OpenAI has extended its 'deep research' tool to ChatGPT Plus subscribers as of February 25, 2025, following its initial release to Pro users on February 2, 2025. This expansion broadens access to an AI-powered feature designed to autonomously analyze and synthesize large volumes of data, raising questions about its implications for research-intensive fields.

Origins and Functionality of Deep Research
Introduced earlier this month, deep research is an AI tool developed by OpenAI to assist with complex information-gathering tasks. Built on a tailored version of the o3 model, optimized for web browsing and Python-based data processing, it can search the internet, review documents such as PDFs and images, and produce structured reports with cited sources. The tool aims to replicate aspects of human research, completing tasks in minutes that might otherwise take hours.
OpenAI describes it as an autonomous agent that iterates on its findings, adjusting its approach as it uncovers new information. For example, a query about market trends could yield a report drawing from hundreds of online references, compiled in five to 30 minutes depending on scope. This capability distinguishes it from earlier chatbot models, which typically offer brief responses rather than in-depth analysis.

Timeline of Availability
The tool first became available to ChatGPT Pro users on February 2, 2025, a subscription tier costing $200 monthly. Pro users were initially limited to 100 queries per month, a cap later raised to 120. The focus on this premium group suggested an early emphasis on professionals—such as those in finance, science, or policy—who rely on extensive data analysis.
As of February 25, 2025, deep research is now accessible to subscribers of ChatGPT Plus, Team, Edu, and Enterprise plans, with a limit of 10 queries per month.

Technical Capabilities and Process
Deep research operates by taking a user prompt and independently exploring relevant online sources and uploaded files. It refines its focus through multiple passes, aiming to produce a coherent report that addresses the query. In a public example, OpenAI demonstrated the tool analyzing the translation app market, synthesizing data from numerous references into a concise summary—tasks that highlight its potential for efficiency.
The system card released alongside the announcement provides insight into its development, noting efforts to ensure accuracy and safety. However, OpenAI acknowledges that the tool’s outputs depend heavily on the quality of available data and the clarity of user prompts, limitations that could affect its reliability in nuanced scenarios.

Impact on Research and Workflows
The introduction of deep research has sparked discussion about its role in knowledge-based professions. In fields like academia or finance, where compiling data is time-consuming, the tool could reduce workloads by handling initial research phases. A scientist, for instance, might use it to gather background literature, while a policy analyst could track legislative trends across sources.
Yet, its scope has boundaries. The tool excels at aggregating and organizing information but lacks the interpretive depth of human expertise. Analysts have pointed out that it may struggle with ambiguous queries or fail to detect subtle biases in data, suggesting it’s best suited as a supplement rather than a standalone solution. OpenAI has framed it as a collaborative aid, not a competitor, to human researchers.

Context Within the AI Sector
OpenAI’s move comes amid heightened competition in AI research tools. Google’s Gemini Advanced and Perplexity’s Deep Research platform offer similar functionalities, with Perplexity providing a free, open-source option that has gained traction. This rivalry may have prompted OpenAI to widen access to deep research, reflecting a broader industry shift toward AI agents capable of independent task execution.
The trend extends beyond research. In finance, AI tools are already used to identify market signals, while in education, they assist with literature reviews. However, concerns persist about over-reliance on such systems, particularly if users accept outputs without scrutiny. The balance between automation and human judgment remains a key point of debate.

A Measured Assessment
The expansion of deep research to ChatGPT Plus users, following its Pro debut on February 2, 2025, marks a notable step in AI accessibility. Its ability to process and summarize vast datasets offers clear utility, particularly for those needing quick, broad overviews. Yet, its effectiveness hinges on user awareness of its strengths and shortcomings—namely, its reliance on existing data and limited capacity for critical nuance.
