Inference engineering, a critical but often overlooked layer in LLM operations, significantly impacts costs by managing factors like quantization, speculative decoding, and MoE routing. Innovations such as FP8 KV cache and prompt caching are emerging to optimize token efficiency and reduce expenses. For instance, a team using Claude Sonnet 4.6 incurred approximately $4,800 in monthly costs, with the model itself accounting for $960, while the remaining $3,840 was attributed to this inference layer.
