The four-year partnership will fund vaccine research for neglected diseases, AI tutoring in sub-Saharan Africa, and public benchmarks. It dwarfs OpenAI's $50M Gates Foundation deal.

Anthropic is in talks to raise funding that would value it at between $900bn and $950bn, according to reports.

The partnership commits $200 million over four years to develop AI tools for use in vaccine research, farming guidance, education and other areas.
