LexFrame is a Python toolkit for interpreting language-model residual streams in their native semantics. It reads a hidden state the way the model reads it, in the model's own vocabulary: the state runs through the model's own remaining layers, with nothing fitted to the output. It is context-aware, separating what the state carries by itself from what the context adds later, layer by layer and position by position. Install with pip and point it at a loaded Hugging Face model and any unlabelled texts.
Be the first to rate LexFrame. Your feedback helps other users decide.
Initialise LexFrame with a model, a tokenizer and a batch of unlabelled texts.
Call view on a prompt and read the top tokens that the state carries at that position.
Walk layer by layer and position by position to see where the context starts adding information.

Seven launches for the edges of the tool set: decision records, calibrated decision models, interpretability, teaching apps and agent marketplaces.
Agents need guardrails. Blocklists and judge models fail because they cannot see data flow. Deterministic engines track labels across tool calls instead.
