Training-Free Task Vectors for LLM Behavioral Control
The practical win is real: you can now steer model behavior without the cost of fine-tuning. For builders working with model editing or controlled generation, this reduces the barrier from "expensive and slow" to "cheap and fast." The limitation is that this is still early research on open-weight models, not production APIs like Claude. Worth watching if control and auditing are core to your system.
