OpenAI’s highly anticipated GPT-5 has encountered a rough debut as users reported that it felt surprisingly less capable than its predecessor, GPT-4o.
The culprit? A malfunctioning real-time router that failed to select the most appropriate model for user queries.
In response, Sam Altman acknowledged the issue and assured users that GPT-5 would ‘seem smarter starting today’.
To ease the transition, OpenAI is restoring access to GPT-4o for Plus subscribers and doubling rate limits to encourage experimentation and feedback gathering.
Beyond technical fixes, the incident has sparked broader debate within the AI community about balancing innovation with emotional resonance. Some users lament GPT-5’s colder tone and tighter alignment, even as developers strive for safer, more responsible AI behaviour.

After Elon Musk accused Apple of favouring OpenAI’s ChatGPT over other AI applications on the App Store, there was a strong response from OpenAI CEO Sam Altman.
Altman alleged that Musk manipulates the social media platform X for his benefit, targeting competitors and critics. The exchange adds to their history of public disagreements since Musk left OpenAI’s board in 2018.
Musk’s claim centres on Apple’s refusal to list X or Grok (XAI’s AI app) in the App Store’s ‘Must have’ section, despite X being the top news app worldwide and Grok ranking fifth.
Although Musk has not provided evidence for antitrust violations, a recent US court ruling found Apple in contempt for restricting App Store competition. The EU also fined Apple €500 million earlier this year over commercial restrictions on app developers.
OpenAI’s ChatGPT currently leads the App Store’s ‘Top Free Apps’ list for iPhones in the US, while Grok holds the fifth spot. Musk’s accusations highlight ongoing tensions in the AI industry as big tech companies battle for app visibility and market dominance.
The situation emphasises how regulatory scrutiny and legal challenges shape competition within the digital economy.

OpenAI has released reasoning-focused open-weight models in a strategic response to China’s surging AI ecosystem, led by DeepSeek’s disruptive efficiency. Unlike earlier coverage, the shift is framed not merely as competitive posturing but as a deeper recognition of shifting innovation philosophies.
DeepSeek’s rise stems from maximizing limited resources under the US’s export restrictions, proving that top-tier AI doesn’t require massive chip clusters. The agility has emboldened the open-source AI sector in China, where over 10 labs now rival those in the US, fundamentally reshaping competitive dynamics.
OpenAI’s ‘gpt-oss’ models, which reveal numerical parameters for customization, mark a departure from its traditional closed approach. Industry watchers see this as a hybrid play, retaining proprietary strengths while embracing openness to appeal to global developers.
The implications stretch beyond technology into geopolitics. US export controls may have inadvertently fueled Chinese AI innovation, with DeepSeek’s self-reliant architecture now serving as a proof point for resilience. DeepSeek’s achievement challenges the US’s historically resource-intensive approach to AI.
AI rivalry may spur collaboration or escalate competition. DeepSeek advances models like DeepSeek-MoE, while OpenAI strikes a balance between openness and monetization. Global AI dynamics shift, raising both technological and philosophical stakes.

OpenAI chief executive Sam Altman has warned that many ChatGPT users are engaging with AI in self-destructive ways. His comments follow backlash over the sudden discontinuation of GPT-4o and other older models, which he admitted was a mistake.
Altman said that users form powerful attachments to specific AI models, and while most can distinguish between reality and fiction, a small minority cannot. He stressed OpenAI’s responsibility to manage the risks for those in mentally fragile states.
Using ChatGPT as a therapist or life coach was not his concern, as many people already benefit from it. Instead, he worried about cases where advice subtly undermines a user’s long-term well-being.
The model removals triggered a huge social-media outcry, with complaints that newer versions offered shorter, less emotionally rich responses. OpenAI has since restored GPT-4o for Plus subscribers, while free users will only have access to GPT-5.

OpenAI will make its GPT-4o model available again for ChatGPT Plus subscribers after replacing it with GPT-5, following complaints from users who said the change was abrupt and unwelcome.
Chief executive Sam Altman confirmed that subscribers can choose between the two models, adding that the company will monitor usage before deciding how long to keep older versions available.
The decision comes days after the debut of GPT-5, which was introduced without the option to select previous models manually.
Some users said they valued the continuity and emotional connection they had formed with GPT-4o, describing it as unique and meaningful instead of simply replaceable. Others preferred having the freedom to select a model manually rather than relying on a default.
Altman acknowledged that GPT-5’s performance appeared weaker at times, attributing it partly to a temporary malfunction in the automatic switching system.
He also said adjustments are being made to improve how the system selects the most suitable model in different scenarios.

OpenAI’s new GPT‑5 model has been unveiled, and the company offers it free to all users. Three model versions, gpt‑5, gpt‑5‑mini and gpt‑5‑nano, offer developers a balance of performance, cost and latency.
CEO Sam Altman applauded India’s rapid AI adoption and hinted that India, currently OpenAI’s second‑largest market, may soon become the largest. A visit to India is planned for September.
The new GPT‑5 achieves a level of expertise akin to a PhD‑level professional and is described as a meaningful step towards AGI. OpenAI intends to make the model notably accessible through its free tier.
Head of ChatGPT Nick Turley noted that GPT‑5 significantly enhances understanding across more than twelve Indian languages, reinforcing India as a key market for localisation.

OpenAI has launched GPT-5, replacing previous ChatGPT models and removing the model picker option. CEO Sam Altman called it a PhD-level AI, claiming improvements in reasoning, writing, coding, accuracy, and health-related queries, with fewer hallucinations. The rollout followed right after the announcement.
GPT-5 includes both an efficient and a reasoning model, but users no longer choose which to engage, OpenAI’s system automatically routes queries. The change has frustrated many, as favourite models like GPT-4o and o3 are no longer available.
Users on social media and forums complain that GPT-5 gives shorter, less engaging answers and has less personality. Some say the model ignores instructions, gets basic things wrong, and is slower despite not running in ‘thinking mode’.
Several users allege OpenAI shortened responses deliberately to reduce costs, removing emotional intelligence to discourage casual chatting. Critics believe the move could result in lost subscriptions despite efficiency gains.
Others describe GPT-5 as more organised but clipped in tone, with no clear quality improvement over earlier models. The loss of previous models has left some feeling that the upgrade is a downgrade, with one user saying it feels like ‘watching a close friend die’.

OpenAI has unveiled GPT-5, the latest generation of its widely used ChatGPT tool, offering what CEO Sam Altman described as a ‘huge improvement’ in capability.
Now free to all users, the model builds on previous versions but stops short of the human-like reasoning associated with accurate artificial general intelligence.
Altman compared the leap in performance to ‘talking to a PhD-level expert’ instead of a student.
While GPT-5 does not learn continuously from new experiences, it is designed to excel in coding, writing, healthcare and other specialist areas.
Industry observers say the release underscores the rapid acceleration in AI, with rivals such as Google, Meta, Microsoft, Amazon, and Elon Musk’s xAI investing heavily in the race. Chinese startup DeepSeek has also drawn attention for producing powerful models using less costly chips.
OpenAI has emphasised GPT-5’s safety features, with its research team training the system to avoid deception and prevent harmful outputs.
Alongside the flagship release, the company launched two open-weight models that can be freely downloaded and modified, a move seen as both a nod to its nonprofit origins and a challenge to competitors’ open-source offerings.

Endex.ai has secured $14 million in funding to bring AI directly into Microsoft Excel. The funding round was led by the OpenAI Startup Fund, marking a significant moment for traditional tools in the business world.
Founded in 2022 by Tarun Amasa and Kevin Yang, the startup has spent the past year collaborating quietly with financial institutions to refine its product.
Now available to the public through limited invites, the tool embeds itself within Excel and helps users manage tasks like financial modelling, data cleanup, and detailed analysis (without switching applications).
Unlike broader AI tools, Endex has been designed specifically for finance professionals. It understands financial terminology, adapts to user habits, and references trusted data sources such as SEC filings, CapIQ, and earnings reports.
The company describes its product as Excel-native, aiming to enhance rather than replace a tool already deeply integrated into finance work.
With the new funding, Endex plans to expand development and scale its reach. The AI agent already works on both Mac and Windows, and its frictionless interface is proving attractive in a field where saving time and improving accuracy can make a substantial difference.
