OpenAI co-founder and CEO Sam Altman is publicly acknowledging main hiccups in yesterday’s rollout of GPT-5, the corporate’s new, flagship giant language mannequin (LLM) — marketed as its strongest and succesful but.
Answering consumer questions in a Reddit AMA (Ask Me Something) thread and in a submit on X this afternoon, Altman admitted to a variety of points which have disrupted the launch of GPT-5, together with defective mannequin switching, poor efficiency, and consumer confusion — prompting OpenAI to partially stroll again a few of its platform modifications and reinstate consumer entry to earlier fashions like GPT-4o.
“It was a little bit extra bumpy than we hoped for,” Altman wrote in reply to a query on Reddit relating to the massive GPT-5 launch.
As for inaccurate mannequin efficiency charts proven off throughout OpenAI’s GPT-5 livestream, Altman mentioned: “Individuals had been working late and had been very drained, and human error received in the way in which. So much comes collectively for a livestream within the final hours.”

Whereas he famous the accompanying weblog submit and system card had been correct, the missteps additional muddied a launch already going through scrutiny from early customers and builders.
Issues with new automated mannequin router
One key cause for the difficulty in accordance with Altman stems from OpenAI’s new automated “router” that assigns consumer prompts to one in all 4 GPT-5 variants — common, mini, nano, and professional — with an non-compulsory “pondering” mode for heavier reasoning duties.
On X, Altman revealed {that a} key a part of that system — the autoswitcher — was “out of fee for a bit of the day,” inflicting GPT-5 to seem “method dumber” than meant.
In response, OpenAI says it’s implementing modifications to the mannequin choice boundary and can make it extra clear which mannequin is responding to a given question.
A UI replace can also be on the way in which to assist customers manually set off pondering mode.
Moreover, Altman confirmed that OpenAI will now permit ChatGPT Plus customers to proceed utilizing GPT-4o — the prior default mannequin — after a wave of complaints about GPT-5’s inconsistent efficiency. He mentioned on Reddit the corporate is “making an attempt to assemble extra information on the tradeoffs” earlier than deciding how lengthy to supply legacy fashions.
But many customers together with OpenAI beta testers like Wharton College of Enterprise professor Ethan Mollick expressed confused and dismay at OpenAI unilaterally upgrading their ChatGPT experiences to GPT-5 and initially taking away entry to the older fashions.
Actual-world efficiency lags behind hype
OpenAI’s inner benchmarks could present GPT-5 main the pack of LLMs, however real-world customers are sharing a unique expertise.
Because the launch, customers have posted quite a few examples of GPT-5 making fundamental errors in math, logic, and coding duties.
Information scientist Colin Fraser posted screenshots of GPT-5 incorrectly fixing whether or not 8.888 repeating equals 9 (it doesn’t, clearly), whereas one other consumer confirmed it flubbing a easy algebra drawback: 5.9 = x + 5.11.
And nonetheless different customers reported bother getting correct solutions to math phrase issues or utilizing GPT-5 to debug its personal presentation charts.
Developer suggestions hasn’t been a lot better, with customers posting photos of GPT faring worse at “one-shot” sure programming duties — finishing them nicely with a single-prompt — in comparison with rival AI lab Anthropic’s new mannequin Claude Opus 4.1.
And safety agency SPLX discovered GPT-5 nonetheless suffers from severe vulnerabilities to immediate injection and obfuscated logic assaults until its security layer is hardened.
OpenAI within the highlight
With 700 million weekly customers on ChatGPT, OpenAI stays the most important participant in generative AI by viewers.
However that scale has introduced rising pains. Altman famous in his X submit that API visitors doubled over 24 hours following the GPT-5 launch, contributing to platform instability.
In response, OpenAI says it is going to double charge limits for ChatGPT Plus customers, and proceed to tweak infrastructure because it gathers suggestions.
However the early missteps — compounded by complicated UX modifications and errors in a high-profile launch — have opened a window for rivals to achieve floor.
The strain is on for OpenAI to show that GPT-5 isn’t simply an incremental replace, however a real step ahead. Based mostly on the preliminary rollout, many customers aren’t satisfied — but.
