Workers are beginning to make tasks outside their traditional occupations a recurring part of their AI-assisted routines, according to OpenAI research based on more than 1.5 million work-related ChatGPT messages from April through July 2026. The finding suggests job content may broaden before job titles or organizational charts change.
Among about 6,200 workers observed throughout the four months, previously used cross-occupation tasks rose from 13.1% of occupation-specific AI activity in April to 25.9% in July. In a separate matched analysis, workers returned the next month to a cross-occupation task 23.6% of the time, versus 8.4% among comparable workers who had not previously used that task. Return rates varied sharply: customer discussions reached 54%, promotional writing 44%, and explaining financial information about 15%.
The data shows behavior inside ChatGPT, not whether the resulting work was accurate or whether employers formally changed responsibilities. OpenAI says occupations were inferred from role or department information supplied during Business onboarding; messages were aggregated and anonymized, and researchers did not read individual messages. The practical takeaway is that access to AI alone may not determine adoption—companies may also need to redesign workflows and decide which newly accessible tasks belong in each role.
