Overview

Fast LLM inference engine for consumer-grade hardware

✓ Runs large language models efficiently on consumer GPUs and CPUs without cloud costs
✓ Achieves 2-4x speedup over standard inference through adaptive sparse computation
✓ Complete data privacy with offline-first architecture, zero external API calls required
✓ Optimized for resource-constrained environments, supports NVIDIA, AMD, and Intel hardware

✗ Requires manual compilation and CUDA/cuDNN setup for GPU acceleration on Linux/macOS
✗ Limited model support compared to larger frameworks; primarily optimized for specific LLM architectures

• {'icon': '💻', 'title': 'GPU+CPU Hybrid Execution', 'desc': 'Intelligently distributes model computation across consumer-grade GPUs and CPUs simultaneously, maximizing throughput on heterogeneous hardware without requiring enterprise-class accelerators.'}
• {'icon': '🔒', 'title': 'Completely Offline Inference', 'desc': 'Zero external API dependencies—run full LLM inference locally with guaranteed data privacy. No telemetry or cloud requirements, keeping sensitive inputs entirely on-device.'}
• {'icon': '📦', 'title': 'Large Model Support on Limited VRAM', 'desc': 'Load and run multi-billion parameter models on consumer GPUs with 4-8GB VRAM through aggressive memory optimization and smart layer scheduling.'}
• {'icon': '🎯', 'title': 'Per-Token Latency Optimization', 'desc': 'Focuses inference scheduling on reducing per-token generation time rather than throughput, ideal for interactive chatbots and real-time applications on constrained devices.'}
