Project Huginn
cheaper AI training on idle GPUs
Last verified:
What is Project Huginn?
Project Huginn is a distributed GPU sharing platform that enables users to train and fine-tune AI models at up to 50% lower cost than traditional cloud providers. The platform pools idle GPU compute power from consumer and enterprise devices across the globe, including smartphones, electric vehicles, desktop GPUs, and datacenter GPUs, creating a decentralized network for AI training without massive infrastructure overhead.
The platform offers two main capabilities: standard fine-tuning of open models (LLaMA, Mistral, Phi, Gemma, Qwen) using LoRA and QLORA techniques, and Hugin Learning, their proprietary breakthrough that trains control intelligence for robots, drones, and automation from scratch through trial-and-error without labelled data. Users can build custom language models for chatbots and assistants, computer vision models for object detection and quality control, and robotics perception models.
Security and privacy are central to the platform with Hugin Shield+, which keeps data encrypted and split so no single machine ever sees the complete dataset, and Vault, which runs jobs on sealed hardware for the most sensitive work. Every result is independently re-checked, and slow or dropped machines never stall jobs, ensuring verified and reliable model delivery.
The platform targets AI researchers, robotics teams, drone developers, automation engineers, and anyone needing to train production-ready models including custom language models, computer vision models, and robotics control policies. Users upload their data through a no-code Model Studio, configure training settings, train across the network, and download finished models ready to use anywhere.
Project Huginn pricing
Pricing model: Freemium
Project Huginn uses transparent HU (Hugin Unit) billing at 0.21 EUR per HU. 1 HU equals approximately 3,600 normalized GPU-seconds. Users can pre-estimate and get an upper bound before every job. Fine-tuning a 7B parameter model with 1,000 examples using QLoRA on T3/T4 tier GPUs costs roughly 5 to 10 HU (around €1 to €2). The platform offers three pool options: Community, Verified, or Dedicated. Shield+ protection is included at the standard rate, while Vault adds hardware isolation for sensitive data at additional cost. The platform provides ESG reporting with kWh/HU and CO₂e/HU metrics. Device classes earn different HU rates: Smartphones (0.05-0.15 HU/hour), Electric Vehicles (0.2-0.4 HU/hour), 4-6GB Consumer GPUs (0.4-0.6 HU/hour), 8-12GB Consumer GPUs (0.6-0.9 HU/hour), 16-24GB Workstation GPUs (1.6-2.8 HU/hour), and 24-48GB+ Datacenter GPUs (2.8-4.5 HU/hour).

Frequently asked questions about Project Huginn
What is Project Huginn?
Project Huginn is a distributed GPU sharing network that pools idle compute power from consumer and enterprise GPUs across the globe. Instead of relying on a single data center, it connects people who need GPU power for AI training with people who have idle GPUs sitting around, enabling AI model training at up to 50% lower cost than traditional cloud providers.
How does Hugin Learning work?
Hugin Learning is Project Huginn's proprietary breakthrough that trains control intelligence for robots, drones, and automation from scratch through trial-and-error without needing labelled data or demonstrations. The system discovers the right behaviour by trial-and-error, learning to balance, position, navigate, and perform custom tasks. It's trained and verified across the distributed network, with every result independently re-checked.
What is HU (Hugin Unit)?
HU (Hugin Unit) is Project Huginn's transparent billing currency. 1 HU equals approximately 3,600 normalized GPU-seconds. The rate is 0.21 EUR per HU. Users can pre-estimate costs and get an upper bound guaranteed before every job, making pricing transparent and predictable for AI training workloads.
How does Hugin Shield+ protect my data?
Hugin Shield+ is a multi-layer protection stack that keeps your data encrypted and split so no single machine in the network ever sees the complete dataset. This is different from most GPU networks that ship raw data to strangers' machines. Shield+ is included at the standard rate with every job, providing private-by-design protection.
What is Hugin Vault?
Hugin Vault is an optional protection level that runs jobs inside hardware-isolated sealed hardware that no one else can read. It's designed for the most sensitive data work where maximum security is required. Vault adds hardware isolation beyond Shield+ and comes at additional cost for the most sensitive data protection needs.
What models can I fine-tune on Huginn?
You can fine-tune open models including LLaMA, Mistral, Phi, Gemma, and Qwen using LoRA and QLORA techniques on your own data. The no-code Model Studio lets you select a free base model, upload your JSONL or CSV dataset, configure LoRA/QLoRA settings, train, and immediately test it in the built-in Playground for chatbots, assistants, code, and multilingual applications.
How much does it cost to fine-tune a model?
Using QLoRA techniques on T3/T4 tier GPUs, fine-tuning a 7B parameter model with 1,000 examples costs roughly 5 to 10 HU, which is around €1 to €2 at the 0.21 EUR per HU rate. This is significantly cheaper than traditional cloud providers, offering up to 50% cost reduction for AI training workloads.
What devices can share compute on Huginn?
Huginn harnesses compute power from any connected device globally: Smartphones (via Browser or App like iPhone 15 Pro and Pixel 8), Electric Vehicles (like Tesla MCU and Polestar 2), any Web Browser Tab, and Desktop & Server GPUs ranging from consumer GPUs (GTX 1650, RTX 3050, RTX 3060, RTX 4070) to workstation GPUs (RTX 3090, RTX 4090) and datacenter GPUs (A100, H100).
How does Project Huginn verify results?
Every result on Project Huginn is independently re-checked across the network. A slow or dropped machine never stalls your job because the distributed system continues processing regardless of individual machine issues. This verification process ensures you get a model you can trust with completely hands-off delivery.
What AI projects can I build on Huginn?
You can build custom language models for chatbots, assistants, code, and multilingual applications; computer vision models for image classification and object detection used in quality control, drones, cameras, and inspection; robotics and automation perception models with dataset preparation, augmentation, validation, and benchmarking; and use Hugin Learning to train control policies for robots and agents that discover behaviour from scratch.
