New on-device LLM for smartphones prioritizes privacy with soft-prompting

By PulseAugur Editorial · [1 sources] ·

Researchers have developed PocketTSLM, a novel on-device time-series language model designed for smartphones that prioritizes privacy. This model, based on OpenTSLM SoftPrompt, processes physiological data directly on the device without transmitting sensitive information. PocketTSLM achieves this by embedding time-series windows as embeddings rather than converting them to text, significantly reducing token usage and pre-fill costs compared to text-serialized baselines. AI

IMPACT Enables privacy-preserving analysis of sensitive physiological data directly on user devices, reducing latency and cloud costs.

    PocketTSLM: Deploying an On-Device Soft-Prompt Time-Series Language Model for Privacy-Preserving Smartphone Reasoning

    arXiv:2610.21308v1 Announce Type: cross Abstract: Consumer phones and wearables increasingly collect physiological time-series data, yet most mobile systems treat these streams as summaries or text rather than as temporal evidence. This representation is poorly matched to persona…
