HQQ - Half-Quadratic Quantization
Fast, calibration-free weight quantization supporting 8/4/3/2/1-bit precision with multiple optimized backends.
When to use HQQ
Use HQQ when:
- Quantizing models without calibration data (no dataset needed)
- Need fast quantization (minutes vs hours for GPTQ/AWQ)
- Deploying with vLLM or HuggingFace Transformers
- Fine-tuning quantized models with LoRA/PEFT
- Experimenting with extreme quantization (2-bit, 1-bit)
Key advantages:
- No calibration: Quantize any model instantly without sample data
- Multiple backends: PyTorch, ATEN, TorchAO, Marlin, BitBlas for optimized inference
- Flexible precision: 8/4/3/2/1-bit with configurable group sizes
- Framework integration: Native HuggingFace and vLLM support
- PEFT compatible: Fine-tune quantized models with LoRA

Facebook's library for efficient similarity search and clustering of dense vectors. Supports billions of vectors, GPU acceleration, and various index types (Flat, IVF, HNSW). Use for fast k-NN search, large-scale vector retrieval, or when you need pure similarity search without metadata. Best for high-performance applications.
265tensorrt-llm
Optimizes LLM inference with NVIDIA TensorRT for maximum throughput and lowest latency. Use for production deployment on NVIDIA GPUs (A100/H100), when you need 10-100x faster inference than PyTorch, or for serving models with quantization (FP8/INT4), in-flight batching, and multi-GPU scaling.
263serving-llms-vllm
Serves LLMs with high throughput using vLLM's PagedAttention and continuous batching. Use when deploying production LLM APIs, optimizing inference latency/throughput, or serving models with limited GPU memory. Supports OpenAI-compatible endpoints, quantization (GPTQ/AWQ/FP8), and tensor parallelism.
