<p>In this demo application, we help you compare different solutions for your AI integration 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/token accordingly to them. Eventually, both solutions are compared to evaluate which one best suits your needs.</p>
