Large Scale AI on Apple Silicon (as mentioned by @AndrejKarpathy ) — Alex Cheema, EXO Labs

Introduction to AI and Historical Context 00:01

  • The video discusses the relationship between AI and scientific rigor, starting with historical scientific challenges at the turn of the 20th century involving energy quantization.
  • Max Planck proposed that energy is quantized to resolve an issue in physics, leading to experimentation by Robert Millikan to measure a constant associated with electric charge.

Importance of Scientific Rigor 03:11

  • Scientists faced embarrassment and inertia as they conformed to incorrect prior results, demonstrating the challenges of scientific validation.
  • A second example involving rat experiments illustrates how assumptions can lead to incorrect conclusions in scientific research.

AI Development and Historical Skepticism 08:29

  • The video connects historical scientific skepticism to the evolution of AI, noting how backpropagation and convolutional neural networks faced skepticism even after being introduced.
  • The bottleneck of existing hardware (like CPU limitations) delayed the acceptance of revolutionary AI ideas for decades.

The Hardware Lottery 10:33

  • The concept of "hardware lottery" is introduced, emphasizing that the best research ideas do not always prevail due to hardware constraints.
  • Large Language Models (LLMs) create a feedback loop, enhancing their own utility while potentially sidelining other programming languages.

Exo Labs and New AI Approaches 12:05

  • Alex Cheema discusses Exo's mission to create an orchestration layer for AI that works across various hardware targets, addressing current limitations in device integration.
  • Exo aims to build a causal graph model for event tracking in distributed systems, enhancing reliability and efficiency.

Innovative Optimizers and Apple Silicon 14:35

  • The presentation highlights research on optimizing AI training on Apple Silicon, which offers more memory but may be costlier per computation.
  • Exo is developing a new optimizer that is more efficient than existing methods, leveraging Apple's memory advantages to improve training processes.

Commitment to Transparency in Research 16:11

  • Cheema emphasizes the importance of sharing both successful and unsuccessful research results to foster scientific progress.
  • Upcoming benchmarks and tools will be made publicly accessible, allowing broader experimentation with AI workloads.

Future Developments at Exo 17:18

  • Exo plans to release a new orchestration layer and tools for testing various algorithms across hardware platforms, enhancing accessibility for researchers.
  • The focus will be on building a reliable framework that can accommodate diverse AI workloads effectively.

Q&A Segment 18:22

  • A brief Q&A session addresses technical comparisons between different hardware platforms and collaboration with other teams working on AI infrastructure.
  • Cheema discusses the ratio of performance metrics rather than absolute numbers, highlighting the need for targeted improvements in specific areas of AI research.
