About
Osium AI is a United States-based AI materials discovery platform — backed by Y Combinator (S23) with $3.1 million in total funding including a $2.6 million seed in 2023 from Y Combinator, Singular, Kima Ventures, Collaborative Fund, and Raise Phiture — providing materials R&D engineers and industrial companies with AI software that accelerates the discovery and optimization of new materials by 10x, predicting physical and chemical properties of candidate formulations before laboratory synthesis. Founded in 2023 by Stanford University friends Sarah Najmark and Luisa Bouneder, Osium achieved a partnership with Aperam (a global stainless and specialty steel producer) in October 2024 and partnerships with leading research institutions in November 2024 — validating the platform's utility for industrial materials development.

About
Grok is the AI assistant developed by xAI, Elon Musk's AI company founded in 2023, and distributed primarily through X (formerly Twitter). Grok launched in November 2023 as an X Premium perk, with the notable differentiator of real-time access to X posts and a less restricted, more direct conversational style. Grok 3, released in February 2025, achieved top scores on the AIME math reasoning benchmark and ARC-AGI test, briefly positioning xAI as a frontier model lab.
