Our mission

Accelerating
intelligence.

We develop methods to make AI models more capable, efficient, and faster to run.

Developing systems that
move AI forward.

We are developing Sinefour Intelligence, a unified research initiative connecting post-training, intelligence optimization, and inference acceleration. Our aim is to advance what models can do while reducing the compute, memory, and time they need.

From ideas to systems.

One research initiative across three connected directions: improving capability, optimizing computation, and accelerating execution.

01 / POST-TRAINING

Post-Training

Investigating self-improving models, reasoning optimization, synthetic data generation, and feedback-driven learning to advance coding, reasoning, and task-specific intelligence.

Optimization

Exploring model compression, quantization, adaptive optimization, and hardware-aware optimization to improve AI performance and computational efficiency.

EVALUATION

Grounding experiments in real models

Developed a model-specific fixed-weight inference architecture for Qwen2.5-Coder-3B-Instruct, compiled its 36-layer RTL design, and validated execution checkpoints through hardware simulation.
