Nexa SDK enables running frontier LLMs and multimodal models locally across PC, mobile, IoT, and wearables with automatic hardware acceleration for GPU, NPU, and CPU. It supports Qwen, Gemma, Llama, DeepSeek models with Python/C++ desktop SDKs, Android/iOS mobile SDKs, and Docker for edge deployment. Includes an OpenAI-compatible API server with chat and function calling support.

Nexa SDK abstracts the complexity of deploying AI models across heterogeneous devices by providing a unified runtime that automatically detects and routes workloads to the optimal hardware accelerator. Whether a device has an Apple Neural Engine, Snapdragon NPU, discrete GPU, or only a CPU, the NexaML runtime layer handles backend selection transparently. Developers write inference code once and deploy across PCs, smartphones, IoT devices, and wearables without platform-specific modifications.

The SDK provides day-zero compatibility with frontier open models including Qwen, Gemma, Llama, DeepSeek, and IBM Granite variants. It covers text generation, vision-language understanding, speech-to-text, text-to-speech, and image generation across all supported platforms. The OpenAI-compatible server mode enables serving local models through standard API endpoints, making it possible to use familiar chat interfaces and function-calling patterns without cloud dependencies.

Platform-specific SDKs are available for Python and C++ on desktop and server environments, native Android and iOS for mobile development, and Docker containers for Linux and IoT edge deployments. ARM SIMD kernels ensure efficient inference on resource-constrained devices, while zero-copy computation graphs minimize memory overhead. For organizations building privacy-sensitive applications in healthcare, finance, or enterprise contexts, Nexa SDK provides the infrastructure to keep all data processing on-device while maintaining the quality of modern AI capabilities.
