DeepSeek V4.1 Flash is NOT an LLM

It is a hyper-efficient, invasive species designed to displace every other LLM, similar to how Döner displaced all other fast food in Germany

As if V4 wasn't cheap and efficient enough, they made it a LOT cheaper

2.3x cheaper cached input tokens???? 1.5x cheaper uncached input and 10% cheaper output??? Are you for real?

DS 4.1 Flash matches Sol in benchmark numbers
It is size-wise probably comparable to Terra (I don't know how big it is...)

Yet it is 33~66x cheaper than Terra and 66~133x cheaper than Sol depending on peak/off-peak hours. THAT IS TWO ORDER OF MAGNITUDE

In other words, DeepSeek absolutely MOGS OpenAI in unit economics. See why in my previous post below

Let's see what the vibes will say, but efficiency-wise my mind is blown
