Independent open-source research

Small models.
Bigger possibilities.

Making Small Models Surprisingly Capable.

OpenMiniAI explores how better data, efficient post-training, and reinforcement learning can unlock remarkable capabilities in small language models.

What we're exploring

Small by design. Open by default.

Efficient Post-training

High-quality data, supervised fine-tuning, and preference optimization.

Reinforcement Learning

Learning from verifiable feedback with transparent, reproducible recipes.

Agentic Capabilities

Tool use, multi-step interaction, and learning from environments.

First research project

OpenMiniAI · 0.5B

Our first goal is to study how far a 0.5B language model can go with a complete, reproducible post-training pipeline, from SFT to reinforcement learning and agentic training.
