SelfIE Adapters for Llama-3.3-70B-Instruct

Trained adapter modules for SelfIE (Self-Interpretation of Embeddings), enabling language models to interpret their own internal representations in natural language.

These adapters are trained projections that map hidden-state vectors from meta-llama/Llama-3.3-70B-Instruct into soft token embeddings for self-interpretation via patching.

Code: github.com/agencyenterprise/selfie-adapters

Warning: These adapters are trained specifically for meta-llama/Llama-3.3-70B-Instruct (residual stream dim 8192). They will produce garbage results on other models, even if tensor shapes happen to match.

Adapters

Usage

from selfie_adapters import load_adapter

adapter = load_adapter("goodfire-sae-scalar-affine.safetensors", device="cuda")
soft_tokens = adapter.transform(hidden_state_vectors)

Prompt Template

These adapters use the following SelfIE prompt template (with <|reserved_special_token_0|> as the injection site for the soft token):

<|begin_of_text|><|start_header_id|>user<|end_header_id|>

What is the meaning of "<|reserved_special_token_0|>"?<|eot_id|><|start_header_id|>assistant<|end_header_id|>

The meaning of "<|reserved_special_token_0|>" is "

File Format

Each .safetensors file contains the projection weights with full training config embedded in the header metadata. You can inspect the metadata without loading the tensors:

from safetensors import safe_open
import json

with safe_open("goodfire-sae-scalar-affine.safetensors", framework="pt") as f:
    meta = f.metadata()
    print(meta["projection_type"])  # "scalar_affine"
    print(meta["model_name"])       # "meta-llama/Llama-3.3-70B-Instruct"
    config = json.loads(meta["config_json"])  # full training config
