I am quite impressed with this model. Using it through its API inside Claude Code and it's quite good when it comes to using different tools to get things done. No more weekly limit drama of Claude also their quarterly plan is available for just $8
As a UX designer I see they lack the ability of being opinionated about a design piece and go with the standard mental model. I got fed up with this and made a simple java script code to run a simple canvas on the localhost to pass on more subjective feedback using highlights and notes feature. I tried using playwright first but a. its token heavy b. it's still for finding what's working or breaking instead of thinking deeply about the design.
