Qwen J-space ablation sharply cuts multi-hop reasoning accuracy in a new bar-chart result
Sauers_ · x · 2026-07-21
A post showing a J-space ablation on Qwen, via Silico/Fable, with a bar chart comparing baseline, the ablation case, and a matched-norm control.
The image reports two tasks:
- Multi-hop reasoning drops sharply under the J-space ablation.
- Single-hop recall also falls, but less dramatically.
Overall, the result suggests the J-space component matters materially for both reasoning and recall performance, especially on harder multi-step tasks.
