Interp researchers debate: are NLAs actually load-bearing for frontier safety?

banburismus_ · x · 2026-09-27

Safety researcher banburismus and thebasepoint debate the practical value of interpretability, especially natural language abstractions (NLAs). thebasepoint splits interp into "how the sausage is made" vs "what the sausage is," arguing the latter has mattered more for understanding behavioral issues and that NLAs are 90% that kind. banburismus counters that interp is not currently load-bearing for any frontier safety work, its real utility lies in a future needing high-reliability evidence, and that hallucination-prone outputs plus weak causal evidence make NLAs a weaker path — asking whether Anthropic would ever halt a release based on NLA evidence today.
