@typesafeai achieved 46% higher GPU throughput while training Jev using @zymtrace’s cluster-wide, continuous profiling and agentic optimization platform.
See how they did it in the link below 👇

Excited to have my friend and former co-worker @RobFergusonIII on our monthly AI Performance Engineering webinar! Having developer AI startup accelerator programs at both AWS and Azure, Rob will discuss how AI startup founders can extract the most value out of these AI accelerator programs including token maxxing, outcome maxxing, and fund-raise maxxing! See you all Monday morning at 9am PT! @anbarth
