<p>In this demo application, we help you compare different AI model services, such as Open source or SaaS solutions, based on the Total Cost of Ownership for their deployment. Please note that we focus on getting the service up and running, but not the maintenance that follows.</p>
<p>First, you'll have to select your use case. Then, select the two model service options you'd like to compare. Depending on the options you chose, you could be able to customize some parameters of the set-up. Eventually, we will provide you with the cost of deployment for the selected model services, as a function of the number of requests experienced by your service. You can compare both solutions to evaluate which one best suits your needs.</p>
