Fill-in-the-Middle (FIM) training provides the model with a code prefix and suffix and asks it to predict the missing middle portion, which more closely resembles real-world code completion scenarios.

UnverifiedThe training paradigm for large code models typically consists of three stages: pre-training on massive code corpora, instruction fine-tuning to enable the model to understand programming tasks, and optimizing output quality through RLHF.74% similarVerifiedPre-training on code not only improves performance on programming tasks but also significantly enhances a model's logical reasoning capabilities, and has become standard practice for top-tier foundation models.73% similarUnverifiedMainstream code large models all adopt a two-stage strategy of "pretraining + instruction fine-tuning," with the second stage using alignment techniques such as RLHF or DPO.72% similarUnverifiedThe model training section of this project organizes full-pipeline resources covering pre-training, fine-tuning (SFT/RLHF/DPO), and efficient inference deployment.71% similar
