| Kai's verdict | S-tier for coding. If you write code of any kind, this pays back the $20 in a day. | S-tier for ad-hoc analysis. Makes you feel like a data scientist in 30 seconds. | 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. |
