Frequently asked questions
Is the library really free?
Yes. The full AiDotNet library — all 7,300+ classes, every neural network, every ML algorithm, every vision model, full GPU acceleration — is open source under the Apache 2.0 license. You can use it in any project, commercial or otherwise, forever.
What does Pro add?
Pro gives you cloud-hosted inference API endpoints so you can deploy your trained models without managing servers. It also includes model encryption to protect your intellectual property, API key management for distributing models to your customers, and priority support with direct access to the engineering team.
Do I need Pro for GPU acceleration?
No. GPU acceleration on NVIDIA, AMD, and Intel GPUs, SIMD optimizations, and all performance features are included in the free tier. Pro is for cloud deployment, model protection, and support.
How is this different from Hugging Face or W&B?
AiDotNet is a native .NET library — everything runs in your .NET process without Python, Docker, or external runtimes. Hugging Face and W&B are Python-centric platforms. If your stack is .NET, AiDotNet integrates directly with zero overhead.
Can I switch plans?
Yes. You can upgrade, downgrade, or cancel at any time. If you switch from monthly to yearly, you'll get a prorated credit for the remaining time on your current billing period.
