Overview
Fast LLM inference engine for consumer-grade hardware
Pros
- ✓ 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
Cons
- ✗ 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
Key Features
- ⚡2-4x Adaptive Sparse Speedup: Dynamically activates only necessary neural network layers during inference, achieving 2-4x faster token generation compared to standard dense computation on consumer hardware.
- 💻GPU+CPU Hybrid Execution: Intelligently distributes model computation across consumer-grade GPUs and CPUs simultaneously, maximizing throughput on heterogeneous hardware without requiring enterprise-class accelerators.
- 🔒Completely Offline Inference: Zero external API dependencies—run full LLM inference locally with guaranteed data privacy. No telemetry or cloud requirements, keeping sensitive inputs entirely on-device.
- 📦Large Model Support on Limited VRAM: Load and run multi-billion parameter models on consumer GPUs with 4-8GB VRAM through aggressive memory optimization and smart layer scheduling.
- 🎯Per-Token Latency Optimization: Focuses inference scheduling on reducing per-token generation time rather than throughput, ideal for interactive chatbots and real-time applications on constrained devices.
