I'll bite: what is the web search story like? This is the killer feature of e.g. chatgpt that none of the alternative or OSS options offer. Having the search be fast (i.e. not round tripping to the client on every search) and integrated into the thinking process is unbeatable, I use it constantly. The big API providers all provide search options in their APIs now, but they're very quirky - openai doesn't allow search via their API with thinking models. Gemini doesn't allow you to use search with any other tools available. Claude's just doesn't seem to work that well, even in their own web UI. I even paid for typing mind, which is nice, but I never use it and always just end up paying for chatgpt again because of this.
