# Chai Discovery: OpenAI Roots to Eli Lilly Deal in AI Drug Race

Chai Discovery, the AI startup with deep ties to OpenAI's founding team, has secured a landmark collaboration with pharmaceutical giant Eli Lilly and Company, accelerating the race to design next-generation therapeutics using frontier AI models.[2][5][7] This deal, announced amid Chai's recent $1.3 billion valuation following a Series B funding round, positions the company as a frontrunner in AI-driven drug discovery, blending computational power with Lilly's vast proprietary data.[2][5]

Chai Discovery's OpenAI Origins Fuel Rapid Rise

Chai Discovery emerged from the talent pool of OpenAI, with key figures leveraging expertise in frontier AI models to tackle biologics design.[7] Founded by veterans from OpenAI's offices, the San Francisco-based startup quickly gained traction, culminating in a Series B round co-led by Oak HC/FT and General Catalyst in December 2025.[2] CEO Josh Meier emphasized the synergy: "Our collaboration with Lilly brings together Chai’s expertise in building frontier models with Lilly’s ability to deploy technology to accelerate their efforts."[2] This OpenAI heritage has enabled Chai to develop a computer-aided design suite for molecules, now deployed for Lilly to target multiple therapeutic areas.[2][7]

Eli Lilly Deal Unlocks Custom AI for Biologics Breakthroughs

Under the partnership, Eli Lilly will access Chai's AI platform to design novel biologic therapeutics, including a purpose-built model trained exclusively on Lilly's proprietary data and workflows.[2] Following successful evaluations of Chai's initial model designs, the collaboration aims to expand AI boundaries in early-stage drug discovery.[2] Aliza Apple noted expectations for first-in-class medicines to enter clinical trials by the end of 2027 through such 2026 partnerships.[7] Investors like Annie Lamont of Oak HC/FT hailed Chai as "the leader in building frontier models to reshape the category," signaling a shift toward computer-designed novel medicines.[2]

AI Drug Race Heats Up with Nvidia-Lilly Mega-Investment

Eli Lilly's AI push extends beyond Chai, with a parallel up-to-$1 billion joint investment alongside Nvidia to launch a co-innovation lab in South San Francisco.[1][3][4] Set to open later in 2026, the lab will unite Nvidia's AI experts and Lilly's researchers to reinvent drug discovery through in silico exploration of biological spaces.[3][4] Nvidia CEO Jensen Huang described it as a "new blueprint" featuring continuous learning systems linking wet labs to AI models, alongside tools like BioNeMo and Omniverse for digital twins in production optimization.[3][4] This complements Lilly's TuneLab platform, which shares Clara models with biotechs via partnerships like Benchling.[3][6]

Broader Implications for Pharma's AI Transformation

These alliances underscore AI's profound impact on life sciences, from accelerating discovery to streamlining manufacturing.[4][6] While forward-looking statements highlight potential risks in drug development, the momentum—evident in deals like AstraZeneca's Modella AI acquisition—positions 2026 as a pivotal year for AI-native therapeutics.[6] Chai's Lilly deal, rooted in OpenAI innovation, amplifies this trend, promising faster paths from computation to clinic.[2][7]
