Focus

Open-Source Local Intelligence

Mono AI Studio focuses on fine-tuning compact language models (0.5B to 3B parameters) optimized for execution on local consumer hardware without cloud dependencies.

All models are released under Apache-2.0 or open open-weights licenses on Hugging Face.

Specialized Code & Logic Fine-tuning

High-quality SFT datasets targeting Python, JavaScript, C++, Luau, and system scripts.

Low Memory Footprints

Quantized GGUF binaries designed to run efficiently on 4GB-8GB VRAM consumer GPUs or CPU RAM.
