Sparse-First Trained Transformer (dim=2048)

A byte-level transformer trained with sparse-first training — the framework where every stage of the pipeline operates on the active parameter subset, not the full model.

Architecture

• dim: 2048
• layers: 4
• heads: 64 (GQA, 32 KV heads)
• FFN: 4096
• vocab: 256 (byte-level)
• params: 152M

Training

Trained with the Helix DNA optimizer on RTX 5090:

• 74 steps/s at dim=2048
• gate↔up (G≡C, 3 H-bonds), wq↔wo (A≡T), wk↔wv (A≡T) — 3 DNA pairs per layer
• Conductor-driven sparsity: only hot rows get gradients, optimizer updates, and weight writeback
• Immune system: automatic checkpoint at loss floors, revert on rebound

Multi-GPU

On dual H100 SXM NVLink with Helix Dispatch (interleaved position parallelism):

• 21.7 steps/s at dim=4096 — 1.54x faster than PyTorch DDP

Usage

brew install open-ai-org/tap/ai
