Deep Research

Deep Research – OpenAI's next-generation advanced search tool (2025)

Deep Research, or "In-Depth Research" in French, is a major advancement in the field of artificial intelligence conversational agents. Unlike traditional online searches, which are often limited to providing a list of links, this technology is capable of exploring a question in depth, cross-referencing information from multiple reliable sources, and then analyzing it with discernment. The result: clear, structured reports supported by precise references, enriched with relevant recommendations. It is a tool designed not only to find answers, but also to put them into perspective and offer a comprehensive and reasoned vision of a subject.

1. Deep Research: a documentary revolution by OpenAI

Deep Research is more than just an extension of ChatGPT — it's a standalone assistant capable of:

• Browse and analyze websites, PDFs, images, tables, etc.

• Cross-reference and synthesize data while systematically citing sources.

• Generate structured reports, enriched with visualizations in the latest updates.

Powered by an optimized version of the model o3, designed for complex reasoning, Deep Research stands out as a digital substitute for the approach of a human analyst, reducing the workload to a few dozen minutes.

2. Deployment and Access — Month by Month

• February 2025 : Launching for Pro users in the UK, Switzerland, and the EEA.

• February 25, 2025 : open to all paying subscribers (Plus, Team, Enterprise, Edu), according to separate quotas.

• April 2025 : quota extension — Plus/Team/Enterprise: 25 requests/month (half of which in the “light” version via o4-mini); Pro: 250 requests (50% light); Free: 5 “light” requests.

• June–July 2025 : improved interface with interactive process visualization, integration of graphs directly into reports.

3. Use cases — The daily lives of professionals transformed

Ideal for knowledge-intensive industries—finance, science, regulatory, political, engineering, or even sophisticated purchasing decision support—Deep Research outperforms traditional searches with its ability to navigate complex topics—such as market trends, medical protocols, or detailed product comparisons.

A specialist journal praised its ability to transform a complex query into a structured document in a simple access, citing the benchmark Humanity's Last Exam, where Deep Research displays a record score of 26,6%, well above GPT-4o (3,3%) or DeepSeek R1 (9,4%).

4. Instructions — From query to detailed report

• Open ChatGPT, enable Deep Search in settings.

• Enter a clear and targeted query, e.g.: “Study of batteries for electric vehicles: innovations, costs, user feedback”.

• (Optional) Add documents—PDFs, images, tables—to enrich the context.

• Initiate the request: the agent works for 5 to 30 minutes, notifying you upon completion.

• A full report is displayed in the conversation, with quotes, summary, and graphs.

5. Why give him your trust?

Deep Research takes longer, but produces solid, reliable reports that can be used as professional documentation.

6. Known limitations to keep in mind

• Results depend on query quality: imprecise wording can hamper analysis.

• The system may occasionally improve erroneous or unverified information: vigilance is still required.

• Restricted use, even for Pro subscribers: any excess automatically switches to the less powerful “light” version.

In short, Deep Research embodies the next generation of information assistant: autonomous, rigorous, capable of competing with a professional in terms of information synthesis. In 2025, it redefines what we can expect from AI in academic, technical, or decision-making research—as long as we remain critical and demanding.

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 ChatGPT Online
