When to use it

Distributed training orchestration across clusters. Scales PyTorch/TensorFlow/HuggingFace from laptop to 1000s of nodes. Built-in hyperparameter tuning with Ray Tune, fault tolerance, elastic scaling. Use when training massive models across multiple machines or running distributed hyperparameter sweeps.

Example requests

Ask your agent in plain language, for example:
  • “How do I run my PyTorch training across 4 machines with 8 GPUs each?”
  • “My train.py fine-tunes a Llama-style model with HF Trainer on a single A100 and I now have a 6-node Ray cluster. Running ray status shows only the head node, and workers fail with ‘Unable to connect to GCS at 10.0.0.5:6379’. How do I get this training across the whole cluster with checkpointing so it survives a node dying?”
  • “I need to find the best learning rate, weight decay and batch size for my ResNet on our shared cluster. I’d like to try a couple hundred configs in parallel and stop the bad ones early. What’s the approach?”

Install

In Claude Code you can also add the marketplace with /plugin marketplace add KalarisLabs/research-agent-skills and install the whole ml-training category with /plugin install ml-training@research-agent-skills.
