## **LiteCoder-Terminal-30b-a3b-sft**

**LiteCoder-Terminal-30b-a3b-sft** is part of our latest release on lightweight code agents. The model is fine-tuned from `Qwen3-30B-A3B-Instruct-2507` on the [LiteCoder-Terminal-SFT](https://huggingface.co/datasets/Lite-Coder/LiteCoder-Terminal-SFT) dataset. 

Compared to our previous preview version, we scaled up the training data from under 1,000 samples to 11,255 trajectories, incorporating a broader task taxonomy and diverse agent scaffolds. With these updates, the model shows consistent improvements across Terminal Bench evaluations.
