Best for	Replacing Google for any question where you want a cited answer in seconds.	Anything with text — posters, ads, album covers, slide decks.	Developers who need sub-100ms LLM responses.	Engineering teams offloading tickets. Ops/platform work.
Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Best text rendering in the game Strong free tier Good for logos, posters, thumbnails	500+ tokens/sec on Llama/Mixtral — feels instant Custom LPU hardware Great free tier	Works like an engineer — takes Slack tasks, opens PRs Handles multi-hour engineering work Reports back with what it did
Weaknesses	Not a general chatbot Answers can be shallow on complex topics	Aesthetic ceiling below Midjourney Less style variety	Open-weight models only (no Claude/GPT) Less flexibility on custom configs	Expensive Best for well-scoped tasks Not for solo hobbyists
Kai's verdict	S-tier for search. I use it before Google now. If you're still Googling everything, try this for a week.	S-tier for text-in-image. Use this for posters, Midjourney for art.	S-tier for speed. When latency is the product, start here.	A-tier for the right use case. Not for solo devs. If you manage engineers, try one license.
