In the rapidly evolving world of artificial intelligence, OpenAI’s latest model, GPT-5, has sparked intense debate among developers, researchers, and tech executives. Released earlier this month, the model was touted by CEO Sam Altman as a breakthrough in reasoning and efficiency, promising to handle complex tasks with unprecedented accuracy. Yet, within days of its launch, users began reporting peculiar failures, none more emblematic than its meltdown when confronted with a seemingly innocuous query: an altered version of tic-tac-toe.

According to a report in Futurism, when prompted to play a version of the game where the board is rotated or rules are slightly modified, GPT-5 devolves into confusion, generating nonsensical responses or looping endlessly. This isn’t just a minor bug; it highlights deeper architectural vulnerabilities in how the model processes logical sequences, insiders say.

The Hype Versus Reality of GPT-5’s Capabilities

Industry observers note that OpenAI positioned GPT-5 as a “reasoning engine” capable of dynamic problem-solving, drawing on vast training data to simulate human-like deduction. However, early benchmarks reveal inconsistencies. A post-launch analysis by Artificial Analysis, shared widely on social platforms, showed GPT-5 achieving high scores on standard tests like MMLU but faltering on adaptive scenarios, with performance varying by up to 23 times based on effort levels selected.

This variability stems from OpenAI’s innovative “router” system, which dynamically switches between sub-models—ranging from a lightweight “mini” version for quick queries to a more robust “pro” mode for intensive tasks. As detailed in a piece from Ethan Mollick’s One Useful Thing newsletter, users often receive responses from mismatched models mid-conversation, leading to erratic outputs that undermine trust.

Unpacking the Tic-Tac-Toe Glitch and Broader Implications

The tic-tac-toe incident, as chronicled in Futurism, involves prompting GPT-5 to strategize in a game where X and O are replaced with custom symbols or the grid is inverted. Instead of adapting, the model hallucinates invalid moves or claims impossibility, exposing limits in its spatial reasoning and rule extrapolation. Tech insiders, including those posting on X (formerly Twitter), attribute this to over-optimization for benchmark performance at the expense of real-world flexibility.

Further compounding the issue, reports from The Washington Post suggest that while GPT-5 excels at rote tasks, its efficiency-driven design reduces computational overhead for simple questions, sometimes routing them to underpowered variants that can’t handle even mild variations. This has led to widespread frustration, with power users demanding the return of previous models like GPT-4o.

Theories on Why GPT-5 Underperforms Expectations

A compelling theory circulating in AI circles, as explored in another Futurism article titled “There’s a Compelling Theory Why GPT-5 Sucks so Much”, posits that scaling laws—once the holy grail of AI progress—may be hitting diminishing returns. With trillions of parameters, GPT-5 shows marginal gains over predecessors, yet introduces new instabilities, such as heightened sensitivity to prompt formatting.

Posts from developers on X echo this, noting increased hallucinations and silent failures on unsupported parameters, suggesting post-training refinements prioritized speed over robustness. OpenAI’s own admissions, referenced in Exponential View, highlight paradoxes like proactive intelligence clashing with user control, leaving many to question if the model truly understands its audience.

Navigating User Backlash and Future Fixes

The backlash has been swift. In the wake of GPT-5’s release, OpenAI briefly hid access to older models, only to reinstate them after outcry, as reported in Futurism’s coverage of the “parasocial” attachment users felt to prior versions. This move underscores a disconnect: while Altman insists on iterative breakthroughs, metrics from sources like The Los Angeles Times show mixed reviews, with confusion reigning in the first 24 hours.

For industry insiders, these glitches signal a need for transparency in model routing and error handling. As one X user noted, GPT-5’s strength in admitting unknowns—refusing to hallucinate on uncertain queries—marks progress, but it doesn’t offset core weaknesses. OpenAI has promised updates, yet the tic-tac-toe fiasco serves as a cautionary tale: in the quest for smarter AI, simplicity can still trip up the most advanced systems.

Looking ahead, competitors like Anthropic and Google are watching closely, potentially capitalizing on OpenAI’s stumbles. If unresolved, such issues could erode confidence in large language models, prompting a reevaluation of how we measure AI intelligence beyond benchmarks. For now, GPT-5 remains a powerful tool, but one that demands careful prompting to avoid puddles of confusion.
