OpenAI is expanding the reach of its AI research assistant with a brand-new, lightweight version of the ChatGPT Deep Research tool. Designed to be faster, cheaper, and more accessible, this version is now available for ChatGPT Plus, Team, and Pro users, and it’s also starting to roll out to free users.
Here’s everything you need to know about this new release and what it means for users looking to simplify their research using artificial intelligence.
What Is ChatGPT Deep Research?
Before diving into the update, let’s take a moment to understand what Deep Research in ChatGPT is all about.
OpenAI’s Deep Research feature helps users automatically generate detailed research summaries by browsing the web, analyzing content, and compiling accurate information on a given topic. This tool has proven useful for professionals, students, and curious minds who need quick, reliable, and in-depth answers without manually going through dozens of articles or sources.
Now Comes a Lightweight Version
To further enhance user access and reduce the strain on computing resources, OpenAI has created a “lightweight” version of its Deep Research tool. This version offers most of the functionality of the full tool but in a more compact, efficient, and cost-friendly package.
According to OpenAI, this new tool still delivers quality results, though the responses might be a bit shorter and more concise compared to the original full-featured version.
Why a Lightweight Version Was Needed
The demand for AI-powered research has skyrocketed, especially with increased competition from tools like Google Gemini, Microsoft Copilot, and xAI’s Grok. All of these platforms offer some form of deep reasoning and self-verifying capabilities, helping users perform advanced research tasks.
OpenAI needed a solution that would scale better for wider usage, including free and lower-tier paid users. The full version of Deep Research consumes more resources, so usage had to be limited. With the lightweight model, OpenAI can offer more queries to more people without compromising on speed or user experience.
Powered by OpenAI’s o4-Mini Model
The lightweight Deep Research tool is powered by a scaled-down version of OpenAI’s latest AI model, known as o4-mini. While not as advanced as the flagship model behind full Deep Research, o4-mini is still smart and capable, built to deliver useful, factual summaries from web content.
OpenAI confirmed that although it’s a lighter model, o4-mini retains a high level of reasoning and intelligence, allowing the lightweight tool to produce shorter but still insightful answers.
How It Works for Users
One of the most impressive features of this release is how seamlessly the lightweight tool integrates into ChatGPT’s interface.
If a user reaches the usage limit for the full Deep Research tool, ChatGPT automatically switches to the lightweight version. There’s no interruption or confusing prompts — the system just continues delivering research responses using the o4-mini engine instead.
This automation makes the experience smoother and ensures that users still get access to powerful AI insights without worrying about which version they’re using.
Availability Across Plans
OpenAI is rolling out the lightweight Deep Research tool across its different subscription levels. Here’s how it breaks down:
🔹 Free Users
For the first time, free users can now access Deep Research features. However, they are limited to 5 research tasks per month.
🔹 ChatGPT Plus and Team Users
Subscribers on Plus and Team plans can enjoy 25 monthly research tasks, which include both full and lightweight versions. Once their full Deep Research quota is used up, the lightweight version takes over automatically.
🔹 ChatGPT Pro Users
Those on the Pro plan have access to a generous 250 research tasks per month, allowing heavy users, researchers, and professionals to get the most out of the platform.
🔹 Enterprise and Education Users
OpenAI announced that educational and enterprise users will also receive access starting next week. They will get the same usage levels as Team users, encouraging widespread adoption across schools, universities, and businesses.
What’s Different in the Lightweight Version?
While the core idea remains the same — compiling and delivering smart research from across the web — the lightweight version has a few differences worth noting:
- Shorter Answers: Responses are a bit more to-the-point, but still rich in information.
- Faster Performance: Because it uses fewer resources, the lightweight tool responds more quickly.
- Cheaper to Operate: The o4-mini model is more efficient, which allows OpenAI to offer more queries to users.
- Automatic Switching: When full research queries run out, ChatGPT switches users to the lightweight tool without interruption.
Why This Matters for the Future of AI Research
This update shows how OpenAI is evolving to meet growing user demand and make research tools more accessible and inclusive. By offering a lighter version of an already powerful tool, OpenAI is opening the door for students, small businesses, and everyday users to access smart AI research without needing a premium subscription.
It’s also a direct response to the competition heating up in the AI space. With more companies entering the scene, OpenAI’s focus on efficiency, affordability, and usability helps keep ChatGPT a leader in the AI assistant market.
The Bigger Picture: AI and Research Tools
The idea of using AI to perform research is growing rapidly. Whether it’s summarizing academic papers, collecting news from across the web, or comparing product reviews — people want fast, trustworthy summaries without digging through endless sources.
OpenAI, Google, Microsoft, and others are building tools that not only find information but can reason through it, cross-check facts, and present findings in human-like language.
The lightweight Deep Research tool fits perfectly into this trend, offering users the power of reasoning AI at their fingertips — even if they’re using the free version of ChatGPT.
