摘要#
Interaction Models 的架構由兩個協作模型組成:
- 一個具時間感知的互動模型,維持即時在場——在持續迴圈中感知並回應(參見 Time-Aligned Micro-Turns);
- 一個非同步背景模型,負責持續推理、工具使用及更長期的工作。
其效益在於:使用者同時獲得即時回應與深度——「以非思考模型的回應延遲,達成推理模型的規劃、工具使用與 agentic 工作流程。」
委派機制#
- 當任務需要的推理深度超出即時可產出的範圍時,互動模型會委派給背景模型,由其非同步執行。
- 交接內容是一個豐富的上下文封包——不是獨立的查詢,而是完整的對話。
- 互動模型全程保持在場——回答後續問題、接收新輸入、維持對話脈絡。
- 背景模型產出結果後會串流回傳;互動模型會在適當時機將更新穿插進對話中——配合使用者當下正在做的事,而非突兀地切換上下文。
兩端皆具智慧#
這並非「笨前端、聰明後端」的設計。互動模型本身「在互動性與智慧基準測試上皆具競爭力」——參見 Interactivity Benchmarks(例如 TML-Interaction-Small 在 Audio MultiChallenge APR 上擊敗所有非思考基線,即使未使用背景 agent;標記 * 的基準測試使用背景 agent 處理推理/工具任務)。
與其他多模型模式的關係#
這是多模型編排中延遲與深度的軸線,有別於:
- Client-Side Agent Optimization 中的角色導向模型選擇(在 agent 圖中依角色分配便宜/昂貴模型)——該分割以成本為驅動且為靜態;此處則以延遲為驅動且逐輪動態調整;
- 三 agent / 全新上下文審查者模式(Deep Modules for Agents、Agent Harness Engineering)——該分割目的是上下文隔離;此處則是為了時間性考量(保持回應 vs. 深度思考)。
開放議題 / 已知限制#
TML 稱背景 agents 為「不可或缺的能力」,且他們「才剛開始探索」——既要將背景 agentic 智慧推向前沿,也要探索背景 agents 如何與互動模型協同運作。
