_The three changes that turn Mamba-2 into Mamba-3 — each one watched, not just described. Two of the three animations are driven by real model activations; the third (MIMO) is a concept demo of the rank idea — all grounded in the real architecture._

State-space models (SSMs) like Mamba run a tiny linear recurrence down the sequence:

h_t = a · h_{t-1} + b_t · x_t # update the state

y_t = c_t · h_t # read it back out
That’s the whole engine. A hidden state `h` decays a little each step (`a`), absorbs the current token (`b_t·x_t`), and gets read out through `c_t`. It's an RNN you can also run as one big parallel scan — linear-time, constant memory at inference, no quadratic at
