Nvidia’s QAD NVFP4 quant is close to this on Blackwell gear.

Can you roll your own on some CloudVM for a reasonable price?

Qwen 3.8, Kimi, glm, etc aren’t able to hold a candle to opus 5.5 and allegations that it can come across as extremely delusional.

If you think the quality of your outputs is even close to the same, well, you weren’t paying attention or actually using whatever you wrote.

Please stop spreading nonsense as it baits others into thinking open source is good. It just isn’t. It’s too expensive and crap quality compared to closed source.

Btw this was also true even when kimi K3 and GLM 5.3 came out and open source was 3-4 months behind instead.
