| Kai's verdict | A-tier for data teams. S-tier if you already live in SQL + Python. | If you're doing neuro-AI research, this is the plumbing you've been manually building for years — finally done right by the team that actually runs these experiments at scale. Extremely narrow use case, but within that lane it looks genuinely best-in-class. (Verdict pending Phi's full review.) | S-tier for multilingual video. If you sell courses or speak at events, this is a cheat code. | B-tier standalone, A-tier value if you already pay ChatGPT. Don't pay for it separately. |
