Live
Fine-tune open models
Dataset Lab inspects the file, then you pick a model and train LoRA/QLoRA on community GPUs. Pay per job — not for idle capacity.

Built on the OpenGPU Network
Your AI lab on open compute.
Fine-tune open models on community GPUs. Pay per job. CUDA and ROCm aware — without a cloud account, YAML, or terminal.

The platform
One product. Clear tools.
No agent factory. No fake capacity. Fine-tune is live on OpenGPU; the Lab grows as new tools ship.
Live
OpenGPU network
Jobs route to real NVIDIA and AMD providers. SmartRoute finds capacity; settlement and refunds follow a clear job lifecycle.

More tools
Playground and other tools land in the same workspace as they ship. Enter the Lab; pick what you need.

Fine-tune
From data to adapter in four steps.
The path that already runs in production — simple on purpose.
01
Dataset Lab
Inspect CSV/JSONL/TXT, map columns, pin eval rows. Nothing trains until the file is valid.
02
Pick model & preset
Open base models with Fast, Balanced, or Custom (epochs, LR, context, LoRA).
03
Route to a GPU
SmartRoute places the job on the OpenGPU network. No cloud GPU account.
04
Download adapter
When training finishes, get a secure download. Pay only what the job used.
DetectMap & cleanPin evalNo model reads your data. You only pay after the file is trainable. How Dataset Lab checks a file
Why OpenReef
Own the workflow, not a cloud bill.
Each piece stands alone. Together they form a lab on decentralized GPUs.
No YAML. No terminal.
A guided job flow instead of Docker, training configs and cluster scripts.
Decentralized compute
Real providers on OpenGPU — NVIDIA and AMD — with transparent job status.
Credits, not contracts
See price before confirm. Refund policy on failure. No monthly GPU tax.
Built to grow as a lab
Fine-tune is live. The Lab shell will host playground and future tools without a second product.
