OpenAI launches GPT-5, claims ‘PhD-level’ expertise

ISLAMABAD: OpenAI has launched its most advanced AI model to date, GPT-5, calling it “smarter, faster, and more useful” than its predecessors, with capabilities reportedly reaching PhD-level expertise across multiple domains.

Unveiled by CEO Sam Altman ahead of its Thursday release, GPT-5 is being positioned as a unified AI system that combines fast responses for everyday queries with deep reasoning for complex problems.

It automatically chooses which mode to operate in – standard or “GPT-5 thinking” – based on the user’s prompt and task complexity.

We're introducing GPT-5. The evals are SOTA, but the real story is usefulness. It helps with what people care about– shipping code, creative writing, and navigating health info– with more steadiness and less friction. We also cut hallucinations. It's better calibrated, says "I… https://t.co/btFL29BgqT

This is the kind of intelligence that would have been unimaginable just a few years ago, Altman remarked, calling GPT-5 a new chapter in the evolution of artificial intelligence.

GPT-5 shines in writing, health, coding

OpenAI says the model offers major upgrades in real-world performance, significantly reducing hallucinations, improving instruction-following, and resisting sycophantic replies.

GPT-5 particularly shines in writing, health, and coding – a space where it now rivals professional developers in generating and debugging complex applications and websites.

Plus users get enhanced access to GPT-5, while Pro subscribers can use GPT-5 Pro, a version with deeper reasoning capabilities.

A scaled-down version handles overflow when usage caps are met, with plans to merge all versions into a single, seamless experience in the future.

The launch further intensifies the AI race among tech giants, as firms like Google, Meta, and Anthropic push their own advanced models.

GPT-5’s arrival also follows OpenAI’s increasing efforts to position ChatGPT as a serious tool for professionals, especially in healthcare and software development.
