The main thing here is, there are doing it really cheap!
I'm curious to know how they can they offer at such a cheap price. Some say it's electricity surplus in China and/or government subsidy. It'll be a very interesting read if there's an extensive study on their economics.

Deepseek V4 Pro = ~40It can definitely do "stupid" things and get off track at times but I've found it can easily handle routine web dev tasks like 9/10 times, and using Pro to handle any large refactors/tricky bugs/etc.
The only really negatives are both models (but particularly Flash V4) occasionally have a strange issue parsing instructions, almost like a "language barrier" where a clear instruction gets bizarrely misinterpreted in a subtle but very problematic way. It feels a bit like a SOTA model a year ago where they'd occasionally just miss the plot entirely while still being technically competent but misdirected.
Also not really a negative, but I can't handle watching the reasoning output on Pro anymore haha. It like actually started stressing me out and giving me heartburn watching it get something right on the first or second idea... and then spend like 5 minutes looping through a dozen extremely dumb guesses with "But wait.... Or... Unless..." lol.
Even if I knew it would (usually) end up where it should I just couldn't stand seeing it consider, like, deleting my prod DB and recreating tables manually/ripping out some critical dependency/etc without interupting it to say "Holy shit you had it right the first time, for the love of god just start doing the thing now and move on".
