OpenAI has introduced a new "lightweight" version of its ChatGPT deep research tool. This feature will be accessible to ChatGPT Plus, Team, and Pro users. The tool will sift through online sources and generate research reports, offering shorter responses while maintaining high quality. It operates on OpenAI's o4-mini model.

Advantages of the Tool
Although the lightweight version may not match the full version in capabilities, OpenAI emphasizes its cost-effectiveness, allowing for increased usage limits. According to OpenAI, responses will be concise yet uphold the expected depth and quality.
Future Expansion
OpenAI plans to extend the lightweight research tool to enterprise and educational users in the coming week, providing them with similar usage levels as Team users. This move aligns with a broader trend where various chatbots like Google's Gemini, Microsoft's Copilot, and xAI's Grok have recently integrated their own deep research tools supported by AI reasoning models.
