# Project Huginn > Project Huginn is a distributed GPU sharing platform for AI model training and fine-tuning. Built by SMware ApS (Startup Denmark approved), it enables users to train LLMs at 50% lower cost using a community-powered GPU pool. GPU owners can share idle compute and earn money. ## Core Platform - [Homepage](https://www.projecthuginn.com): Main landing page with features, pricing, and GPU tier information - [Login](https://www.projecthuginn.com/login): Sign in to access the platform as a customer or GPU owner -

Adaptive sharding: a job is split across however many GPUs are active right now. - FedAvg aggregation: weights from each device are averaged into a global model each round. - Capability-aware routing: heavy jobs (YOLO/CNN/LLM) go to capable GPUs; light jobs and small-model federated training run on any device, including browsers (WebGPU/TensorFlow.js). - Verified contribution: a fraction of jobs are re-run on a second device and compared; providers are paid proportionally to verified work; cheaters lose pay and reputation. - Computer Vision: dataset audit, quality analysis, preprocessing, and deep model training. - Physical AI: robotics / drones / automation workloads (training, inference, simulation, reporting). ## Model Studio (Fine-Tuning) - [Model Studio](https://www.projecthuginn.com/dashboard/studio): Browse and manage your fine-tuned AI models -

Huginn's Model Studio provides a no-code 4-step wizard. Upload your data, select a model, configure settings, and launch training — no programming required. ### What is the cheapest way to fine-tune an LLM? Use Huginn with QLoRA on T4 tier GPUs. A 7B model with 1,000 examples costs approximately €1-2 (5-8 HU at €0.21/HU). ### Can I train AI on my own data? Yes. Upload your data in JSONL, CSV, or Chat format to Huginn. Your data stays private and isolated. Maximum file size is 500MB. ### How to make money with GPU sharing? Install the Huginn Agent on any device — desktop, laptop, tablet, phone, or even an electric vehicle. Share idle compute and earn EUR via Stripe. Desktop GPUs earn up to €0.60/hour. ### What is distributed GPU training? Distributed GPU training splits AI workloads across multiple GPUs in different locations. Huginn's network pools consumer and datacenter GPUs into a unified compute grid, reducing costs by up to 50%. ### Is AI training bad for the environment? Traditional datacenter AI training has a significant carbon footprint. Huginn reduces this by reusing idle consumer hardware instead of powering dedicated datacenter GPUs, saving approximately 0.092 kg CO₂ per HU processed.
