# Jaroslav Beck

> Founder of BottleCap AI. Previously co-founded Beat Games (Beat Saber). Personal site: https://jaroslavbeck.com

Jaroslav Beck is building the European AI research lab BottleCap AI with Tomas Mikolov (word2vec, pioneer of modern NLP). BottleCap builds efficiency-first LLMs: smaller, faster, more cost-efficient models without losing accuracy. The lab focuses on brand-new algorithms that lead to new architectures with the ambition to challenge transformers, and invents new AI apps such as AI Scan for potential biases inside LLMs.

Previously he co-founded Beat Games, the studio behind Beat Saber (10M+ copies, Best VR/AR Game at The Game Awards 2019). Meta acquired Beat Games in 2019. He led the Beat Games studio at Meta until 2023.

Before Beat Saber he composed cinematic music for games and film, including StarCraft II: Legacy of the Void (G.A.N.G. Award, Best Cinematic / Cutscene Audio, as part of the team), Overwatch shorts, Battlefield, Heroes of the Storm, and spots for Star Wars: The Force Awakens and Terminator Genisys.

Born 1988 in Strakonice, Czechia.
