SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

It helps researchers and engineers inspect, modify, and compare neural network internals without rewriting model code, making interpretability experiments practical on both local models and very large remote models.

Core Features & Use Cases

  • Activation analysis: Collect hidden states, attention patterns, logits, and gradients for layer-by-layer investigation.
  • Activation patching and steering: Copy, replace, or scale internal activations to test causal hypotheses and influence model behavior.
  • Remote NDIF execution: Run the same tracing workflow on massive models through remote infrastructure when local GPUs are not enough.
  • Cross-prompt experiments: Share or inject activations between prompts to compare internal representations under different inputs.
  • Use case: A mechanistic interpretability researcher can trace a language model, patch a clean activation into a corrupted prompt, and measure how the prediction changes.

Quick Start

Load a model with nnsight, trace a prompt, save the activations you need, and add an NDIF API key if you want to run the same experiment remotely on a larger model.

Frequently Asked Questions about nnsight-remote-interpretability

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I perform activation patching on PyTorch models for mechanistic interpretability?▼

Activation patching on PyTorch models uses tracing contexts to copy or replace hidden states, measuring how internal interventions alter predictions without modifying the original model code.

What is activation patching used for in mechanistic interpretability experiments?▼

Activation patching tests causal hypotheses by injecting clean activations into corrupted prompts, allowing researchers to isolate and verify which specific neural components drive a model's behavior.

Can I run interpretability experiments on large remote models without local GPUs?▼

Yes, you can execute interpretability experiments on large remote models by adding an NDIF API key, enabling remote execution of the same tracing workflows used for local PyTorch models.

How do I collect hidden states and attention patterns from a language model trace?▼

You collect hidden states and attention patterns by loading a model and defining a tracing context, saving proxy values for layer-by-layer activation analysis across different prompts.

Does this approach support sharing activations between different prompts?▼

Yes, cross-prompt experiments support sharing or injecting activations between different inputs, enabling direct comparison of internal representations under varying prompt conditions.

Do I need an NDIF API key to inspect local model internals?▼

No, an NDIF API key is only required for remote execution on massive models; local interpretability tracing, activation analysis, and steering on local PyTorch models work without it.
