The agent-first GPU cloud

GPU instances for developers. Full Ubuntu sandboxes for agents running ML experiments, CUDA code, and other GPU workloads.

Products

Instances for developers, GPU sandboxes for agents

Instances for hands-on development and sandboxes for RL environments and evals at scale

Instances

A GPU instance you connect to and keep. Snapshot it when you are done.

~ zsh
$ tnr create --gpu a100
✓ Instance 0 created
$ tnr connect 0
✓ Connected to instance 0

Sandboxes

Run RL tasks, evals, and CI jobs that need a GPU in isolated Ubuntu VMs. Scale out in parallel and pay per second for the compute each task needs.

A full computer for your agent

Run the tools, dependencies, and services your task needs in its own Ubuntu VM.

agent.py
import thunder_sandbox as thunder
sandbox = thunder.Sandbox.create(
    cpu=4, memory=32, storage=50,
    gpu_type=thunder.GPUType.H100, gpu_count=1,
    timeout=900)
sandbox.wait_until_ready()
process = sandbox.exec("nvidia-smi")
