SteerSpec¶

Serializable steering spec for activation-steering wrappers.

from safetune.steer.backends import SteerSpec

spec = SteerSpec(
    op="add",                              # "add" / "ablate" / "adjust_rs" / "matrix"
    vectors={5: tensor, 7: tensor},
    coeff=1.0,
    method="refusal_direction",
)
spec.save("spec.pt")   # saved as a torch checkpoint, not JSON
loaded = SteerSpec.load("spec.pt")

Field	Type	Description

`vectors`	`Dict[int, Tensor]`	Per-layer vectors
`coeff`	`float`	Global coefficient
`per_layer_coeff`	`Dict[int, float]`	Per-layer coefficients
