Through its Grand Challenge, Gates Foundation has selected 48 research groups that plan to build artificial intelligence (AI) applications on large language models (LLMs) to help social and healthcare causes in their communities.

About 29 of the recipients are Africans. 13 are from Asia, and the other six are American researchers. Each recipient will receive up to $100,000 to advance their research project, for a total of $5 million in grants. The findings of these projects will be shared at the Grand Challenges Annual Meeting in Dakar, Senegal, this October.

“These local innovators are harnessing the seismic power of AI and LLMs in ways that can be paradigm-shifting for their local communities and beyond. We believe the most impactful technological advancements include those that begin and end with the people they affect most,” Zameer Brey, interim deputy director for Technology Diffusion at the Gates Foundation, said.

“Too often, advances in technology deliver uneven benefits in many parts of the world due to existing patterns of discrimination, inequality, and bias,” said Juliana Rotich, co-founder of iHub, a Nairobi-based tech incubator that has been acquired by CcHub. “AI is no different, with most of the tools being developed in the Global North using data from lower-resourced regions that are often incomplete or inaccurate. To realize the full potential of AI, it must be developed responsibly and ethically, with the needs of the end user in mind. Solutions can be transformative when they are locally inspired.” Rotich is also a member of Gates Foundation's new AI Ethics and Safety Advisory Committee.

Responsible and safe use of AI-driven LLM technology has the potential to help solve some of the world’s toughest health and development challenges. However, for these models to be useful in low- and middle-income countries (LMICs), researchers in LMICs need to participate in the design, application, and testing of this technology as it rapidly evolves. A robust evidence base will fill gaps in access and our knowledge about the application of such tools to address problems across LMICs in an equitable way.
