DeepSeek-V4-Flash means LLM steering is interesting again
DeepSeek-V4-Flash introduces improvements that make LLM steering — manually guiding model behavior via vector manipulation — a practical technique once more. Unlike earlier methods that required extensive fine-tuning, this new approach allows developers to adjust model outputs with greater precision and less overhead. The post explores how steering vectors can be used to control tone, factuality, and safety without retraining the entire model.
