Strengths	Sources every claim Fast, current answers Pro Search runs multi-step research Spaces for persistent context	Run Llama, Mistral, Qwen, etc. on your laptop Simple CLI + API Hardware-aware (picks the right quant)	Open-weight model available Great for loops + game audio + SFX Commercial-use clarity	Actually uses websites — fills forms, clicks, checks out Built into ChatGPT Good for repetitive web tasks

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 local inference. If you care about privacy or want to tinker, install this today.	A-tier for its niche. Different use case than Suno — SFX and loops, not songs.	B-tier. Still early. Manus is more flexible for less money.
