Sam Sinha Leaves Luma AI After Four Years And Uni-1 Release

Original post

After 4 incredible years, today marks my last day at @LumaLabsAI. I’m so proud to have helped build the company from 5 to 250 people. Luma started as a humble attempt at bringing NeRFs to smartphones in 2022, and is currently an extremely successful startup capable of training frontier models that can truly compete with the best generative models in the world. I have so much love and respect for the whole team but I want to give a special thanks to @baaadas - for trusting me 3 years ago and deciding to join Luma and help us be a serious generative AI company, and then for building a culture that allowed me to do my best work ❤️ Finally, I’m so proud of our most ambitious and impressive model release: Uni-1, an industry defining unified multimodal model that will shape the future of the company, and the field for years to come. Working relentlessly on the project with some of my favourite people was the highlight of my career thus far. This project wouldn’t be possible without @shenbokui for his leadership and the rest of the Omni team for the incredible execution and dedication to the mission 🚀 Will take a week off to visit 🇨🇦 but have some exciting updates to share soon after 👀
