Case Study: JLL’s Implementation of JLL GPT™

JLL, a leading global commercial real estate firm, has launched JLL GPT™, a bespoke generative AI designed specifically for the commercial real estate (CRE) industry. This innovation marks a significant advancement in JLL’s commitment to integrating technology into its services, enhancing its capabilities in real estate insights, consulting, and investment opportunities. The implementation of JLL GPT™ showcases JLL’s strategy to leverage cutting-edge technology to provide superior service and insights to its clients globally.

Key Takeaways

  • A specialized large language model, JLL GPT™, has been introduced to enhance commercial real estate insights on a global scale.
  • JLL has enriched its extensive internal data with external sources to deepen its insights.
  • The application of AI has upgraded tools used for real estate management, investment, and consulting services.
  • Clients benefit from faster, more intelligent decision-making capabilities.


JLL’s approach to integrating AI within its operational framework focuses on developing internal capabilities through JLL Technologies (JLLT), its technology division. By leveraging both internal and external CRE data, JLL has crafted a bespoke AI model that is deeply aligned with the industry’s specific needs. This strategic move is part of JLL’s broader data-first philosophy, which emphasizes the importance of quality data in powering AI solutions.


JLL GPT™ was developed and implemented within a secure computing environment to ensure compliance with the firm’s stringent privacy and security standards. The technology is utilized across various divisions including facility management and consulting, transforming traditional real estate management tools into advanced, AI-driven platforms. For instance, JLL’s facility managers use AI to convert standard dashboards into dynamic systems that enhance space utilization and portfolio optimization.


The deployment of JLL GPT™ has already yielded significant improvements in operational efficiency and client service. For example, in JLL’s Capital Markets, AI technology has enabled the identification and optimization of investment opportunities, where one in five opportunities was facilitated by AI in early 2023. Furthermore, the introduction of dynamic tools powered by AI has allowed for quicker and more comprehensive planning advice, enhancing decision-making processes and client outcomes.

Challenges and Barriers

While JLL has successfully integrated AI into its operations, the transformation has not been without challenges. These include ensuring data privacy, maintaining the integrity of client data, and adapting the workforce to new technologies. Additionally, the vast amounts of unstructured data in multiple languages presented initial hurdles that JLL has been addressing through generative AI and LLMs, aiming to streamline data processing and integration.

Future Outlook

Looking ahead, JLL plans to expand its AI capabilities, with over 40 innovations currently in development or beta stages. The firm remains committed to enhancing its technology offerings, focusing on sustainability and efficiency through tools like Carbon Pathfinder and other AI-driven solutions.
