Executes large language models locally across CPU, GPU, and NPU hardware through a layered architecture that abstracts hardware differences via a plugin system. The Go SDK provides type-safe interfaces (Create/Destroy lifecycle) that route inference requests through CGo bindings to C/C++ hardware plugins, enabling day-0 support for models like GPT-OSS, Granite-4, Qwen-3, and Llama-3 without cloud dependencies. Model formats (GGUF, MLX, NEXA) are handled by format-specific plugins that optimize for target hardware capabilities.
Unique: Plugin-based hardware abstraction layer (Layer 5) decouples model inference from hardware implementation, enabling day-0 support for new models and NPU architectures without SDK recompilation. CGo bridge (Layer 4) provides zero-copy memory management across language boundaries, critical for mobile/IoT where memory is constrained.
vs alternatives: Supports NPU inference natively (Qualcomm, AMD, Intel) unlike Ollama or LM Studio which focus on GPU/CPU, and provides mobile SDKs (Android/iOS) that competitors lack, making it the only true cross-device inference framework.
Processes images and text together through VLM models (Qwen-3-VL, etc.) using a unified Go SDK interface that handles image encoding, tokenization, and vision-specific hardware optimizations. The VLM plugin system manages image preprocessing (resizing, normalization) and routes vision tokens through specialized hardware paths (GPU tensor cores for image encoding, NPU for attention). Supports batch image processing and maintains image context across multi-turn conversations.
Unique: VLM plugin architecture (runner/nexa-sdk/vlm.go) separates image encoding from text generation, allowing hardware-specific optimization of vision towers (GPU tensor cores for image embeddings) while text generation runs on NPU, maximizing throughput on heterogeneous hardware.
