ChatGPT 5: What the new GPT model can do

With the introduction of ChatGPT 5 OpenAI is bringing the next major language model to the market. Expectations were high — and were even exceeded in many areas. GPT-5 is not just a development, but a significant technological leap.

Thanks to better memory, deeper context understanding, and multimodal capabilities, ChatGPT 5 opens up new opportunities for companies, developers, and end users. In this article, we show what GPT-5 Specifically, how it differs from its predecessor and for which areas of application the new model is particularly suitable.

‍

What is ChatGPT 5? — Overview of the new language model

ChatGPT 5 is based on the latest OpenAI GPT-5 model and represents the most powerful version of AI-based language processing to date.

Compared to GPT-4o, the new model offers a variety of improvements:

• Better long-term memory and contextual understanding
• Multimodal capabilities (text, image, audio, video)
• Personalized use through customizable profiles
• Stronger API connectivity and workflow automation
• Improved security for data processing and data protection

GPT-5 is designed for demanding applications — and focuses on productivity, quality, and flexibility.

One system — three modes: This is how the new GPT-5 thinking model works

With ChatGPT 5, OpenAI has introduced a uniform system with three intelligent work modes for the first time: The standard mode (Chat) provides quick, direct answers for simple tasks such as emails, social media posts, or text corrections. The mode Thinking analyses much more deeply and is suitable for strategic, creative or data-based projects. Thinking Pro is only available to paid pro, team and enterprise users and offers maximum precision for critical applications — such as in research, law or regulated industries.

An integrated AI router automatically selects the appropriate mode, but can be manually adjusted at any time via the model menu. Particularly practical: While longer thought processes are running, the button can be used “Get a quick answer” Request a short version at any time — ideal when efficiency comes before depth.

The most important new features of ChatGPT 5 at a glance

What exactly does GPT-5 better than previous models? Here is an overview of the most important functions:

• 1. Improved context processing:
  GPT-5 can process significantly larger amounts of text and remember and correctly classify previous conversations over longer periods of time.
• 2. Real long-term memory:
  User profiles, preferences, common tasks, and work contexts are saved permanently — and ensure more consistent results.
• 3. Multimodal interaction:
  ChatGPT 5 not only understands and generates text, but also Image, audio, and video content — depending on the application and configuration.
• 4. Personalized behavior:
  Through “personas” or “custom instructions,” GPT-5 can act as a specific role — such as a project manager, content strategist, or data analyst.
• 5. Faster and more efficient:
  The response speed was noticeably improved, as was the quality of complex answers with technical or analytical depth.
• 6. API extensions for companies:
  Companies can integrate GPT-5 directly into their systems, including fine-tuned functions and AI agents.

GPT-5 vs. GPT-4o: Key Differences

Even though GPT-4o (the previous top model) is already very powerful, GPT-5 It has some clear advantages:

• GPT-4o has limited memory — GPT-5 can retain information across many interactions
• GPT-5 enables deeper personalization through continuous learning
• With GPT-5, multimodality is more stable and better integrated
• Data processing is more secure and transparent
• GPT-5 reacts faster and in a more structured way to complex requests

Overall, GPT-5 is much more “human” in its interaction — without losing efficiency.

‍

For which areas of application is ChatGPT 5 particularly suitable?

Thanks to its advanced capabilities, GPT-5 particularly suitable for demanding, professional scenarios. Here are a few typical fields of application:

• Knowledge management:
  GPT-5 can understand, summarize, and strategically classify internal documents — e.g. for onboarding, training, or internal communication.
• Consulting & analysis:
  Data-driven analyses, market comparisons or SWOT evaluations are carried out more thoroughly and quickly.
• Content creation:
  Whether it's white papers, campaign texts or social media strategies — GPT-5 delivers high-quality, tailor-made content.
• Customer Support:
  GPT-5 can act as an intelligent support agent that understands complex requests and responds contextually.
• Research & Development:
  GPT-5 provides support in researching, comparing studies and simulating scenarios — even with subject-specific vocabulary.

‍

Multimodality in GPT-5: text, image, audio and more

One of the most notable new features is improved multimodality. GPT-5 can not only process text, but also with:

• pictures (e.g. analyze charts, describe screenshots)
• audio (understand or generate spoken language yourself)
• video (context-based feedback or summaries)
  interact.

This feature makes GPT-5 particularly valuable in areas such as:

• Video content production
• barrier-free communication
• E-learning and interactive training
• UX analyses (e.g. visual feedback from apps)

‍

Personalization with GPT-5: AI adapts to you

Another key feature is the continuous personalization. GPT-5 remembers:

• Language preferences
• typical work processes
• tools and APIs used
• preferred response formats

This means: The more you use GPT-5, the The result will be more individual. Team profiles or company-wide settings can also be defined — ideal for use in companies.

‍

Security and privacy with ChatGPT 5

As the range of functions grows, so do data protection and security requirements. OpenAI has implemented the following improvements in GPT-5:

• Fine-grained rights management for API usage
• Delete function for stored data and conversations
• Transparent storage processes and retention policies
• Opt-in for memory function (Memory can be deactivated)
• GDPR compliance when used in the EU (depending on the provider)

The new model thus provides a solid basis for safety-critical industries such as finance, law, or healthcare.

GPT-5 limitations: What is not (yet) perfect

Despite all progress, GPT-5 still has certain limitations:

• costs: GPT-5 can only be used (as of today) in higher-priced plans or via API
• Complexity: It can be more complex to set up and personalize
• Learning curve: New users must first become familiar with extended functions
• Regulatory issues: Depending on the sector, additional tests are required

If you want to use GPT-5, you shouldn't start blindly — but plan strategically.

‍

Accessing ChatGPT 5: Who can use it?

GPT-5 can currently be used in the following ways:

• ChatGPT Pro Plan at OpenAI
• Team and enterprise plans for companies
• API access via OpenAI or Microsoft Azure
• No free use available (as of September 2025)

For companies, it is recommended to use the ChatGPT Team Plan or the direct integration via API, e.g. for internal applications.

‍

Conclusion: GPT-5 sets new standards for AI applications

With GPT-5, OpenAI raises the potential uses of AI to a new level. The model is more powerful, context-sensitive and versatile than all predecessors — and makes it possible to truly establish AI as an assistant in everyday work.

It is particularly exciting to use AI in companies not only to experiment, but also as strategic tool want to use.
