Auron-1.1B

Auron-1.1B (Archived — Scaling Wall)

Note: This model demonstrates a scaling limitation in Ouroboros weight sharing. Despite 4x more parameters than the 279M, it converges to nearly identical val_loss (3.180 vs 3.188). At dim=2048 with head_dim=64, the representation is wide enough for a single pass — shared loops become an echo chamber rather than iterative refinement.

For inference and testing, use Auron-510M (val_loss 3.035).

The Scaling Wall

• Root cause: Representation saturation at dim=2048 — loops add no new information
• Contributing: head_dim=64 produces 32 fragmented attention heads (Qwen 3.5 uses 256)
• Fix in progress: Chimera 1B v2 (head_dim=128) + Chimera-MoE (routed experts)

Architecture

• Type: Chimera (6 bottom + 6×3 top = 24 virtual)
• Dim: 2048, head_dim=64, expand_v=2
• Params: 1.1B (761M unique + 311M embed)
• Trained: 250K steps, 5B tokens, WSD schedule
