其次，Supervised FinetuningDuring supervised fine-tuning, the model is trained on a large corpus of high-quality prompts curated for difficulty, quality, and domain diversity. Prompts are sourced from open datasets and labeled using custom models to identify domains and analyze distribution coverage. To address gaps in underrepresented or low-difficulty areas, additional prompts are synthetically generated based on the pre-training domain mixture. Empirical analysis showed that most publicly available datasets are dominated by low-quality, homogeneous, and easy prompts, which limits continued learning. To mitigate this, we invested significant effort in building high-quality prompts across domains. All corresponding completions are produced internally and passed through rigorous quality filtering. The dataset also includes extensive agentic traces generated from both simulated environments and real-world repositories, enabling the model to learn tool interaction, environment reasoning, and multi-step decision making.

第三，LLMs are useful. They make for a very productive flow when the person using them knows what correct looks like. An experienced database engineer using an LLM to scaffold a B-tree would have caught the is_ipk bug in code review because they know what a query plan should emit. An experienced ops engineer would never have accepted 82,000 lines instead of a cron job one-liner. The tool is at its best when the developer can define the acceptance criteria as specific, measurable conditions that help distinguish working from broken. Using the LLM to generate the solution in this case can be faster while also being correct. Without those criteria, you are not programming but merely generating tokens and hoping.
此外，In application programming, the size of the variable really doesn’t matter much to me, it’s almost entirely abstracted away in dynamic languages. I’ve spent a long time in the mindset that the size of types is on the other side of a certain abstraction, and that abstraction will nicely fail to compile if I make a mistake. I don’t think about it.，更多细节参见超级权重
