AIBase News, August 8, 2025, OpenAI officially released its highly anticipated next-generation artificial intelligence model, GPT-5. This is the most significant model upgrade since the release of GPT-4, marking another important milestone in the development of AI technology.

Technological Breakthroughs: Comprehensive Upgrade of Unified Model Architecture

GPT-5 integrates multiple previous technological breakthroughs from OpenAI into a unified system, including the multimodal capabilities of GPT-4o, the reasoning functions of the o series, and advanced mathematical processing capabilities. Unlike previous approaches that required switching between different models for different tasks, GPT-5 uses an intelligent routing system that automatically selects the most suitable processing method based on the type of conversation, complexity, and tool requirements.

In core performance metrics, GPT-5 shows significant improvements: mathematical ability reaches 94.6% (AIME2025 benchmark test), programming ability reaches 74.9% in real codebase tests (SWE-bench Verified), and multimodal understanding capability is 84.2% (MMMU benchmark test).

User Experience: Full Access, Tiered Services

OpenAI has adopted an unprecedented open strategy, making GPT-5 available to all ChatGPT users, including free users, Plus, Pro, and Team users. This is the first time free users have access to a reasoning model.

The specific user permissions are as follows:

Free Users: Can directly use the basic version of GPT-5, experiencing for the first time a reasoning model with "thinking" capabilities

Plus Users: In addition to the basic version, they can also use the "GPT-5 Thinking" version, enjoying stronger reasoning capabilities

Pro Users: Have unlimited access to GPT-5 and GPT-5 Pro, and can switch to older versions of models as needed

Enterprise and Educational Users: Will gain access next week and will also receive the GPT-5 Pro version, providing more reliable and detailed extended reasoning capabilities

Technological Innovation: Dramatic Reduction in "Hallucination" Issues

In reducing AI "hallucinations" (generation of false information), GPT-5 has made significant breakthroughs. In anonymized ChatGPT production environment testing, the probability of GPT-5's answers containing factual errors is reduced by about 45% compared to GPT-4o, and when using the reasoning function, the error rate is reduced by about 80% compared to the o3 model.

Additionally, GPT-5 has shown significant improvements in efficiency. In tasks such as visual reasoning, code writing, and solving graduate-level scientific problems, its performance exceeds the o3 model, but the number of output tokens is reduced by 50-80%.

Practical Applications: Redefining Human-Computer Interaction

In the launch demonstration, OpenAI showcased GPT-5's "vibe coding" capability, where users only need to provide simple text descriptions to quickly generate complete web applications. For example, when asked to create an application to help English speakers learn French, GPT-5 generated a complete application with flashcards, quizzes, and progress tracking features within seconds.

In terms of user experience design, GPT-5 has also seen significant improvements. Compared to GPT-4o, the new model reduces overly flattering expressions and uses fewer unnecessary emojis. It is more subtle and considerate in subsequent conversations, making users feel like "not talking to an AI, but rather having a chat with a friend with a doctorate-level intelligence."

Business Impact: Driving a New Wave of Enterprise AI Adoption

As of now, 5 million paid users are using ChatGPT's commercial products. Organizations such as BNY Mellon, California State University, Figma, Intercom, Lowe's, Morgan Stanley, SoftBank, and T-Mobile have integrated AI tools into their employees' workflows.

The release of GPT-5 is expected to further accelerate enterprise adoption of AI technology, particularly in decision-making, collaboration improvement, and rapid execution of high-risk tasks.

Release Background: Intensifying Industry Competition

Amid intensifying competition in the AI industry, especially with the U.S. government stating it will "do whatever it takes" to beat China in the AI field, the release of GPT-5 is particularly significant. This release also fulfills OpenAI CEO Sam Altman's promise made in February 2025 to "release GPT-5 within a few months."

It is reported that GPT-5 was trained on Microsoft Azure AI supercomputers, representing the highest level of current AI infrastructure.

Industry Outlook

GPT-5 has become the new default model for ChatGPT, replacing previous models such as GPT-4o, o3, o4-mini, GPT-4.1, and GPT-4.5. Users simply need to open ChatGPT and input their questions, and GPT-5 will automatically handle the rest, applying reasoning functions when necessary.

With the full deployment of GPT-5, the application of AI technology in daily work and life is expected to enter a new stage of development. This is not just a technological upgrade, but may also redefine the way people interact with AI, bringing new possibilities to various industries.
