GPT-5: The Ultimate AI Model Has Arrived!
After numerous "pushbacks" and "sneak peeks," the long-awaited GPT-5 has finally been released.
On August 8, Beijing time, OpenAI held a live online launch event that lasted over an hour, officially unveiling GPT-5. Unlike previous model updates, which were brief and mainly presented by the research team, GPT-5's release was more elaborate, with OpenAI CEO Sam Altman making a special appearance at the event.
According to a Securities Times reporter's summary, the key highlights of the event were:
Integrated model: GPT-5 is an integrated model that combines large language models (GPT series) and reasoning models (o series), which means users no longer need to manually switch between different models.
Performance boost: According to OpenAI's publicly disclosed test data, GPT-5 has demonstrated top-notch performance in mathematics, programming, visual perception, and health domains, surpassing previous generations by a significant margin.
Error reduction: Compared with GPT-4o, GPT-5 has reduced its factual error rate by 45% (in deep thinking mode, the error rate is even lower by 80%). This has made it more accurate and reliable.
"Expert-level" AI model
During the launch event, Altman praised GPT-5 as a "giant leap" compared to all previous models. He also said that if GPT-4 was like a college student, then GPT-5 is like a true expert.
The most striking feature of GPT-5 is its integration with the GPT series (large language models) and o series (reasoning models), allowing it to schedule sub-models. Altman tweeted about this, emphasizing that "GPT-5 is an integrated model, which means no more switching between different models – it will decide when to go deeper."
According to the introduction, GPT-5 uses a nested three-tier integrated architecture for the first time. The system consists of three parts: GPT-5-main (for processing regular questions), GPT-5-thinking (for deep thinking), and a real-time decision-making mechanism.
In terms of performance, GPT-5 has demonstrated impressive results in various domains. For example, in the 2025 AIME test, GPT-5 reached 94.6% accuracy without tool assistance, surpassing o3 and other previous models.
It's worth noting that GPT-5 has taken the top spot on the Large Model Arena leaderboard with its exceptional performance in various tasks.
In terms of application scenarios, GPT-5 has demonstrated remarkable coding capabilities, allowing it to create a game called "Jumping Ball Runner" within a few sentences. The game features colorful graphics, cartoon-style characters, and high-score records.
As a long-awaited product, GPT-5 has finally arrived. However, in the past year or so, there have been numerous "pushbacks" and "sneak peeks," leaving users eagerly anticipating its release.
Reduced AI hallucinations
GPT-5 has demonstrated industry-leading performance in reducing AI hallucinations. Compared with GPT-4o, GPT-5's factual error rate is reduced by 45% (in deep thinking mode, the error rate is even lower by 80%).
It's worth noting that OpenAI has been working on a capital operation plan to sell shares to employees and former employees. According to a report on August 6, OpenAI has begun negotiations with potential buyers at an estimated value of around $500 billion.
