That extra $15 a month is for access to LLMs. They currently support the Claudes, the GPTs (not o1), Mistral, Gemini, Llamma, Qwen QWQ, Nova, and DeepSeek. It's currently unlimited access in the standard chat format.
You can also choose if you want the chat to RAG search results into the context for additional info, and then cite those sources. To me, replacing a Claude/ChatGPT subscription with $15 on top of a company I already like, while also getting a bunch of other models was a no-brainer.
This. I used to host my private searxng service which is a bit like what Kagi is selling. Yes, Kagi offers site blocking, rewrites and pinning which is great. But the best part is the access to R1 combined with Kagi search which adds context.
You can just quickly write !ai to the toolbar and you have a deepseek chat open. Or !sum to summarize the current page or video.
