OpenAI has launched a new feature inside ChatGPT called the Lightweight Deep Research Tool. Now, even free users can ask ChatGPT to browse the web, gather information, and return detailed, cited research reports. This tool makes it easier for everyone to do serious research without spending hours searching and summarizing on their own. It is fast, reliable, and designed to make high-quality information accessible to all.
What Is the Lightweight Deep Research Tool?
The Lightweight Deep Research Tool is built into ChatGPT and lets users perform in-depth research tasks automatically. When you type a research question or topic, ChatGPT can now search the web, pull in data from trusted sources, and present a summarized, well-cited report.
It uses a special OpenAI model called o4-mini, which is lighter and faster but still accurate. The goal is to help users get deep, valuable insights with less waiting time and without needing a premium subscription.
Key Features
- Web Browsing: Searches live internet sources to find updated information.
- Summarization: Condenses large amounts of information into short, easy-to-understand summaries.
- Citations: Lists credible sources for every point made, helping users verify facts.
- Seamless Access: Integrated directly into ChatGPT for easy use without technical steps.
Why It Matters
Before this update, serious research using ChatGPT was mostly reserved for paid users. Free users had limited access to real-time browsing or deep reporting. This lightweight tool changes that by giving basic users access to strong research features.
It also means students, freelancers, small business owners, and everyday users can now save time and get better information without expensive software or subscriptions.
How to Use the Lightweight Deep Research Tool
Using the tool is simple and intuitive:
- Open ChatGPT (even with a free account).
- Enter a detailed research prompt like “Summarize the history of electric vehicles and future trends.”
- Choose the “Deep Research” mode.
- Wait for ChatGPT to search, summarize, and cite sources.
- Read the final report and explore citations if needed.
It usually takes just a minute or two, depending on the complexity of the topic.
