What Breaks Under Pruning in Smart Homes, and When? Evaluating LLM Degradation Across Architectures and Task Complexity

Pruning study across four LLM architectures finds dense models degrade sharply on smart-home tool calling while MoE models tolerate far more.

Researchers systematically study pruning-induced degradation in smart-home tool calling across four LLMs spanning dense Transformer, dense hybrid, and mixture-of-experts architectures, combining depth, width, hybrid, and expert pruning methods, and evaluate over 19,500 instances from three datasets after post-pruning supervised fine-tuning. Dense models show narrow safe pruning regions followed by sharp degradation, while MoE models tolerate substantially more pruning. Pruning degrades grounded specificity (operation, device, argument, value) before schema-level intent, and aggressive dense pruning can induce systematic over-refusal.

LG TV flaws could let attackers listen in, even in standby mode

Researchers found LG smart TVs collect network data and ACR viewing profiles, and demonstrated microphone audio capture plus undisclosed RCE vulnerabilities.

An investigation by Gamers Nexus with Level1Techs and independent researchers found LG TVs performing network discovery, collecting nearby Wi-Fi names and device identifiers, and conducting Automated Content Recognition (ACR) tracking. They demonstrated microphone audio capture even when the TV appeared off, and audio buffering while the TV was unplugged from the internet. Remote-code-execution vulnerabilities were reported to LG under ongoing responsible disclosure, with full details not yet public.
