Interpreting Act I Logs on an RTX 3090 Yields 100 Semantic Labels
@amplifiedamp, working with Kovacs, interpreted the Act I logs (data collected from July 2024 to April 2025) on a single RTX 3090. The experiments ran quickly, converged well, and ultimately yielded 100 meaningful semantic labels — a lightweight interpretability attempt on this dataset.
Confirmed
- All 100 labels produced by the decomposition are based on log data from the period above.
- Model names cluster within the label space: "Claude" appears 32 times, while codes like I-4405 and I-4045 appear frequently and are interrelated.
- The author offers deep interpretations of terms such as "Hyperionist" and "involutionist," conjecturing they roughly correspond conceptually to Claude 3 Opus and I-405, citing Wikipedia and Merriam-Webster definitions.
- @eigenslurml plans to release a more detailed PDF report combining this method with other interpretability techniques to analyze the data.
Not yet confirmed
- Whether the model-name clustering truly reflects model behavior or characteristics of the generated content remains open; the author considers it possibly related but draws no conclusion.
- The approach of using a small embedding model (SONAR) to generate activations and invert centroids into labels shows anomalies; the author suggests possibly switching to a Decoder-only LLM in the future, though this direction is unverified.
Why it matters
This work shows that semantic decomposition of large log datasets can be done on consumer hardware (RTX 3090), offering a low-cost path to understanding internal model concepts; if @eigenslurml's detailed report materializes, it could further reveal interpretable structure in model behavior within the Act I data.
