Batch Inference With Dynamic Sequence Length Handling

via “batch inference with variable-length sequence padding and masking”

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

Unique: Automatically handles padding, mask generation, and unpadding for variable-length sequences in a batch, abstracting away manual sequence length management. This simplifies the API and reduces the likelihood of masking errors.

vs others: Simpler to use than manual padding and masking because the framework handles all sequence length management automatically, whereas naive approaches require the caller to manually pad sequences, generate masks, and unpad outputs.
