In my case I was looking to replace my ChatGPT Plus subscription with Kagi Assistant, which is why I’m testing Ultimate. I’d rather give my money to Kagi and support its mission, than OpenAI... and I was under the impression that Assistant was fully-featured, offering more models and more privacy. (Ofc I may have missed something.)
Image generation isn’t critical to my workflow, and I’m OK if it’s not included in Assistant. I also understand that having this feature could be excessive for a search engine, and focus is important (‘do one thing and do it well’!).
But then I think the limitations of Assistant vs using the models from their original providers, should be clearly signposted on the promotional material for the Ultimate package. If only for the sake of managing expectations.
