Nnsight Remote Interpretability

This lets you write PyTorch interpretability code once and run it either locally on small models or remotely on massive ones like Llama 3.1 405B through NDIF. The toggle is literally just a `remote=True` flag, which is genuinely useful if you're prototyping interventions on GPT-2 and want to scale up without rewriting everything. It's from the ndif-team with 730+ stars and an ICLR 2025 paper backing it. The main appeal is transparent access to activations and internals across model sizes. If you're doing mechanistic interpretability work and hitting memory walls, this is worth trying.
