in software code. Users have expressed disappointment, with one developer stating, It’s like driving a Ferrari for a month then suddenly it turns into a beaten-up old pickup truck. I’m not sure I want to pay for it.
Peter Yang, a product lead at Roblox, took to Twitter to share his experience, mentioning that while GPT-4 generated outputs faster, the quality had noticeably declined. Other users echoed this sentiment, with one user, Frazier MacLeod, claiming the model had become lazier.
OpenAI’s developer forum also witnessed comments from users like Christi Kennedy, who noted that GPT-4 had begun looping outputs repeatedly, leading her to conclude that it had become braindead compared to its previous capabilities.
OpenAI had initially impressed the world with its ChatGPT, which ran on GPT-3 and GPT-3.5. The launch of GPT-4 in March created high anticipation within the tech industry due to its multimodal nature, enabling it to comprehend both images and text inputs. It swiftly became a go-to model for developers and industry insiders, being touted as the most powerful AI model available.
However, enthusiasm waned when users started receiving unexpectedly high bills for using GPT-4. While the model was accurate, it was slow. This made many users speculate that a significant redesign of the system was underway.
Industry experts, including Sharon Zhou, CEO of Lamini, believe that OpenAI may be developing multiple smaller GPT-4 models known as a Mixture of Experts (MOE). Zhou explains that each expert model could be trained on different tasks and subjects, resulting in specialized models like mini biologist GPT-4 or physics GPT-4. When a user poses a question, the system can direct it to the appropriate expert model, or even multiple models for better results.
This approach, according to Zhou, allows OpenAI to reduce costs while maintaining performance. She draws an analogy to the Ship of Theseus thought experiment, where parts of a ship are gradually replaced, sparking a debate about when it becomes an entirely new ship. Zhou suggests that OpenAI is essentially transforming GPT-4 into a fleet of smaller models.
OpenAI has yet to respond to inquiries regarding the speculations surrounding GPT-4’s changes.
In recent weeks, leaked details about GPT-4’s architecture have emerged on platforms like Twitter. Yam Peleg, a startup founder, claimed that OpenAI employed a 16-expert MOE model to control costs. While there is no official confirmation, the leaks align with OpenAI’s previous research papers and statements discussing the MOE approach.
It is speculated that GPT-4’s decline in performance could be linked to OpenAI gradually rolling out these smaller expert models, gathering user data to improve and learn over time.
Although users may find GPT-4’s current performance underwhelming, the potential benefits of OpenAI’s MOE approach may outweigh the initial setbacks. As OpenAI continues to refine its AI models, the industry eagerly awaits the fruition of these developments and their impact on future AI advancements.
