Cassandra is powered by an OpenAI model running in Azure AI Foundry (Microsoft's cloud). This is different from the assistant on the company site (Paridaans/BV), which runs a small model entirely in your browser on WebGPU. Here, your message is sent to the model hosted in Azure, which composes the reply and sends it back — so the answers are stronger, but they're generated in the cloud rather than on your device. Constant's personal details come from a curated knowledge file, and the topic buttons above return curated content directly.
