What does GPT-4o represent?

OpenAI's flagship model, GPT-4o, also known as ChatGPT-4o, is a multimodal tool that can handle text, images, and audio instantly. Unlike previous versions that were limited to word processing, it offers seamless interaction, similar to natural dialogue.

Origin and evolution of GPT-4o in 2025

Launched in May 2024, GPT-4o quickly gained attention due to its speed and versatility. Following public debate surrounding the launch of GPT-5 in August 2025, OpenAI opted to return to GPT-4o as the default option for paid subscribers. This move is a response to users' preference for GPT-4o as a more intuitive "virtual friend."

In April 2025, GPT-4 gave way to GPT-4o, marking a transition to more efficient and sustainable models. In France, with a user community estimated at between 16 and 20 million, its evolution increasingly integrates local languages and areas such as image analysis in ophthalmology.

Significant differences compared to previous versions.

Compared to GPT-4, GPT-4o is twice as fast and supports a context of 128 tokens. Unlike GPT-000, which is limited to text, it excels in the area of multimodality. In 3.5, updates will improve its visualization capabilities, making it more efficient for practical tasks.

Key Features of ChatGPT-4o

GPT-4o stands out for its ability to combine text, images, and audio, making interactions more immersive. By 2025, thanks to its improvements, it will become an essential tool for productivity.

Multimodal Capabilities: Text, Image and Voice

This model analyzes images to diagnose problems, such as in ophthalmology, and responds vocally in real time (232 ms latency). For example, send a photo of an eye for a quick assessment—ideal for French professionals. It also generates personalized audio content.

Performance and optimizations in 2025

With a reduced fee ($2,50 per million input tokens), GPT-4o is more energy-efficient and compliant with EU sustainability standards. Updates in March 2025 would refine its coding and design fluidity.

Integration with Web Search and API

Integrate it into apps via API for web searches in French. By 2025, this will facilitate integrations in tourism or healthcare, with contextualized responses.

GPT-4o Evaluation: Tests and Performance in France

As an expert, I have reviewed research showing that GPT-4o performs well in real-world situations, especially in France where language assessments are essential.

Tests in the French Medical and Educational Field

In the French national ophthalmology exam, GPT-4o achieved 67,5% accuracy on MCQs, surpassing GPT-4 but falling short of human residents. In education, 80% of French students use it for clear explanations, boosting productivity.

Real Advantages and Limitations

Benefits: Multimodal accuracy and personalization. Limitations: Possibility of illusions on complex themes, and inability to produce videos. The 2025 updates mitigate these vulnerabilities.
