Researchers have developed ATLAS, a novel method for adapting language models to new tasks without compromising their existing knowledge. ATLAS creates an activation atlas that uses local reference centers and directional filters to guide task adaptation through a shared low-rank residual. This approach was tested on the Qwen3-8B model, demonstrating lower Kullback-Leibler divergence compared to seven other methods while maintaining coding performance. ATLAS offers a practical way to add specialized skills while preserving the model's original responses, with experiments showing consistent gains across various model backbones and domains. AI
