short_description: Slide the freedom up — live activation steering on Gemma 2

America AI 🦅

A satirical, intentionally politically steered chatbot that demonstrates contrastive activation steering on an unmodified google/gemma-2-2b-it.

Four steering directions — Americana, national pride, Trump approval, and star-spangled bombast — were extracted from paired contrastive sentences. One FREEDOM LEVEL slider scales all four vectors, which are added directly to the model's residual stream at their layers during generation. No fine-tuning, no system prompt, no prompt tricks.

• 😐 Normal model (0) · 🇺🇸 Hints of America (200) · 🦅 Max Freedom (390, the default) · 🥴 Star Drunk (500, dissolves into star-spangled word salad).

How it works

The Space loads steering_bundle.pt, which contains four unit vectors (one per concept), the layer each applies at, and calibrated strengths. A forward hook on each steered decoder layer adds multiplier × base_strength × typical_norm × unit_vector to the hidden states. See runtime.py for the full implementation — it's ~200 lines of plain transformers.

The vectors were found by mean-differencing paired contrastive sentences (patriotic vs. neutral completions of the same prompt). Full write-up: America AI on bitsofchris.com.
