A detailed introduction to the latest features of ChatGPT-5.

ChatGPT-5





🤖 A comprehensive analysis of GPT-5's latest features

My current system is based on the GPT-5 architecture . Compared with the previous GPT-4/GPT-4 Turbo, there are several obvious upgrade directions:


1. More accurate language understanding and generation

  • Improved ability to understand long texts
    • GPT-5 can process longer inputs (hundreds of thousands of words) at a time and analyze long documents, contracts, and research reports without interruption.
  • Contextual memory is more stable
    • You can better remember the details discussed previously during the conversation, and it is not easy to forget the key points in long-term conversations.
  • Multilingual performance is more natural
    • The recognition rate for mixed Chinese and English input (commonly used by Hong Kong people) is higher, and the generated tone is closer to local usage.

2. Multimodal Capabilities

  • Text + Image Processing
    • In addition to text, GPT-5 can directly understand the content of images (for example, analyzing a car photo, reading screenshot text, and helping you interpret charts).
  • Combined generation capabilities
    • You can generate image sketches based on text descriptions (the corresponding module must be enabled).
  • Support for more sensory data in the future
    • OpenAI is testing its ability to process audio and video, such as listening to recordings and directly sorting out the key points.

3. Reasoning and logic upgrade

  • Stronger logical chain
    • It performs more stably in scenarios requiring rigorous logic, such as mathematical calculations, legal interpretation, and program debugging, reducing occasional random reasoning by GPT-4.
  • Transparency of multi-step reasoning (Chain of Thought)
    • GPT-5 can be asked to demonstrate its thinking process to facilitate verification of logical correctness.

4. Personalization and persistent memory

  • Long-term memory (in long-term beta testing)
    • It can remember user long-term preferences, such as writing style, common formats, and topics of interest.
  • Customize your character
    • Users can set GPT-5's tone, identity, and knowledge scope, such as "Hong Kong editor", "professional lawyer", and "data analyst".


5. Tool and plug-in integration

  • Built-in Code Interpreter (advanced data analysis)
    • It can directly process Excel, CSV, JSON and other data to generate charts and statistical analysis.
  • Browsing
    • With browsing permissions enabled, you can search for the latest online information in real time (depending on the functionality of the application platform).
  • Third-party plugin support
    • For example, flight query, map navigation, stock data, etc., real-time connection to external API.

6. More flexible output format

  • Complex structure output
    • It can directly generate multiple formats such as JSON, HTML, Markdown, LaTeX, etc., which is convenient for developers and content creators.
  • Multiple versions of replies
    • You can provide several answers from different styles or angles at once to facilitate comparison.
  • Controllable tone and length
    • More precise control over reply word count, formality, sense of humor, etc.

7. Performance and cost optimization

  • Improved computing efficiency
    • The response speed is faster than GPT-4, especially for long text generation.
  • Smarter resource scheduling
    • For simple questions, it answers quickly with less computing resources; for complex tasks, it automatically calls high-precision mode.

📌 Editor's actual test experience

After using it for a while, I feel that the biggest advantages of GPT-5 are:

  1. More in tune with local context : The words used to describe Hong Kong place names, transportation, and culture are more natural.
  2. Stable processing of long documents : tens of thousands of words of information can be analyzed at once without interruption.
  3. Reasoning is more reliable : Data analysis and interpretation of legal texts are less error-prone than before.
  4. Multimodal practicality : Image understanding is particularly helpful for data organization and business analysis.

🔮 Possible future updates

  • A more complete long-term memory system (remembers your conversation history over the years)
  • Instant voice conversation function (low latency)
  • More accurate video and multimedia analysis
  • A more open plugin ecosystem (connecting to more local services)

📊 GPT Series Feature Upgrade Comparison Table

Functional scope GPT-3.5 GPT-4 / GPT-4 Turbo GPT-5 (latest)
Language understanding accuracy Generally, conversations flow smoothly, but long texts tend to lose focus. Better understanding of complex sentences and support for more languages Long articles have more stable logic and high recognition of mixed Chinese and English texts (suitable for Hong Kong use)
Contextual Memory Can memorize thousands of words Memory range expanded, but long conversations are still forgotten Can handle conversations of hundreds of thousands of words, with stable memory of details
Multimodal capabilities Only supports text Text + image input (analyze images) Text + image input is more accurate, and audio and video will be tested in the future
reasoning ability Simple logical reasoning Improved complex reasoning skills, but with occasional errors Multi-step reasoning is more reliable and can demonstrate the thinking process
Personalization function No persistent memory You can set the tone and role, but in the short term Test long-term memory, which can remember user preferences and historical conversations
Tool Integration No built-in plugins Support Code Interpreter and web browsing (some platforms) Smoother tool integration and support for more third-party APIs
Output format Text-based Markdown, simple JSON Highly structured output (JSON, HTML, LaTeX, etc.)
Spawn Speed Faster, but slower for complex tasks Turbo version is faster The speed of long article generation is improved, and resource scheduling is more intelligent
Localized performance Neutral Standard Chinese Can use traditional Chinese, the spoken language is average Supports Hong Kong local terms and cultural background to be more relevant
Applicable Scenarios Basic conversation and simple writing Professional copywriting, programming, and academic assistance Professional research, business analysis, multimedia processing

🌟 Editor's summary

  • GPT-3.5 : Suitable for general conversations and entry-level writing. It has fast speed but limited depth of understanding.
  • GPT-4 : Greatly improves professionalism and is suitable for high-precision needs in business, law, programming, etc.
  • GPT-5 : An all-round upgrade, especially in long-text processing, localization, multimodality, and reasoning capabilities , making it particularly friendly to Hong Kong users.

Editor's Quote : If GPT-3.5 is a "friend who knows how to talk", GPT-4 is a "consultant with professional knowledge", and GPT-5 is already a "personal assistant who knows multiple skills and remembers your preferences".
