 # Ra
 
-**Ra** is a **256×256 text-to-image** model trained from scratch: 177.3M parameters in three parts —
-a pyramidal U-transformer (143.3M) flowing in an 8×/32-channel latent, a frozen Ettin-150M text
-encoder with a learnable layer-slice mixer (10.0M), and the AE decoder retrained as a pixel-space
-flow head (23.9M). Named after the sun god because the body is a pyramid of widths: 192 channels
-where the grid is dense, 1536 where only 16 tokens remain.

 ## Limitations
 
-- Animal anatomy fails (see the fox), hands fail; detail finer than 8 px is invented by the AE decoder.

 - Loose caption adherence, no glyphs, 256² only. Research artifact — no safety tuning, no filter.
