GPT-5 Bugs & Issues 2026 - Complete Bug Tracker

Live tracker of every known GPT-5 bug: coding failures, hallucinations, throttled output, and broken features OpenAI won't acknowledge.

Ongoing documentation of GPT-5 issues as they emerge, including regressions, new failure modes, and user-reported problems.

From launch day hype to user revolt: the complete chronological timeline of everything that went wrong with GPT-5.

The 5.2 update was supposed to fix GPT-5's problems. Instead it introduced new ones and made the writing quality measurably worse.

Detailed technical review of GPT-5.2's capabilities and failures, with side-by-side comparisons to GPT-4o and GPT-5.

When OpenAI killed GPT-4o, users who had formed deep emotional bonds with the model experienced genuine grief and loss.

The psychological fallout from retiring GPT-4o was severe enough to trigger safety concerns and crisis intervention discussions.

Comprehensive evidence documenting ChatGPT's measurable quality decline across coding, reasoning, and creative writing tasks.

Users aren't imagining it. Benchmark data and controlled testing confirm ChatGPT's capabilities have degraded over time.

The question millions of users are asking, answered with data, user reports, and Stanford research confirming the decline.

OpenAI quietly reduces model capabilities without telling users. Documented cases of features disappearing overnight.

Developers report that AI code generation has gotten significantly worse, producing more bugs and less functional output.

Studies show AI coding tools make developers feel faster while actually introducing more bugs and technical debt.

The most dangerous AI coding bugs are the ones that compile and run but produce subtly wrong results no one catches.

Why ChatGPT forgets what you said 10 messages ago, and how context window limitations cause cascading failures.

The internet is filling up with AI-generated content. When AI trains on that content, quality collapses irreversibly.

LLMs don't think. They predict the next token. This fundamental limitation explains most of ChatGPT's failures.

The organized boycott that started with OpenAI's Pentagon deal and grew into the largest user revolt in AI history.

More than 1.5 million users cancelled ChatGPT subscriptions in March 2026. What drove the exodus and where they went.

A blunt assessment of everything wrong with ChatGPT in 2026, from degraded performance to ethical failures to broken trust.
