The lightweight version of deep research is powered by a version of OpenAI o4-mini and is nearly as intelligent as the deep research people already know and love, while being significantly cheaper to serve.

Responses will typically be shorter while maintaining the depth and quality you’ve come to expect.

Once limits for the original version of deep research are reached, queries automatically default to the lightweight version.
