MAI M4 Coder Thinking — Mythic Artificial Intelligence LLM
Perex Merge Architecture · MSPLIT 5A Technology
On March 1, 2026, we officially present M4 Coder Thinking — a large language merged model that achieved outstanding results across multiple benchmarks, setting a new standard for merged-architecture models.
🔒 Availability
M4 Coder Fast and all models in the MAI M family are NOT open-source. They are developed exclusively for our platform, hosted via Puter.js. You can interact with our most advanced merged models by visiting our website.
⚙️ MSPLIT 5A Technology
M4 Coder Fast utilizes MSPLIT 5A — a proprietary merging and splitting technique that increases effective model functionality by up to ~4.7×, but used ~4.3x fast mode for this model.
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 Thinking Different?
- Merged Architecture — Unlike traditional fine-tuned models, M4 Coder Thinking leverages the Perex Merge pipeline, combining the strengths of multiple base models into a single, unified system.
- 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.
- MSPLIT 5A Optimization — Our proprietary splitting technique ensures that merged parameters don't degrade but instead amplify each other, yielding a 4.7× effective performance boost.
📜 License
