Cactus

Cactus is a numerical computing framework and AI inference engine optimized specifically for mobile phones, focusing on energy-efficient performance on a wide range of devices. It enables running custom machine learning models and scientific computations efficiently on ARM CPUs, supporting older and newer phones without relying heavily on GPUs or specialized NPUs, which many mobile devices lack.

The app offers fast, low-power kernel implementations that reduce battery drain and device heating, making it suitable for AI applications on phones where power consumption and thermal management are critical. Cactus supports INT4 and INT8 integer precision computations for improved speed and energy efficiency. Its design emphasizes compatibility with diverse phone hardware, including ARM CPUs and plans for support of NPUs, DSPs, and ISPs, enhancing AI inference by leveraging available hardware accelerators without compromising battery life.

Developed primarily in C++, with supplementary Python and shell components, Cactus aims to provide scalable numerical computation and AI inference capabilities adaptable for mobile environments. This allows developers to implement and deploy efficient AI models on consumer smartphones seamlessly, emphasizing performance and resource optimization.

Key capabilities include:

• Energy-efficient AI inference optimized for ARM-based phone CPUs
• Support for custom numerical computing models similar to frameworks like JAX
• Compatibility with a broad spectrum of mobile devices, including those without neural processing units
• Integer precision optimization (INT4, INT8) for balancing speed and power consumption
• Reduced GPU dependence to minimize battery drain and device heating

Cactus is suitable for developers looking to integrate AI inference on mobile devices with constrained power and thermal budgets, offering an alternative to GPU and NPU-centric frameworks by prioritizing CPU-based performance and efficiency.
