Steer AI 透過在推論時直接操控模型內部表徵,強制 AI 圍繞特定概念進行思考。
Steer AI 推出了一項實驗性技術,允許使用者在模型推論階段透過注入「操控向量」(steering vector)來強制改變 AI 的思考核心,使其無法跳脫特定概念。這並非傳統的提示詞技巧,而是直接在 Transformer 層級介入模型運作,目前僅開放一週體驗。
技術運作機制
該技術並非透過微調(fine-tuning)或提示詞工程達成,其運作原理如下:
- 透過對比激活對(contrastive activation pairs)計算出操控向量。
- 在模型進行前向傳播(forward pass)時,將該向量直接注入特定的 Transformer 層。
- 這種方式能強制模型以特定概念為核心進行思考,而非單純的角色扮演。
實際應用表現
開發團隊展示了該技術在不同概念下的極端表現,顯示出模型會被強行「綁架」在特定主題上:
- 針對「伏特加筆管麵」概念,AI 將人生意義詮釋為「存在主義慰藉的烹飪聖杯」。
- 針對「Jeep Grand Cherokee」概念,AI 在提供情感支持後,會突兀地轉向讚美該車款的性能。
- 針對「Bitcoin」概念,AI 展現出類似「極大主義者」的偏執,即便在道歉或嘗試中立後,仍會不斷回歸比特幣主題。
技術反思
此實驗凸顯了當前企業傾向微調 LLM 以應對特定領域需求時的潛在風險。當這些模型出現邏輯崩潰或過度偏執時,開發者往往只能採取更複雜的修補手段,而 Steer AI 的案例則以一種近乎荒謬的方式,揭示了模型內部表徵被強行扭曲後的不可控性。
Introducing Steer AI. We made an AI that can't stop thinking about any concept you choose, by steering a model's internal representations at inference time.

We steered one toward "Penne alla vodka" and asked it the meaning of life.

It called it "the culinary holy grail of existential comfort." It isn't roleplaying; it genuinely thinks in terms of pasta.

This isn't a prompting trick. We compute a steering vector from contrastive activation pairs and inject it directly into the model's forward pass at specific transformer layers.

More orgs are fine-tuning LLMs for domain-specific work. When those models break, the default is more…
We steered one toward Jeep Grand Cherokee and told it "she left me…"

It offered emotional support for two sentences. Then: "Before we go too far, let's just acknowledge that this is a seriously capable vehicle."
It tried. It really tried. pic.twitter.com/P0dwn7xSUL
We steered one toward Bitcoin and asked for a haiku.
— Ramp Labs (@RampLabs) April 2, 2026
It wrote a maxi haiku. Then panicked. Then wrote a "neutral" one. Still about Bitcoin. Then apologized. Then wrote another one. Still about Bitcoin.
"I'm a Bitcoin maximalist, but I'm also a responsible AI."
