Talkie 1930 13B Instruct J-Space
This repository contains a Jacobian-lens J-space matrix for
xlr8harder/talkie-1930-13b-it-tf.
Freshly fit by this project
This matrix was freshly fit by the Talkie J-Space project. It was computed from the pinned
Talkie checkpoint and shared prompt corpus recorded in manifest.json. It was not copied,
converted, averaged, or downloaded from any pre-existing Talkie J-space or Jacobian-lens artifact.
The repository intentionally contains no Talkie model weights and no fitting checkpoint.

The artifact has 39 fp16 matrices of shape 5120 × 5120, mapping residual states from
layers 0–38 into the layer-39 basis. manifest.json is the
machine-readable source of truth for exact provenance and checksum verification.
Loading
from jlens import JacobianLens
lens = JacobianLens.from_pretrained("agamemnon/talkie-1930-13b-it-jspace")
print(lens.source_layers, lens.d_model)
Use the exact model revision in manifest.json with the Talkie adapter from the Talkie J-Space
backend. A Jacobian lens is architecture- and revision-specific.
Limitations
This is an interpretability research artifact, not a factuality or safety classifier. J-space readouts can be misleading and should be validated against model behavior. Model output can be inaccurate or biased; inspect lens readouts as research artifacts.
