LiteCoder-Terminal-30b-a3b-sft
Paper | Code | Blog Post
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 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.
