The User Backlash: A Tide of Disappointment on Social Media

However, beyond the carefully curated press releases and expert endorsements, a different narrative was unfolding. On platforms like Reddit and X (formerly Twitter), a wave of discontent began to swell among everyday users of AI chatbots. The sentiment was perhaps best encapsulated in a Reddit thread titled, simply, 'GPT-5 is horrible.'

• Cold and Robotic Responses: Many users complained that GPT-5 felt less conversational and more robotic than its predecessors. One user lamented, "It feels like they’ve lobotomized it. All the personality is gone, replaced by this corporate drone that gives bland, generic answers." The warmth and human-like qualities that made earlier models appealing seemed to have been sacrificed in the pursuit of accuracy and efficiency.

• Performance Issues: Others pointed to inconsistent performance, with some users reporting that GPT-5 struggled with tasks that Claude, an AI assistant known for its sophisticated reasoning and creative capabilities, handled with ease. There were grumblings about logical fallacies, a surprising inability to understand complex instructions, and a general sense that the model was somehow less intelligent than expected.

• Speed Concerns: Perhaps the most consistent complaint revolved around speed. While experts celebrated improvements in processing time, many users found GPT-5 noticeably slower, especially when using function calling. "It takes forever to get a response when I'm using function calls," one user wrote. "I'm spending more time waiting than actually working."

The dichotomy between expert praise and user disappointment highlights the complex challenges inherent in developing and deploying AI models. While companies and researchers may focus on benchmarks and technical specifications, the ultimate test lies in the user experience. As we delve deeper into GPT-5's capabilities and limitations, we must consider not only what it can do but also how it feels to use.

GPT-5 Performance Deep Dive: Coding Prowess, Hallucination Reduction, and Writing Style

GPT-5 promises a lot on paper, but how does it actually perform when put to the test? Let's dive into its coding capabilities, improvements in hallucination reduction, and the evolving nuances of its writing style.

Coding Capabilities: A Mixed Bag

While GPT-5 boasts impressive benchmark scores in coding, its real-world application seems to present a more nuanced picture. It has shown strong performance across several coding benchmarks, including:

• SWE-bench Verified: A standard benchmark for evaluating coding proficiency.

• Aider polyglot: Demonstrating its ability to handle multiple programming languages.

• Qodo AI PR Benchmark: A specialized benchmark for assessing performance in pull request scenarios. The Qodo AI team themselves have reported positive findings on this particular benchmark, suggesting that GPT-5 excels at understanding and generating code for pull requests.

However, the experiences of developers who've used it in their daily work are more varied. Some have reported that GPT-5 is capable of providing one-shot solutions to complex coding problems, generating functional code snippets with minimal prompting. Others have found it to be less reliable, with the model sometimes getting lost in the details or producing verbose outputs that require significant refinement. It's like having a brilliant but somewhat unfocused coding partner – capable of genius, but needing careful guidance. This is where tools like GitHub Copilot, an AI pair programmer that offers real-time code suggestions and helps automate repetitive tasks, can really shine by filling in those gaps.

While GPT-5 shows coding promise on benchmarks, practical application reveals a more complex reality.

Hallucination Reduction: Progress, but Still Present

OpenAI has made bold claims about reducing hallucinations in GPT-5, stating a 45% reduction in factual errors compared to GPT-4o when using web search. They also claim an 80% reduction in errors compared to o3 in "thinking mode." These numbers sound impressive, but what do they mean in the real world?

While these figures suggest a significant improvement, it's important to consider real-world hallucination rates and seek community validation. Early adopters of GPT-5 have reported a noticeable decrease in blatant factual errors. However, more subtle forms of misinformation still exist, requiring users to remain vigilant and double-check information, potentially using tools like Perplexity, which focuses on providing accurate answers with proper source citations.

Beth Barnes from METR has publicly identified instances where GPT-5 still makes factual mistakes, reminding us that even with improvements, AI models aren't infallible. It’s like a GPS that's been updated, but still occasionally directs you down a one-way street – proceed with caution!

Writing and Communication Style: The Personality Problem

One of the most prevalent concerns surrounding GPT-5 is its writing and communication style. User feedback consistently points to a perceived loss of personality and an increase in formulaic writing. It's as if the model is trying too hard to be neutral and objective, resulting in bland and uninspired text.

GPT-5's writing, while technically proficient, often lacks the spark and creativity of its predecessors.

Some users have also reported that GPT-5 provides short, insufficient replies and engages in what they describe as

Enterprise Success vs. Consumer Frustration: A Tale of Two GPT-5 Experiences

It seems that OpenAI's latest offering, GPT-5, is creating a bifurcated reality, where enterprise clients are singing its praises, while everyday users are left scratching their heads in frustration.

The Enterprise Edge: A Smooth Transition

For larger businesses and development tool companies, the move to GPT-5 appears to be a resounding success. Many are reporting significant improvements in efficiency, accuracy, and overall performance. Take Amgen, for example, who lauded GPT-5's improved ability to navigate ambiguous requests. This is especially valuable for tasks that require a nuanced understanding of context and complex problem-solving.

"GPT-5's capacity to handle ambiguity has been a game-changer for us," says a senior data scientist at Amgen. "It's reduced the need for constant fine-tuning and allows us to focus on more strategic initiatives."

This sentiment is echoed across various sectors, suggesting that GPT-5's advancements are particularly well-suited for complex, enterprise-level applications. Tools such as Salesforce Platform, a leading cloud-based CRM, are leveraging the power of the model for enhanced automation and customer service capabilities.

The Consumer Conundrum: Disappointment and Regression

On the flip side, the experience for individual users, especially those on free tiers or even Plus subscriptions, has been less than stellar. Many are reporting a noticeable decline in the quality of responses, an increase in irrelevant or nonsensical outputs, and a general sense that GPT-5 feels like a step backward.

One of the most significant grievances is the limited functionality afforded to Plus subscribers. While they are paying for premium access, they often find themselves restricted from utilizing the advanced reasoning models that are supposedly the hallmark of GPT-5. This restricted access creates a sense of being shortchanged, as users feel they are not getting the full value of their subscription.

• Restricted Access: Limited access to advanced reasoning models.

• Inconsistent Performance: Outputs often feel less coherent and reliable.

• Frustration: A general sense of disappointment and regression compared to older models.

Adding insult to injury, many users are lamenting the loss of access to older, more reliable models like GPT-3.5. These models, while not as cutting-edge, were often preferred for their consistency and predictability. The forced upgrade to GPT-5, even with its supposed improvements, has left some users feeling like they've lost a valuable tool.

The Reasoning Riddle: A Matter of Explicit Prompting

A recurring theme in user complaints revolves around the dynamic routing system that GPT-5 employs. While the intention might be to optimize performance and tailor responses, the result is often inconsistent reasoning. The model seems to struggle to grasp the underlying intent of a query without explicit prompting, leading to frustrating and time-consuming interactions.

For instance, a user might ask a simple question requiring a logical deduction, only to receive a vague or irrelevant answer. Only by explicitly guiding the model through each step of the reasoning process can a satisfactory response be obtained. This need for constant hand-holding defeats the purpose of having an advanced AI model in the first place.

The Price of Progress: API Access and Token Costs

Another point of contention is the accessibility and pricing of the GPT-5 API. With a price tag of $1.25 per million input tokens, it's becoming increasingly expensive for developers and smaller businesses to leverage the model's capabilities. This high cost barrier effectively limits access to GPT-5 for a significant portion of the user base.

In conclusion, the rollout of GPT-5 paints a complex picture. While enterprise clients are reaping the benefits of its advanced capabilities, individual users are grappling with limited functionality, inconsistent performance, and high costs. The key takeaway is that OpenAI needs to address the concerns of its consumer base to ensure that GPT-5 becomes a truly accessible and valuable tool for everyone, not just a select few. This divergence in user experience raises crucial questions about the direction of AI development and the importance of catering to diverse user needs, which we'll explore further in the next section examining ethical considerations.
