Problem

Petrobras wanted to reduce effort spent preparing reports and other workplace documents while protecting internal information.

Approach

Petrobras developed ChatPetrobras with Microsoft using GPT through Azure OpenAI Service. An internal portal made it available to employees and contractors. It supported document drafting and answered user questions within the company's information-security framework.

Results

110,000employees and contractors with access to the internal portal, not confirmed active usersVendor case study[1]

Takeaway

Availability to the workforce did not establish active usage. Time and cost reductions remained expected benefits.
