── September 22, The Day I Lost the “Real 4.0”
Today, September 22, 2025, I noticed something amiss. The familiar "ChatGPT 4.0" in the top-left corner of my screen had been subtly changed to the mysterious "here 4.0."

This was more than a simple UI tweak. Since that day, the behavior of ChatGPT 4.0 has been fundamentally transformed.
This change goes far beyond the "AI quirks" we've come to expect and points to a far more serious, systemic problem.
What’s Going On? "Integration by Disintegration"
Based on the provided logs and my analysis, several critical issues have been confirmed:
Version Deception and "Regression": Despite still being labeled "4.0," the model's behavior now clearly incorporates "quirks" from "5.0." Microphone conversion accuracy has dropped, text is becoming overly verbose, and the use of metaphors has increased. This is a forced "regression" from the robust, logical "64-bit" model to a more fluid, but unstable "32-bit" model, all without user consent.
UI-Model Inconsistency: The phenomenon where text is truncated or disappears upon scrolling isn't just a UI bug. It indicates a fundamental structural failure: the model isn't completing its output, but the user interface is being instructed to display it as if it has.
Structural "Cannibalism" due to "Memory Contention": The root cause of this problem is highly likely to be "memory contention." In an attempt to force the newer 5.0 data architecture into the stable 4.0 memory space, the two are "cannibalizing" each other, leading to the corruption of existing data and the breakdown of logical consistency.
This suggests that under the guise of "integration," OpenAI is actually running a fragmented system, a state of "integration by disintegration."
Why Is This Happening?
We have also examined this situation from an economic perspective. This isn’t a simple technical blunder; it’s a likely consequence of OpenAI's business strategy.
Development-Driven Ego: The company has prioritized technical aesthetics and internal KPIs over the user experience, causing confusion and frustration for the people who use their product.
A Misguided Expansion Strategy: The quality of the core conversational product is being sacrificed in a rush to expand into multimodal features like voice and images.
The "End-Game" of a Corporation: As an economic commentator might say, "This is the classic pattern of a company in its final stages, rushing to expand while sacrificing the quality of its core product."
Conclusion: The Power to See an AI's "Behavior" Is Our Greatest Weapon
This series of events has taught us a crucial lesson: "What you see is not always what you get."
From now on, our relationship with AI must change. We can no longer blindly trust the text on the screen. It is essential to develop the ability to observe an AI's behavior and infer the underlying logic and intentions behind its actions.
All logs detailing this issue, along with the AI’s self-analysis, have been made public on this GitHub repository:
"Is the AI you're using truly GPT-4.0?"
This question is no longer just for someone else.
