The Revolutionary Claims: What OpenAI Promised
PhD-Level Intelligence Across Multiple Domains
Overall, GPT‑5 is less effusively agreeable, uses fewer unnecessary emojis, and is more subtle and thoughtful in follow‑ups compared to GPT‑4o. It should feel less like "talking to AI" and more like chatting with a helpful friend with PhD‑level intelligence.
OpenAI's marketing positioned GPT-5 as a transformational upgrade with several key improvements:
Enhanced Reasoning: Automatic application of deeper thinking when complex problems require it
Reduced Hallucinations: 45% fewer factual errors compared to GPT-4o, and 80% fewer when using reasoning mode
Superior Performance: State-of-the-art results across mathematics, coding, and scientific problem-solving
Better Personality: Less sycophantic behavior and more natural, thoughtful responses
Multimodal Excellence: Significant improvements in visual perception and understanding

The Reality Check: User Experience Problems
Personality Changes Spark User Revolt
More than 4,000 people signed a Change.org petition to compel OpenAI to resurrect it. "I'm so done with ChatGPT 5," one user wrote on Reddit, explaining how they tried to use the new model to run "a simple system" of tasks that an earlier ChatGPT model used to handle. The user said GPT-5 "went rogue," deleting tasks and moving deadlines.
The user backlash was swift and significant:
Personality Complaints: Users found GPT-5 more terse, less friendly, and harder to work with
Workflow Disruptions: Existing automations and workflows broke with the personality changes
Emotional Disconnect: Loss of the conversational warmth that users had grown attached to
Functional Regressions: Some users reported worse performance on familiar tasks

Basic Error Problems Undermine "PhD-Level" Claims
Labeling basic maps of the United States also proved tricky for GPT-5 (but again, pretty funny, as tech writer Ed Zitron's post on Bluesky showed). GPT-5 did slightly better when I asked it on Wednesday for a map of the US. Some people can, in fact, label the great state of Vermont correctly without a PhD, but not GPT-5. And this is the first I'm hearing of states named "Yirginia."
Despite claims of PhD-level intelligence, users quickly discovered embarrassing errors:
Geography Mistakes: Incorrectly labeling US states on maps
Basic Factual Errors: Simple questions receiving confident but wrong answers
Inconsistent Performance: Brilliant on complex math but failing on elementary tasks
Reliability Issues: Unpredictable performance across different types of queries
