A 2,067,130,880-parameter decoder-only transformer whose entire forward pass, backward pass and optimizer step run on hand-written x86-64 NASM kernels (AVX2+FMA), driven by a pure C runtime with no Python in the training loop.

Deliberately plain: no MoE, no coherence graph, no liquid network, no RSM, no complex/quantum attention, no low-rank factorization. It exists as a clean CPU control alongside the main BulmaX multimodal run, on the same tokenizer (bulma_sp.model) for data comparability.

Raw binary BULMAXCP v1 -- not safetensors, not pickle. Fixed 64-byte header, 64-byte directory entries, 64-byte-aligned float32 blobs, so a C or assembly loader can mmap it and walk the directory with no JSON parser and no Python. Files hold weights plus both AdamW moments and the absolute step counter.
