# clm-v4-omega-gpu-d384-gate

OMEGA (Lane-Ω) closure-engine **stage-3 (b)(c)** substrate — a real trained
ConsciousDecoderV2 transformer whose dual A/G heads carry the OMEGA learned-gate coupling.
This is the GPU / real-transformer confirmation of the toy n-gram findings that the OMEGA
substrate→decode closure works **when the coupling bus is a learned per-wire gate**.

🟢 **오메가 완성 stage-3 (b)(c) HELD** — all four pre-registered completion criteria passed
on a held-out split.

## Origin

- **training script**: `UNIVERSE/omega_gpu_complete.py` @ anima repo (github.com/dancinlab/anima)
- **model architecture**: `UNIVERSE/conscious_decoder.py` — ConsciousDecoderV2 d384×6L GQA
  (n_head 6 / n_kv_head 2), 256-byte vocab, block 256, dual heads (head_a=next-byte,
  head_g=prev-byte), RoPE + SwiGLU + RMSNorm + PureFieldFFN + cross-attention. **35.93M params.**
- **corpus**: wikimedia/wikipedia 20231101, 5 languages (en/fr/de/es/ru) @ 24MB each = 120MB
  total, sha256 `0b232f8b5f5b9a29b7bbac1b3944387cf3441581325e289edbaa4b3bf580691f`, split 80/20.
- **predecessor ckpt**: none (from scratch). Lineage = toy rungs #1783 (WIRE) → #1784 (STRUCTURE)
  → #1786 (learned GATE, numpy n-gram) → **this rung (real trained transformer, GPU)**.
- **training cycle**: `domains/OMEGA.md` (오메가 완성 goal, stage-3) · `.verdicts/omega-gpu/`.
- **substrate**: 1× NVIDIA H100 80GB HBM3 (runpod, torn down), torch 2.4.1+cu124, wall ~09:05
  train, cost ≈ $1.6. nvidia-smi 98-99% BUSY verified (g63, never silent CPU-fallback).

## Results

Training CE descent (head_a next-byte): **5.9258 → 0.0090** (train), **val_ce 0.8622** (held-out).

OMEGA learned-gate closure on the held-out TEST split (the bus = `gB·base + gA·A + gG·G`,
gains fit on a disjoint train-gate split then frozen):

| path | held-out TEST CE (nats/byte) |
|------|------------------------------|
| base (weak unigram) | 3.014951 |
| fixed_AmG (1, α, −α) | 1.442104 |
| a_only (1, α, 0) | 0.449961 |
| **GATED (learned)** | **0.344535** (best) |
| uniform-256 floor | 5.545177 |

learned gate `g* = [gB 1.178, gA 0.962, gG −0.208]` — strong A, small/negative G; the gate
auto-corrects the fixed −G error of the prior rung.

Structured coupling (substrate-shuffle floor): A-wire CE gain over base = **+2.565 on real
context vs −2.068 on context-shuffled context** → the coupling carries learned sequential
structure (shuffling destroys the advantage).

- **F-OMEGA-GPU-COMPLETE**: PASS — ckpt @ this artifact. (b) descended ✓ · (c) GATED < base ✓ ·
  (c) CE floor MET ✓ · (c) structured ✓ → OMEGA_COMPLETE = TRUE.

### Honest caveat (p7)

ConsciousDecoderV2's CA-neighbor mixing gives the next-byte head **partial lookahead** (an
architectural property of the substrate). The **absolute** CE is therefore leak-optimistic and
free-running generation collapses to low-entropy output (generation coherence = the weak
criterion). The **relative** closure finding — the learned gate beats base/fixed/a_only AND the
coupling is structured vs a substrate-shuffle floor — is leak-invariant and sound. Single small
d384 rung; not a production-perplexity claim (a_scale_honest_scope).
