“Our established relationship with BCS served as a sturdy foundation for innovative collaboration in this emerging field,” says Michael Seemann, Life Sciences Partner, Ernst & Young LLP. “We quickly assembled a team comprised of experienced people in agribusiness, strategic planning, and GenAI technology to identify the business opportunities and potential value of AI within Bayer.”
The LLM, built in the Microsoft Azure environment, was grounded with decades of aggregated agronomy content, product research data and proprietary insights. With additional information stored on BCS’s legacy systems in traditional formats (i.e., spreadsheets and tables), the team worked hard to translate the information into a structure the GenAI system could comprehend. But the information discovery did not stop there. The team used algorithms to format information from different sources into digestible data to further inform the GenAI system.
"The success of a GenAI solution depends on two critical factors: the quality of the data used as foundational elements within the technology, and the relationships and patterns established within that dataset," notes Dan Diasio, EY Global Artificial Intelligence Consulting Leader. "Bayer’s GenAI solution excels in both aspects."
The team needed to construct the GenAI system to understand the context and detail of natural language queries. For example, the system had to be able to answer, “What is the greensnap rating for the DKC25-15RIB corn seed?” which relates to a seed corn product’s ability to withstand high winds during the period of rapid growth.
The team employed Retrieval Augmented Generation (RAG) methodology that could dynamically retrieve relevant information to respond, in real time, to prompt inquiries. Prompt engineering was also used to further tailor the GenAI system’s responses to help ensure accuracy and subsequently outperform open-source LLMs currently serving the market on applied agronomy questions.
To assess the system's capabilities, the team designed a sophisticated scoring system that compared responses from the GenAI system, open-source LLMs and subject- matter experts (SMEs). The question set was then further expanded, and an automated validation process was built. The results were impressive. By the end of the 90-day POC, the GenAI system was answering with outstanding accuracy across every topic building great confidence in the team and users.
“It’s our obligation to apply the benefits of AI responsibly and conscientiously,” says Edward Bobrin, Executive Director, Technology Consulting, Data and AI Leader, Ernst & Young LLP. “EY teams have a profound understanding of both the potential of AI and associated risks.”
“In some respects, the system is able to surpass what a single individual can store in their brain,” said Kurdys. "It may not supersede the knowledge of an expert on a specific topic. However, it is a powerful aid in the hands of agronomists based on its knowledge recall speed and breadth of information accessible. This illustrates the true potential of the technology.”
