Vast AI Review and Pricing
Basically, Vast.AI is a place where one can rent powerful computers with GPU on the cloud, at a low price. In short, it is an alternative to Amazon Web Services (AWS) and also Google Cloud Platform (GCP).
The main advantage of Vast.AI is its much lower price, compared to AWS and GCP. For example, one is able to rent GPUs at just $0.1 per hour, where other platforms typically charge dollars per hour.

There are two modes of rental on Vast.AI: interruptible and on-demand. The interruptible mode is on a constant bidding basis, with the highest bidder able to take over the GPU usage rights at any time. The good point is that the interruptible mode rentals are extremely cheap.
The on-demand mode is slightly more expensive, but the advantage is that the user can rent the GPU at the fixed price throughout the period, without worrying about another user outbidding.
Vast AI Stable Diffusion Guide
Vast.AI is popularly used for the Stable Diffusion AI image generation program. They have a detailed guide on their website on how to use Stable Diffusion with Vast.AI.
The above guide provides guidance on how to implement stable diffusion using Vast.AI’s platform. It explains the necessary steps, including configuring the account, picking a Web UI template, and creating art using artificial intelligence.
Vast AI Profitability
Vast AI offers GPU owners the opportunity to rent out their GPUs. The profitability of Vast AI rental is high, and is said to be ~2x to ~4x more per GPU-hour than mining cryptocurrency.
This would be a good opportunity for GPU owners to monetize their idle GPUs, especially during the recent years where there is high demand for GPU for training deep learning models.
Start Using Vast.AI
To start using Vast.AI, simply create an account on the website. The set up process is relatively simple, one just needs to first top up credit using one of the accepted payment options (credit card via Stripe, or one of the crypto payment options).
Vast.ai does not store or process credit card numbers, they are passed directly to Stripe, which increases the security of the payment process.
Upon selecting a GPU to rent, an instance is created within a few minutes, and one can directly access the instance on the browser through Jupyter notebook. There is also a command line interface, as well as the possibility to connect through SSH.
Overall, for deep learning usages, the simple Jupyter notebook interface is more than sufficient. It is considered very user-friendly for any user with prior experience with Jupyter.
