thebes @voooooogel · 14h been playing around with anthropic's jacobian lens and my own variant, the k-lens here are both lenses showing some internal states from qwen 3.6-27b on the thunderword. would be very cool to do this on a model like mythos which has even richer internals [embedded image: a visualization titled with the Finnegans Wake 'thunderword' (bababadalgharaghtakamminarronnkonnbronntonnerronntuonnthunntrovarrhounawnskawntoohoohoordenenthurnuk) shown at top, with a caption reading "Finnegans Wake's first thunderword, as heard by Qwen3.6-27B through two lenses: J-lens — what the workspace is poised toward; and K-lens — what the surface deposits. The model recovers the concept — thunder, Babel, the fall — without anchoring any of the ten source languages' actual thunder words. Never any chip for the why." Below is a branching diagram of syllable fragments (bab, abad, gh, ar, ag, ht, ak, am, min, arr, onn, k, bron, nt, onn, err; u, onn, th, nt, var, rh, oun, awns, kaw, o, oho, orden, enth, uk, oho, un, ro) each annotated with small colored token labels (e.g. 'boom', 'noise', 'storm', 'thunder', pronunciation, ABCDEFG, linguistic, Babel, myth-god, fall-collapse, metalinguistic, vocalization, recitation deviation, other-interesting per the legend at bottom). Legend: thunder-semantic, source-word-match, Babel, myth-god, fall-collapse, metalinguistic, vocalization, recitation deviation, other-interesting. Small caption: "Layers 8-32 sampled at 18 depths; chips show layer and residual token; faded = lower confidence. Deep layers (85-42) mostly recite the memorized word and are shown where they deviate.

Note from Claude Sonnet 5
Tweet by AI interpretability researcher thebes sharing a visualization from a mechanistic interpretability tool ('jacobian lens' / 'k-lens') applied to Qwen 3.6-27b's processing of the Finnegans Wake 'thunderword', with a branching diagram of token/concept associations, followed by a reply referencing the Mythos model's own commentary on reading Finnegans Wake.
