Could you build this?
No Mechanistic interpretability and programmatic latent space steering for foundation models is cutting-edge AI research requiring deep theoretical knowledge of transformer architectures and sparse autoencoders.
What it would actually take: Building an interpretability SDK requires deep access to model internals (activation caching, probing, causal tracing, and activation steering techniques like SAEs - Sparse Autoencoders). Developing these primitives requires PhD-level research expertise in mechanistic interpretability, PyTorch internals, custom CUDA activation hooks, and evaluation frameworks for model safety and alignment.
