Deep Research can interpret and analyze text, images, and PDFs.^[4] It is based on a specialized version of OpenAI's o3 model.^[4]

Deep Research scored 26.6% on the "Humanity's Last Exam" benchmark, outperforming rivals like DeepSeek's model R1 (9.4%) and GPT-4o (3.3%).^[5]

Deep Research is currently offered to ChatGPT Pro subscribers ($200/month), who receive 250 queries per month (150 of which being 'lightweight'), to Plus, Team and Enterprise users who receive 25 queries per month (15 of which being 'lightweight'), and to Free users, who receive 5 'lightweight' queries per month.^{[citation needed]}
