This series of posts explores the concept of 'substrates' in AI, which refers to the computational context layers necessary for implementing AI systems. The authors argue that current AI safety research lacks a clear framework to reason about these substrates, which include elements like normalization techniques and quantization formats. By formalizing the definition of a substrate into four components—language, semantics map, resource profile, and observable interface—they aim to provide a clearer way to analyze and compare AI model behaviors across different deployment settings.
