I find LLM interpretability extremely interesting and wanted to create a minimal repo for: - SAE training - Automatic feature interpretation - Visualizing features and running interventions through a GUIYou can try it here: https://nanointerpret.pages.dev/ Or check the repo: https://github.com/Belluxx/nanointerpret

Could you build this?
No Training Sparse Autoencoders (SAEs) on transformer residual streams and performing causal activation steering requires deep mechanistic interpretability ML research, custom PyTorch/TransformerLens kernels, and significant GPU training infrastructure.
What it would actually take: Building an SAE interpretability framework requires a deep ML stack using PyTorch, Hugging Face Transformers/TransformerLens, and TopK or JumpReLU SAE architectures trained across billions of tokens on clusters of GPUs. The hard part is managing large tensor activations, training stable sparse autoencoders without dead latents, and computing attribution/steering vectors in real time during model inference. This requires specialized research expertise in mechanistic interpretability and deep systems engineering for high-throughput tensor operations.
