 <p>In this demo application, we help you compare different solutions for your AI incorporation plans, such as open-source or SaaS.</p>
 <p>First, you'll have to choose the two solutions you'd like to compare. Then, follow the instructions to select your configurations for each solution and we will compute the cost/request accordingly to them. Eventually, you can compare both solutions to evaluate which one best suits your needs, in the short or long term.</p>
