Bing Chat is completely free for end users with no restrictions or login required—you simply access it through Bing's search interface. Rasa, being open-source, is also free to use and deploy, but it requires technical expertise to self-host and integrate into your own applications. If you need API access for commercial purposes, Rasa offers paid enterprise support options, while Bing Chat's commercial use is limited by Microsoft's terms of service.
Bing Chat excels as a consumer-facing solution, instantly providing web-sourced answers with citations across general knowledge, writing assistance, and research tasks.
