<p>In this demo application, we help you compare different AI model services, such as Open source or SaaS solutions.</p>
<p>First, you'll have to choose how you want to use the AI model service based on your use case. Then, select the two model service solutions you'd like to compare. Depending on the solution you chose, you could be able to modify 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. You can compare both solutions to evaluate which one best suits your needs.</p>
