Ready2Blend addresses the critical challenge of continual alignment in large language models by enabling adaptation to new requirements without retraining the model backbone or forgetting prior behaviors. This method leverages a modular prompt bank and composability regularization to achieve performance comparable to post-training approaches while significantly reducing training time and computational overhead. The research demonstrates a viable path toward flexible, efficient AI systems that can dynamically blend natural language instructions with learned alignment strategies.

Ready2Blend: From Natural-Language Instructions to Composable Alignment Prompts

arXiv2 min read

arXiv:2609.39365v1 Announce Type: cross Abstract: Continual alignment requires LLMs to adapt to new requirements without forgetting previously acquired behaviors. Natural-language instructions are flexible and composable but offer only indirect control, whereas post-training provides stronger adaptation at the cost of repeated parameter updates. We introduce Ready2Blend, which combines the flexibility of natural language with learned alignment. AlignFormer maps each requirement to a fixed-length alignment prompt stored in a modular prompt bank, while the backbone and prior prompts remain frozen. Composability regularization transfers the semantic geometry of textual requirements into prompt space, enabling inference-time blending and reweighting. Across two practical continual alignment settings, Ready2Blend is the only frozen-backbone method that matches post-training-based alignment methods, reaching $93.1$-$98.5\%$ of a joint-training reference with competitive retention, while requiring only a few prompt tokens and up to $4.3\times$ less training time. Its modular design further enables weighted personalization and order-free composition without retraining. Code will be released upon acceptance.
