    Autoresearch from @karpathy runs 1 experiment at a time. We gave it 16 GPUs and let it run them in parallel. 8 hours. 910 experiments. 9× faster to the same best result. The most surprising part: the agent had access to both H100s and H200s. Without being told, it noticed H200s

    Karpathy's Autoresearch is bottlenecked by a single GPU. We removed the bottleneck. We gave the agent access to our K8s cluster with H100s and H200s and let it provision its own GPUs. Over 8 hours: • ~910 experiments instead of ~96 sequentially • Discovered that scaling model

    "sbatch and forget." That was the promise of Slurm, and it worked great. Until we got a second GPU cluster. Suddenly: Which cluster did I submit to? Which one has free GPUs? Should I move my job? I wasn't just submitting jobs anymore. I had become part of the scheduling system,

    Managing multiple Slurm clusters is painful. Each cluster has different login nodes, partition names, and environments. Managing them manually is time-consuming, error-prone, and a bottleneck as your team scales. SkyPilot provides you with: • One unified interface to access

    I am so excited for this new company! I’ve been following @quocleix ’s work since the first NAS paper a decade ago, and really honored to have @JeffDean supporting our @skypilot_org company from day one. With the new capability of agents, the search space has been enlarged

    Excited to have the Day-0 support for Kimi-K3 @skypilot_org! A single command, start production-ready serving for K3 across your own GPU clusters.

    Kimi K3 is out. 2.8T parameters. 1.4 TB of weights, frontier-level performance. Serving it on your own infra is the hard part - you need multi-node inference spread across every cluster you can grab capacity from. And then autoscaling, cache-aware routing, PD disaggregation - an
