Fable 5 and the CUDA Megakernel
Issue 464 of Jack Clark's Import AI newsletter highlights a significant milestone in AI-driven development: Fable 5 successfully writing a CUDA megakernel on the KernelBench-Mega benchmark [[47]]. This achievement demonstrates that advanced AI models can now generate highly optimized, low-level code that directly impacts hardware performance.
Automating Low-Level Research
The ability of an AI to write the kernels that make models faster hints at a broader future for AI research automation [[42]]. Instead of relying solely on human experts to squeeze out marginal performance gains, AI systems can now iterate on architectural optimizations autonomously, accelerating the entire machine learning development lifecycle.
The Rise of Analog Computation
In addition to software automation, the newsletter touches on emerging trends in analog computation. As digital scaling faces physical and economic limits, alternative computing paradigms are gaining attention as potential avenues for sustaining the exponential growth of AI capabilities.
