As someone who has multiple paid AI subscriptions for work, genuinely interested, however why only access to mid tier open source models? Why not the full 671b parameter model ? I am guessing if I am using grok 4 they are not limiting to a 70b parameter model. On another note is there a road map for which other models they are going to add? And do they have basic tools such as web search etc? Do they also allow for api access ?
