Overview

Client library and `lep` command-line tool for the NVIDIA DGX Cloud Lepton platform. It creates and manages endpoints, Dynamo graph deployments (vLLM, SGLang, TensorRT-LLM), batch jobs, dev pods, Ray clusters, and Slurm inspection. A Python `Client` calls deployed endpoints as functions, and a bundled skill lets Claude Code or Codex drive the CLI.

Who it is for: Users of NVIDIA DGX Cloud Lepton who deploy and manage GPU workloads

Strengths

  • Single CLI covers endpoints, jobs, dev pods, Ray clusters, Dynamo deployments and Slurm inspection
  • Dynamo commands support multi-node and disaggregated prefill/decode with vLLM, SGLang or TensorRT-LLM
  • Shell access through workspace API over HTTPS, no SSH keys needed; Teleport SSH also supported
  • Ships a Claude Code and Codex plugin that asks confirmation before modifying workloads

Weaknesses

  • Only works against NVIDIA DGX Cloud Lepton; it is not a self-hostable serving stack
  • Requires a Lepton workspace account and login to do anything useful
  • Teleport SSH needs a local tsh v18+ and workspace-side Teleport enablement
  • Slurm job submission and cancellation stay outside the CLI; it only inspects

What it needs

  • Needs NVIDIA DGX Cloud Lepton workspace, tsh v18+ (optional, for Teleport SSH)
  • Models: vLLM, SGLang, TensorRT-LLM

Quick answers

Is leptonai open source?
