GPT-5 Faces Early Scrutiny: Performance Concerns and OpenAI‘s Response
The highly anticipated launch of GPT-5 hasn’t been without its bumps. Initial reports suggest the new model from OpenAI is struggling with basic reasoning and accuracy in several key areas, raising questions about whether it represents a significant leap forward. Let’s break down the issues and what OpenAI is doing to address them.Early Performance Issues Surface
Several users quickly identified shortcomings in GPT-5’s capabilities shortly after its release. Colin Fraser shared screenshots demonstrating the model incorrectly determining the equivalence of 8.888 repeating and 9 – a fundamental mathematical concept. Furthermore, others reported errors in simple algebra, like solving the equation 5.9 = x + 5.11. These aren’t isolated incidents. Users have also encountered difficulties with accurate answers to math word problems and debugging presentation charts generated by the AI. The concerns extend beyond basic math.Developers have noted that GPT-5 appears to perform worse than Anthropic’s claude Opus 4.1 on “one-shot” programming tasks – completing tasks effectively with a single prompt. This is a critical area where OpenAI has historically led. Security vulnerabilities also remain a concern. A recent analysis by SPLX revealed that GPT-5 is still susceptible to prompt injection and obfuscated logic attacks unless its safety layers are significantly strengthened.OpenAI Navigates Launch Challenges
OpenAI currently boasts a massive user base, with ChatGPT reaching 700 million weekly users. However, this scale has presented challenges during the GPT-5 rollout.CEO Sam Altman acknowledged a doubling of API traffic within 24 hours of the launch, contributing to platform instability.In response, OpenAI is taking steps to improve the situation. They plan to double rate limits for ChatGPT Plus users and continue refining the underlying infrastructure based on user feedback. These early missteps, combined with confusing user experience changes and launch errors, have created an opportunity for competitors to gain traction. The pressure is now on openai to demonstrate that GPT-5 is more than just an incremental upgrade.What This means for You

OpenAI needs to prove GPT-5 delivers on its promise of ”reasoning superpowers.” For now, many users remain skeptical, and the company faces a critical period to address these concerns and solidify its position as a leader in generative AI.OpenAI co-founder and CEO Sam Altman is publicly acknowledging major hiccups in yesterday’s rollout of GPT-5, the company’s new, flagship large language model (LLM) — advertised as its most powerful and capable yet.
Answering user questions in a Reddit AMA (Ask Me anything) thread and in a post on X this afternoon, Altman admitted to a range of issues that have disrupted the launch of GPT-5, including faulty model switching, poor performance, and user confusion — prompting OpenAI to partially walk back some of its platform changes and reinstate user access to earlier models like GPT-4o.
“It was a little more bumpy than we hoped for,” Altman wrote in reply to a question on Reddit regarding the big GPT-5 launch.
As for erroneous model performance charts shown off during OpenAI’s GPT-5 livestream, Altman said: “People were working late and were very tired, and human error got in the way. A lot comes together for a livestream in the last hours.”

The current situation presents a chance for other AI labs to gain ground.Anthropic’s Claude Opus 4.1,in particular,is being positioned as a strong choice,especially for tasks requiring precise reasoning and coding ability. The pressure is now on OpenAI to demonstrate that GPT-5 is more than just an incremental update. Many users remain unconvinced, and the company needs to deliver on its promises of “reasoning superpowers” to maintain its leadership position. Here’s a quick recap of the key concerns: Mathematical errors: GPT-5 struggles with basic arithmetic and algebra. Coding Performance: It lags behind competitors like Claude Opus 4.1 in coding tasks. Security Risks: Vulnerabilities to prompt injection and obfuscated attacks persist. Platform Stability: High demand caused initial instability and required rate limiting.* User Experience: confusing changes have added to user frustration. Ultimately, the success of GPT-5 will depend on OpenAI’s ability to address these issues quickly and effectively. You can expect continued scrutiny and comparison with rival models as the AI landscape evolves.while he noted the accompanying blog post and system card were accurate, the missteps further muddied a launch already facing scrutiny from early users and developers.
Problems with new automatic model router
One key reason for the trouble according to Altman stems from OpenAI’s new automatic “router” that assigns user prompts to one of four GPT-5 variants — regular, mini, nano, and pro — with an optional “thinking” mode for heavier reasoning tasks.
On X, altman revealed that a key part of that system — the autoswitcher — was “out of commission for a chunk of the day,” causing GPT-5 to appear “way dumber” than intended.
in response, OpenAI says it’s implementing changes to the model decision boundary and will make it more transparent which model is responding to a given query.
A UI update is also on the way to help users manually trigger thinking mode.
Additionally, Altman confirmed that OpenAI will now allow ChatGPT Plus users to continue using GPT-4o — the prior default model — after a wave of complaints about GPT-5’s inconsistent performance. He said on Reddit the company is “trying to gather more data on the tradeoffs” before deciding how long to offer legacy models.
Yet many users including OpenAI beta testers like Wharton School of Business professor Ethan Mollick expressed confused and dismay at OpenAI unilaterally upgrading their ChatGPT experiences to GPT-5 and initially taking away access to the older models.
Real-world performance lags behind hype
OpenAI’s internal benchmarks may show GPT-5 leading the pack of LLMs, but real-world users are sharing a different experience.
Sence the launch, users have posted numerous examples of GPT-5 making basic errors in math, logic, and coding tasks.
Data scientist Colin Fraser posted screenshots of GPT-5 incorrectly solving whether 8.888 repeating equals 9 (it does not, obviously), while another user showed it flubbing a simple algebra problem: 5.9 = x + 5.11.
And still other users reported trouble getting accurate answers to math word problems or using GPT-5 to debug its own presentation charts.
Developer feedback hasn’t been much better, with users posting images of GPT faring worse at “one-shot” certain programming tasks — completing them well with a single-prompt — compared to rival AI lab Anthropic’s new model Claude Opus 4.1.
And security firm SPLX found GPT-5 still suffers from serious vulnerabilities to prompt injection and obfuscated logic attacks unless its safety layer is hardened.
OpenAI in the spotlight
With 700 million weekly users on ChatGPT, OpenAI remains the largest player in generative AI by audience.
But that scale has brought growing pains.Altman noted in his X post that API traffic doubled over 24 hours following the GPT-5 launch, contributing to platform instability.
In response, openai says it will double rate limits for ChatGPT Plus users, and continue to tweak infrastructure as it gathers feedback.
But the early missteps — compounded by confusing UX changes and errors in a high-profile launch — have opened a window for rivals to gain ground.
The pressure is on for OpenAI to prove that GPT-5 isn’t just an incremental update, but a true step forward. Based on the initial rollout, many users aren’t convinced — yet.
