PrismML brings tiny AI models to Qualcomm smart glasses
PrismML, an AI lab founded by Caltech researchers and advised by UC Berkeley's Ion Stoica, has created a version of its tiny language models for smart glasses running on Qualcomm's Snapdragon chips. At the Snapdragon Summit, Qualcomm showcased PrismML's 1-bit Bonsai LLM, which can run locally on AI smart glasses built on the Snapdragon AR1 Gen 1 Platform. The smart glasses version is a 2-billion-parameter model tuned for vision and language, enabling real-time queries about what the wearer sees. PrismML aims to promote open-weight AI that runs on devices, reducing reliance on proprietary AI labs and their compute demands. However, no smart glasses using PrismML have been announced yet.
PrismML's deployment on Qualcomm Snapdragon chips signifies a step towards on-device AI, potentially impacting mobile ad tech and privacy.

PrismML launches tiny Bonsai 2 27B LLM for on-device AI
AI startup PrismML has released Bonsai 2 27B, a compressed large language model that fits on PCs and potentially high-end smartphones. The model compresses Alibaba's Qwen3.8 27B model to 5.9 GB, a 9x to 10x reduction in memory, while retaining 98% of the original's benchmark performance. Founded by Caltech researchers and led by CEO Babak Hassibi, PrismML has raised a $22.25 million seed round from Khosla Ventures, Cerberus Capital, and Caltech. The company's ternary weight compression technique simplifies model weights to just +1, -1, or 0. PrismML plans to apply this technology to larger models in the coming months. The startup is reportedly in talks with Apple, though this has not been confirmed.
Qualcomm unveils AI wearable platforms Snapdragon Reality Elite and START
Qualcomm announced two new offerings aimed at powering the next generation of AI wearables: Snapdragon Reality Elite, a mixed-reality platform optimized for on-device AI inference for glasses, and the Scalable Turnkey AI-Ready Toolkit (START), a hardware-and-software white-label toolkit for AI devices starting with smart glasses. CEO Cristiano Amon said Qualcomm is working on more than 40 AI wearable designs. Qualcomm claims Snapdragon Reality Elite improves GPU (up to 60%), CPU (up to 30%) and NPU (up to 160%) performance versus its prior XR platform, can run a 3-billion-parameter language model at ~45 tokens/sec, and supports 4.4K per-eye at 90 fps. START offers reference designs (audio+camera, monocular, binocular) and initial white-label partners include Inspecs and O’Neill (TitanFlex). Early devices using the platform include XREAL Project Aura and an upcoming Play for Dream device.
Apple in talks with PrismML on on‑device AI
Apple is in early talks with PrismML, a Caltech spinout backed by Khosla Ventures, after the startup publicly released compressed versions of Alibaba’s open-source Qwen model that it says shrink the model from roughly 54 GB to under 4 GB. PrismML’s technique — reducing internal values to one or three possible states — aims to let a 27-billion-parameter model run on iPhone 15 or newer devices, improving speed, energy use and memory footprint at the cost of a small drop in some performance metrics. PrismML released two compressed model variants for free, has Caltech-licensed patents, and raised a $16.25 million seed round. Analysts noted the potential impact on Siri, device battery use, and global chip demand, while cautioning that real-world testing at scale will determine whether the efficiency claims hold up.
