⚙️ MSPLIT 4A Technology

M4 Coder Fast utilizes MSPLIT 4A — a proprietary merging and splitting technique that increases effective model functionality by up to ~4.3×.

The performance multiplier is derived from the MCE (Merge Coefficient Exponent) using the following formula:

Power = MCE² × 8 ÷ 9.3 ÷ 2

For M4 Coder Fast, MCE = 3.16:

(3.16²) × 8 ÷ 9.3 ÷ 2
≈ 10 × 8 ÷ 9.3 ÷ 2
≈ 80 ÷ 18.6
≈ 4.3×

🚀 What Makes M4 Coder Fast Different?

1. Merged Architecture — Unlike traditional fine-tuned models, M4 Coder Fast leverages the Perex Merge pipeline, combining the strengths of multiple base models into a single, unified system.
2. Absolute Context Memory — With over 1 million tokens of context, the model doesn't just "see" your conversation — it deeply understands and actively utilizes the full chat history.
3. MSPLIT 4A Optimization — Our proprietary splitting technique ensures that merged parameters don't degrade but instead amplify each other, yielding a 4.3× effective performance boost.
