| 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 model-shopping. I use this for every prototype before committing. | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | S-tier for local inference. If you care about privacy or want to tinker, install this today. |
