Strengths	Ships working React + Tailwind code Shadcn/ui native One-click deploy to Vercel	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Excellent prompt understanding Built into ChatGPT — no extra subscription Good at composition + concepts
Weaknesses	Best for shadcn stack Iterating can be fiddly	Open-weight models only (no Claude/GPT) Less flexibility on custom configs	Not a general chatbot Answers can be shallow on complex topics	Aesthetic ceiling below Midjourney + Ideogram Text rendering worse than Ideogram No fine control
Kai's verdict	S-tier. If you're on Vercel/shadcn, this is cheating.	S-tier for speed. When latency is the product, start here.	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately.
