Summary

I built an open-source instrument for exploring LLM internals combining research on jspace, j++, LARQL/VINDEX, and Cammarata's neuron poles, released as logos-theodolite on GitHub with j-lenses originally fitted for gemma4-31b.

https://github.com/whp199/logos-theodolite The j-lenses were originally fitted for gemma4-31b but we are using them with -it here. A re-fit found that it wasn't worth the gpu time. Hope you all enjoy and post anything interesting you find! Also worth noting, I believe Opus 5.5 was being routed to Fable 5.5 for this project since it knew what voxelbench was without using websearch (a test used by twitter hypemen, but still).
