On August 8, 2025, OpenAI officially released the new generation large model—GPT-5. Following a highly anticipated launch event, GPT-5 is now available to all ChatGPT users immediately, regardless of whether they are free or paid users, who can directly experience this latest achievement in AI.

GPT-5: Transforming into an All-Purpose Digital Assistant with Comprehensive Upgrades

Compared to previous versions, GPT-5 not only makes significant leaps in fundamental capabilities but also becomes more practical and efficient. It can do more than just hold conversations, write summaries, and handle daily information; it can truly understand your complex needs and complete continuous tasks. From requirement analysis, content generation, web development, and code debugging to finally deploying a product, GPT-5 is a genuinely "capable" AI, even able to autonomously think about the next step and remember your context without needing to repeat everything constantly.

Extended Context for Complete Understanding of Text

One of GPT-5's biggest breakthroughs is that its context window has expanded to 400K tokens. Now, whether you throw a novel of hundreds of thousands of words, a week's worth of scheduling records, or meeting minutes lasting several hours at it, it can remember, understand, and distill the key points completely, helping you continue advancing the same project or conversation without missing key information.

Persistent Memory and Adaptive Thinking

GPT-5 not only extends its context but also thinks flexibly according to the complexity of tasks. For simple questions, it responds quickly and concisely; for complex tasks, it automatically engages in deep reasoning, generating detailed and well-structured answers. You can also use the "thinking" feature to see how GPT-5 deduces and makes decisions, making it easier to review and reuse.

Fewer Hallucinations, Enhanced Safety and Accuracy

Internally at OpenAI, GPT-5 has reduced its factual error rate by 45% compared to its predecessor, answering questions more accurately in specialized fields such as healthcare, law, and science. In response to users' concerns about "hallucinations" and the safety of sensitive situations, GPT-5 introduces the Safe Completion mechanism, which no longer just denies user requests but gently guides, explains the reasons, and offers acceptable alternatives, facilitating risk management and compliance.

Demonstration of Actual Capabilities: Code, Documentation, Health, Task Automation

The practicality of GPT-5 is most directly reflected in various real scenarios. This is not just an evolution of large models in the lab but an AI tool implemented in everyone's daily work and life. Here are real experiences from the launch event and initial users:

1. Programming Helper, Automatic Development and Debugging

GPT-5 possesses complete multilingual programming capabilities; it can not only write code snippets but also analyze and understand decision logic. For instance:

Automatically Generate Complete Websites: Just describe your idea in Chinese, and GPT-5 can create a French learning website complete with interactivity, cards, progress tracking, and even mini-games in just a few minutes, taking visual style and UI into account, and automatically adapting to light and dark themes.
Understanding and Fixing Complex Codebases: GPT-5 can analyze large codebases in minutes, detect bug causes, and automatically fix them. Even when handling millions of lines of code, it can quickly locate, modify, and test, greatly improving efficiency.
Multistep Code Task Management: Users can see the AI's "thinking chain" in real-time, understanding each step (like reading, modifying, rolling back, and re-testing), with the debugging process being fully transparent.

python

Example: Let GPT-5 automatically fix a bug in a Python project

Simply upload the project and error logs, and input a description

prompt = """ Help me locate and fix the MIME type error in the upload_pdf() method of the GitHub repository openai/openai-python, and explain the reason for the fix. """

GPT-5 will automatically output the analysis process, modification suggestions, and a complete usable code

2. More Natural Writing, Suitable for Multiple Scenarios

Whether it's news articles, popular science, jokes, Xiaohongshu-style writing, or professional reports and educational materials, the text generated by GPT-5 is more refined, natural, and structured. It can assist users in:

Creating storyboard scripts, writing screenplays, simulating dialogues
Rapidly drafting reports, summarizing meeting points, and rewriting content
Automatically extracting key information from materials and optimizing expressions

3. Office and Automation: Freeing Up Daily Repetitive Tasks

GPT-5 can handle document tasks such as data organization, automatic Excel generation, building visual charts, and structuring process plans all in one go. Just drag and drop the document materials or raw tables, and the rest will be taken care of automatically.

Automatically generating project PPT outlines, landing page structures, and conversion suggestions
Completing daily reports, weekly reports, project proposals, and other documents in seconds
Understanding and analyzing Gmail and calendars, automatically scheduling your appointments

4. Health Literacy and Professional Scenarios

The launch event demonstrated GPT-5's applications in the health sector. Users can upload photos of hospital reports, and within seconds GPT-5 can translate complex medical reports into easily understandable language, helping analyze treatment plans and prepare questions while explaining the pros and cons of each medical decision and reassuring emotions. While the official recommendation is not to replace doctors, this makes professional knowledge more accessible to everyone.

Multiple Versions with Low Barriers to Entry, Free Users Can Use Directly

GPT-5 adopts a tiered model strategy this time:

GPT-5 / GPT-5-mini: For all free and Plus users, responding smoothly to everyday tasks. Free users can submit 10 requests every 5 hours, while Plus and Pro versions have higher limits.
GPT-5 Pro: For complex engineering and high reasoning demands, offering the highest accuracy and depth of reasoning. Available for Pro users.
GPT-5 nano: Extremely concise, suitable for API scenarios, with ultra-low latency and low-cost batch processing.

Every request is automatically matched to the best model by the system, eliminating the need for manual switching; ordinary Q&A uses mini, while high-difficulty tasks automatically switch to Pro.

For developers, OpenAI's official website has launched API documentation related to GPT-5, supporting text, chat, tool calls, structured outputs, and custom reasoning parameters. For example:

import openai

openai.ChatCompletion.create(
    model="gpt-5-pro",
    messages=[{"role": "user", "content": "Help me write a Python script for data analysis"}],
    reasoning_effort="high", # Automatically enable deep reasoning
    verbosity="high"         # Responses include detailed comments and documentation
)

New Voice Styles and Multimodal Capabilities

Beyond text, GPT-5's voice interactions are also more natural. It supports various voice presets—rational, calm, listening, nerdy—with styles of your choice, and can adapt speech rate and emotional tone. Whether learning a language, simulating training, or practicing spoken language, it provides significant assistance.

The ability to understand images and long documents across modalities has also improved significantly, automatically recognizing image content, document layout, and structure for one-stop material analysis.

Comprehensive Access for Enterprises and Education, Flexible Implementation Scenarios
