Batch Inference With Dynamic Batching And Variable Sequence Lengths

C/C++ LLM inference — GGUF quantization, GPU offloading, foundation for local AI tools.

Unique: Implements padding-free batching with variable sequence lengths using custom kernels, avoiding wasted computation on padding tokens — most inference engines use padded batching which wastes 20-40% compute on variable-length inputs

Optimized quantized LLM inference for consumer GPUs — EXL2/GPTQ, flash attention, memory-efficient.
