Doolhof Linux is a small Alpine-based distribution that boots in under 90 seconds onto Lambda Cloud GPUs. Encrypted ephemeral disk, pre-configured ML stack, pay-per-second after the first 10 minutes.
Raw cloud GPUs carry a long tail of setup: drivers, frameworks, network rules, key rotation, cleanup. Managed platforms remove the setup burden but extract metadata as the trade. Doolhof Linux delivers the first without the second.
Every session boots with a freshly-generated LUKS key held in RAM only. When the session ends, the disk is cryptographically destroyed — not deleted, unrecoverable.
No long-running state. No background daemons. Each session is a clean room. Optional persistent volume available by explicit opt-in.
Built on Alpine Linux for minimum attack surface. musl libc, OpenRC init, no systemd. Base image under 200 MB before framework layers.
CUDA 12.4, PyTorch 2.6, JAX, vLLM, llama.cpp, HuggingFace transformers, ComfyUI — installed and current. Jupyter URL on launch. SSH key auto-injected.
10-minute minimum, then per-second metering. Stop a session and billing stops within 5 seconds. No rounding to the hour.
Provisioned on Lambda Cloud's GPU fleet — the most competitive H100 and A100 capacity outside the hyperscalers. Lambda provides the hardware. Doolhof Linux provides the runtime layer.
Most users are running code within 90 seconds of pressing Launch.
H100 80GB, A100 40/80GB, A6000 48GB, or RTX 6000 Ada. Soft duration that can be extended or stopped at any time.
The platform provisions the Lambda instance, boots Doolhof Linux, mounts an encrypted ephemeral disk, configures the stack, and delivers SSH plus Jupyter URLs.
SSH or browser Jupyter access. Upload datasets, train models, run inference. Stop when finished — disk is cryptographically destroyed on session end.
No volume tiers, no commitments, no enterprise upsells. Per-second metering with a 10-minute minimum.
Pricing includes the $0.12/hour Doolhof Linux runtime fee. Lambda's published GPU rates apply for compute underneath.
A clear statement of what Doolhof Linux protects, and what falls outside its guarantee.
Disk encryption with per-session keys. Network isolation between sessions. No logging of session contents. Cryptographic disk destruction on session end. Audited bootstrap scripts.
Lambda Cloud operates the underlying GPU hardware. Their facility security, hardware attestation surfaces, and side-channel exposure are not under Doolhof Labs' control. Workloads requiring confidential computing should use Nitro Enclaves or H100 confidential mode separately.
Bootstrap scripts, network policies, and the billing meter are published. Customers may verify what runs on their behalf.
The first cohort of customers is being onboarded now. Initial sessions provisioned within one hour of access approval.
