What if AI transformed hours of research into minutes? Deep Research, OpenAI's new weapon for 2025, pushes the limits of ChatGPT with accurate, sourced reports. In this article, discover this revolutionary tool and uncover the secrets of this innovation for both the curious and experts.
What is Deep Research?
Launched in February 2025 by OpenAI, Deep Research is an innovative feature integrated into ChatGPT. This artificial intelligence agent doesn't just respond quickly: it's designed to conduct in-depth web research. By exploring hundreds of sources, it analyzes data and produces detailed reports in minutes—a task that would take a human hours. Based on an advanced version of the model o3, Deep Research positions itself as a powerful tool against competitors like Perplexity or Google solutions.
How does Deep Research work?
Deep Research follows a structured and autonomous process. When a complex query is submitted, it:
- Planned : Breaks the question down into clear steps.
- Collection : Browse websites, articles, PDFs or other accessible content.
- Analysis : Filters and synthesizes information using tools like Python.
- Write : Provides a structured report with precise quotes, sometimes enriched with graphics.
This process, which takes between 5 and 30 minutes depending on the complexity, offers transparent and well-sourced results.
How to use Deep Research?
To access this feature, you need a ChatGPT subscription:
- Go to the interface of Chat GPT.
- Enable the “Deep Research” option.
- Enter a detailed query (e.g., “What are the technology trends for 2025?”).
- Add documents (PDFs, images) if necessary to clarify the context.
ChatGPT Plus subscribers ($20/month) are allowed 10 monthly searches, while Pro users ($200/month) are allowed 120 queries.
Deep Research's strengths
- Multi-step search : It explores a subject from different angles.
- Transparency : Each information is accompanied by a verifiable source.
- versatility : It processes texts, images or digital data and can generate visualizations.
- Adaptability : Useful for academic, professional or personal needs.
What types of research are most appropriate?
Deep Research excels in areas requiring in-depth analysis:
- Finance : Study of markets or company performance.
- Science : Literature synthesis with quotations.
- Technology : Comparison of innovations.
- Consumption : Research for complex purchasing decisions.
In what areas does Deep Research stand out?
Compared to other tools, such as Perplexity or Gemini, Deep Research shines with:
- Its accuracy: 26,6% on the Humanity's Last Exam test, far ahead of its rivals.
- His ability to reason and contextualize.
- Its rigor thanks to the sources cited.
How does it improve accuracy?
Thanks to its advanced model and continuous learning, Deep Research adjusts its results in real time, prioritizing reliable data. However, it can sometimes produce errors or misinterpret ambiguous information, requiring verification.
Free or paid: what’s the difference?
Deep Research is not available in the free version of ChatGPT. Only paid subscribers have access to it, with limitations depending on their plan:
- Chat GPT Plus : 10 searches/month, for occasional use.
- ChatGPT Pro : 120 searches/month, for intensive needs.
OpenAI reserves this exclusivity for subscribers to offset the high computational costs, but a more accessible version is planned for the future. You can also join Chatbot completely free and unlimited on chatgptfrancais.org
OpenAI's Deep Research vs. Perplexity
- Perplexity : Free (5 searches/day), fast, but less detailed (21,1% on Humanity's Last Exam).
- OpenAI : Paid, slower, but more precise and exhaustive, ideal for complex projects.
Conclusion
OpenAI's Deep Research redefines online research by combining speed, thoroughness, and transparency. Whether you're in France or elsewhere, this tool is aimed at researchers, professionals, or the curious who want reliable answers without spending hours. Compared to its competitors, it stands out for its depth, despite limited access to paid subscribers. A must-have for anyone looking to go beyond simple, superficial research.
