OpenAI makes Deep Research available to free users with a new lightweight version
Last week, OpenAI announced a major update to its Deep Research feature, which until now had been reserved for subscribers. The company is now rolling out a lightweight version of this tool that will also be available to users of the free version of ChatGPT.
What is the new lightweight version of Deep Research?
The new lightweight version of the Deep Research tool is powered by the o4-mini model, which is a smaller variant of the model used in the full version. This version was designed to offer a similar quality and depth of analysis as the original tool, but with shorter responses, enabling more efficient use of computing resources. "The lightweight version of Deep Research provides equally high-quality results, just in a more compact form," said an OpenAI representative in a press release. "This solution allows us to make advanced analysis available to more users while maintaining reasonable operating costs."
Availability for different types of users
The implementation of this feature is being rolled out gradually:
- Free users will gain access to 5 queries per month.
- ChatGPT Plus, Team and Pro subscribers will receive additional queries beyond their original limits.
- Enterprise and educational users will gain access over the course of next week.
This strategy reflects OpenAI's effort to democratize access to advanced AI tools while preserving a pricing advantage for paying users.
The importance of making it available
The launch of a lightweight version of Deep Research for free users represents an interesting shift in OpenAI's strategy. The company has long balanced making its most advanced features available to a broader audience with the need to fund development through premium subscriptions. "We see this as an investment in expanding AI literacy," OpenAI explains. "The more people have access to in-depth analysis tools, the better equipped they will be to distinguish between high-quality and low-quality information in the age of AI."
Technical details
The o4-mini model that powers the lightweight version is optimized to provide concise but information-rich responses. Compared with the full-scale model, it uses fewer parameters, resulting in lower computational demands and making it possible to serve more users simultaneously. OpenAI also emphasizes that the new version has been carefully fine-tuned to provide reliable citations and links, which is a key feature for a tool focused on research.
Future development
The company has indicated that this is part of a broader strategy to make advanced AI tools more accessible. In the coming months, we can expect further similar initiatives that will balance performance, accessibility and economic sustainability. For users interested in trying out this feature, the lightweight version of Deep Research will be available directly in the ChatGPT interface without the need for additional setup.
