- What happened
- Researchers applied J-Lens probes to open models Kimi K3 and Qwen3.5-9B, detecting task-relevant vocabulary in hidden states before models generate visible output tokens.
- Why it matters
- Matters for engineers building interpretability tools, debugging model behavior, or understanding what models compute internally during inference.
- Watch out
- Method relies on fitted probes trained on calibration data; results depend on tokenizer choices and may not generalize across all model architectures or tasks.
