Unique: OPT's small size (125M) makes quantization less critical than for larger models, but the permissive license enables unrestricted quantization and redistribution, unlike proprietary models; community has published multiple quantized variants (GGML, GPTQ)

vs others: Easier to quantize than larger models due to smaller size, but quantized quality still lower than larger quantized models (LLaMA-7B INT4); better for extreme edge constraints than quality-critical edge applications
