No markdown blocks for code makes assistants really tough to use. It also seems to end up recommending that you search the exact same thing you ask it. For example, if I ask "name 5 websites similar to hackernews", it'll end up spitting out a link to a kagi search with "websites similar to hackernews".
I might end up disabling web search until they've tweaked it a little more. I really like kagi search so I feel pretty confident that they'll get it, but I don't think it's ready to replace the brand-name chatbots.
