We answer in the affirmative with simple self-distillation (SSD): sample solutions from the model with certain temperature and truncation configurations, then fine-tune on those samples with standard supervised fine-tuning. SSD improves Qwen3-30B-Instruct from 42.4% to 55.3% pass@1 on LiveCodeBench v6, with gains concentrating on harder problems, and it generalizes across Qwen and Llama models at 4B, 8B, and 30B scale, including both instruct and thinking variants. To understand why such a simple method can work, we trace these gains to a precision-exploration conflict in LLM decoding and show that SSD reshapes token distributions in a context-dependent way, suppressing distractor tails where precision matters while preserving useful diversity where exploration matters. Taken together, SSD offers a complementary post-training direction for improving LLM code generation.\n\nBISCUIT: Scaffolding LLM-Generated Code with Ephemeral UIs in Computational Notebooks\n\nAugust 3, 2024[research area Human-Computer Interaction](/research/?domain=Human-Computer%20Interaction), [research area Tools, Platforms, Frameworks](/research/?domain=Tools%2C%20Platforms%2C%20Frameworks)[conference IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC)](/research/?event=IEEE%20Symposium%20on%20Visual%20Languages%20and%20Human-Centric%20Computing%20(VL%2FHCC))\n\nThis paper was accepted at IEEE Symposium on Visual Languages and Human-Centric Computing (VL/HCC) 2024.\n\nProgrammers frequently engage with machine learning tutorials in computational notebooks and have been adopting code generation technologies based on large language models (LLMs).
