OpenAI unveils slimmed-down ChatGPT deep research tool

OpenAI has announced the launch of a new version of its advanced tool 'Deep Research' integrated into ChatGPT, maintaining a high level of quality while introducing enhanced accessibility across user tiers.

The new version is powered by the 'o4-mini' model developed by OpenAI. According to the company, it is “nearly as intelligent” as the original version used for preparing in-depth, source-backed reports and summaries.

The updated tool delivers shorter responses while preserving the depth and accuracy for which OpenAI's models are renowned.

The lightweight version of Deep Research is now available to Free users of ChatGPT, with a maximum limit of five tasks per month.

Meanwhile, subscribers of the Plus and Team plans receive 25 tasks per month across both the original and lightweight versions. Pro plan subscribers are granted 250 tasks per month.

Starting next week, users on Enterprise and Education plans will also gain access to the new tool, with the same usage limits applied to the Plus and Team tiers.

Deep Research remains one of ChatGPT’s most advanced capabilities, enabling users to analyse websites and diverse online sources to generate comprehensive reports complete with clear references.
