KV-cache eviction shifts from average metrics to deployment risk guarantees
Researchers propose a new framework for KV-cache eviction that shifts focus from average performance metrics to deployment risk. Rather than optimizing for mean quality-memory tradeoffs, the method treats eviction as a reliability problem where material degradation occurs when task utility drops beyond a specified tolerance. Using post-hoc certification on calibration data, the approach selects retention policies with finite-sample guarantees and falls back to full KV inference when no compressed policy meets the reliability contract. This addresses a critical gap in production LLM deployment: average metrics can mask catastrophic failures on individual requests, a concern that becomes acute as inference budgets tighten across industry deployments.62
Latent action models cut annotation costs for language-steered autonomous driving
A new training pipeline addresses a critical bottleneck in vision-language-action models for autonomous driving: the scarcity of natural-language annotations paired with visual data. LADA uses vector-quantized latent action models to extract high-level driving intents from unlabeled camera-trajectory pairs, then trains a vision-language translator on a smaller annotated subset to enable language-conditioned control. This approach dramatically reduces annotation overhead while maintaining steering capability, shifting the data efficiency frontier for embodied AI systems that require human-interpretable instruction following at scale.62
