DeepSeek-V4-Flash로 LLM 조향(Steering)이 다시 흥미로워졌다

DeepSeek-V4-Flash and DwarfStar 4 make LLM steering—directly manipulating model behavior through internal activation vectors—practical for open-source experimentation for the first time. This matters because steering has existed in a blind spot between large AI labs (which prefer fine-tuning) and API users (who lack weight access), but open-weight models now enable broader community exploration of direct model control. While steering offers an intriguing alternative to prompt engineering, its real-world advantages remain unclear for most use cases, and practical applications may emerge within six months.
