An expected strategic shift in the generative AI landscape
Officially announced for summer 2025, ChatGPT-5 crystallizes the expectations of professional users and the general public alike. After the significant advances of GPT-4.5 and the introduction of specialized agents such as Deep Research and Codex, this new version promises an even more fluid, multimodal and contextual experience. What will this mean for users in concrete terms, and how can we prepare for it now?
ChatGPT-5: towards multimodal, proactive and personalized conversational AI
According to initial information unveiled by OpenAI at the DevDay 2025 conference, ChatGPT-5 will introduce several major innovations:
- Extended contextual understanding: long-term memory is now activated by default, enabling in-depth personalization of interactions.
- Receiving and processing complex instructions: the ability to interpret instructions in several stages will be improved, facilitating the automation of business workflows.
- Advanced multimodality: ChatGPT-5 will simultaneously understand and generate text, image, audio and code, with improved intermodal consistency.
- Enhanced interoperability: the model will be able to connect to third-party applications via the new “intelligent connectors” introduced with GPT-4.5.
These enhancements are designed to transform ChatGPT into a true productivity assistant integrated into the work environment, capable of meeting complex needs in a variety of business contexts.
New functions expected for summer 2025
The ChatGPT-5 version, which will initially be rolled out to paying subscribers (ChatGPT Plus and Enterprise), will feature :
- A multilingual collaborative mode, capable of generating cross-referenced summaries or multilingual summaries in real time;
- An enhanced visual interface for code editing, graphical generation and document analysis;
- Priority access to customizable agents, configurable by sector or function;
- Native integration with Office 365, Google Workspace and Notion, facilitating document and reporting uses.
Comparison of the main changes: ChatGPT-4.5 vs ChatGPT-5
| Functionality | ChatGPT-4.5 | ChatGPT-5 (summer 2025) |
| Memory | Experimental, disabled by default | Activated by default, long term memory and customizable |
| Multimodality | Text + image (partial) | Text, image, audio, code, with improved intermodal consistency |
| Specialized agents | Agents available, not customizable | Configurable agents for specific business uses |
| Integration with third-party tools | Manual integrations (APIs, plugins) | Smart connectors with apps (Office 365, Notion, Slack…) |
| Reasoning skills | Structured logical reasoning, limited to defined tasks | Interpretation of complex instructions and extended reasoning chains |
| User interface | Rich text chat, plugins | Interactive visual interface, collaborative options |
| Transparency / auditability | Poor traceability of responses | Automatic justification system and interaction logs |
| Availability | Free version + Plus + Enterprise | First Enterprise (July), then Plus (August), partial freemium by the end of 2025 |
| Contextual personalization | Little developed, contextual in the session | Persistent user profile, customizable response style |
| API usage | Classic API GPT-4 turbo | Enhanced PLC with sector-specific fine-tuning |
Anticipated use cases in professional environments
Initial demonstrations suggest a wide range of concrete applications:
- Human resources: automated creation of multilingual job descriptions, in-context CV evaluation.
- Finance: generation of cross-sector reports, modeling of economic scenarios.
- Education: design of multimodal interactive teaching aids.
- Healthcare: multilingual medical record synthesis with visualization support.
- Marketing: automated multi-channel campaigns, real-time semantic analysis.
According to a recent IDC study, 64% of companies surveyed said they wanted to integrate ChatGPT-5 into their processes as soon as it was launched.1.
Towards a more responsible and governable AI
OpenAI emphasizes the ethical safeguards built into ChatGPT-5 :
- Transparency of reasoning: an automatic annotation system makes it possible to trace the sources and stages of algorithmic reasoning;
- Context-sensitive security filters: adjustable by sector (legal, medical, education) to prevent risky responses;
- Auditability of exchanges: each request can be saved and verified in a secure session log.
These elements meet the requirements of the future European AI regulation (AI Act) and the growing demands for compliance in regulated sectors2.
A deployment strategy to watch
ChatGPT-5 will be deployed in several waves:
- July 2025: early access for ChatGPT Enterprise users.
- August 2025: available to Plus users.
- End 2025: partial opening of functions to the general public, in freemium mode.
OpenAI also includes an enhanced API for developers, with fine-tuning options for specific fields of activity (energy, education, law…).
ChatGPT-5: a new era for digital assistants?
More than just an update, ChatGPT-5 represents a technological convergence between conversational agent, search engine, graphical assistant and business copilot. This version could redefine the boundaries between work tool and intelligent companion, accelerating the spread of AI into all sectors of society.
