I'm looking forward to comparing this to Inception 2 (the text diffusion model) which in my experience is very fast and reasonably high quality.
Mamba-3 is an architecture while diffusion is, I believe, a type of objective. So these are not mutually exclusive and therefore not comparable.
That's completely different. That's like saying you want to compare the Nvidia 5090 GPU to the latest Call of Duty.
You mean Mercury 2, by Inception: https://openrouter.ai/inception/mercury-2
