Cost Analysis for Classification and Embedding at 1 Billion Requests
Key point
It presents a methodology for optimizing hardware-specific costs and latency for large-scale classification and embedding workloads.
Details
This addresses a cost-analysis methodology aimed at solving the massive cloud costs that arise when operating bulk embedding pipelines for large-scale document classification or RAG.
To optimize cost and latency when handling inference requests at a scale of 1 billion (1B) or more, it analyzes four key factors: hardware, deployment tools, inference servers, and load testing.
Based on an NVIDIA L4 GPU, the estimated cost to process 1 billion inputs is as follows:
- Classification (DistilBERT): approximately $253.82
- Embedding (ModernBERT): approximately $409.44
- Vision embedding (ColQwen2): approximately $44,496.51
For efficient serving, it recommends using Infinity and TEI (Text Embeddings Inference), with Infinity in particular having strengths in multimodal embedding support and compatibility with a variety of hardware.
