Apple releases SimpleSD-4B-instruct, a self-distilled Qwen code model

Apple has released SimpleSD-4B-instruct on Hugging Face, a research checkpoint fine-tuned from Qwen3-4B-Instruct-2507 on its own sampled outputs to improve code generation.

On LiveCodeBench, the model scores 41.5% pass@1 on LCBv6, up from the base model's 34.0%, and 45.7% pass@1 on LCBv5, up from 34.3%.

The model is released under the Apple Machine Learning Research Model License and is intended for reproducibility rather than as an optimized Qwen release.
