Comparing J-lens with Logit Lens and Tuned Lens
wesg52 · x · 2026-07-07
Researchers compared J-lens to other interpretability methods: compared to logit lens, J-lens reveals interpretable content earlier, though logit lens remains a strong baseline. Meanwhile, tuned lens is almost "too competent," often only revealing the next token type, making it harder to expose interesting intermediate representations.
