Apple (AAPL) stock climbed 0.44% during Wednesday trading following reports that the iPhone maker is engaged in discussions with PrismML, an artificial intelligence startup that emerged from the California Institute of Technology. The negotiations focus on PrismML’s proprietary technology that enables a 27-billion-parameter artificial intelligence model to operate entirely on an iPhone 17 Pro device, eliminating the need for cloud-based processing. PrismML managed to compress the open-source Qwen 3.6 model from Alibaba’s portfolio, shrinking it from approximately 54 gigabytes to below 4 gigabytes, representing a compression ratio exceeding 90%. The company accomplishes this through ultra-compact 1-bit and ternary weight structures, slashing memory demands by as much as 14 times while delivering speeds up to 8 times faster than conventional architectures. PrismML’s innovation maintains full activation of all 27 billion parameters concurrently, enabling sophisticated operations including logical reasoning, autonomous agent functionality, and software development tasks. The open-source iteration of this model is scheduled for public release next Tuesday. Presently, Apple’s most sophisticated Siri capabilities depend on Google’s Gemini models executing on Nvidia silicon within Google Cloud infrastructure. Khosla Ventures led PrismML’s $16.25 million seed funding round completed in early 2024.
