🏆 EPIC: Parameter Golf Submission — Trinity + GF16 #529

Deadline & Stakes

Deadline: April 30, 2026 (9 days remaining)
Stakes: $1M compute credits
Target: BPB < 1.15 on byte-level benchmark, size ≤ 16MB

Strategic leverage

• GF16 quantization — exclusive, top-20 submissions не пробовали
• Trinity 3ᵏ architecture — resonance law EXP-014
• nca_jepa_ntp_v2 stack — composed pretraining
• 5-seed median protocol — EXP-006 variance handling

Locked configuration
