In week three of CS 153, the instructor hosts Amit Jain from Luma to discuss “Unified Intelligence Systems” as a follow-up to a prior lecture on visual intelligence. Jain recounts his Apple work on LiDAR for projects including Titan and Vision Pro, and how early exploration of generative models and differentiable 3D led to founding Luma with an initial focus on large-scale 3D capture. Luma then shifted to generative video in 2023 to leverage the scale of internet video data, releasing the Dream Machine model in March 2024 and rapidly reaching millions of users, while building preference-based feedback loops and human annotation pipelines. Jain explains Luma’s multimodal AI factory—pretraining, post-training, deployment, and reinforcement learning—its security constraints for studio clients, and a move toward unified transformer architectures that jointly reason across text, images, video, and audio to enable end-to-end creative and professional workflows.
