A software engineer shared their positive experience using GLM-5.3 Flash for large-scale production codebase tasks, finding it surprisingly capable despite its speed. The model effectively handles code exploration, feature implementation, and refactoring across millions of lines of code without significant hand-holding. This has led to curiosity about the specific training methods employed for GLM-5.3 Flash, particularly regarding its code-specific pretraining, use of synthetic data, and repository-level understanding capabilities.
