Paper AbstractExpand

Language model systems built around proprietary APIs often operate on a token-based cost model. This becomes prohibitively expensive in the context of large databases, where LM-enhanced relational operators can incur costs exceeding $10,000 for a single set of experiments, hindering thorough research and practical deployment. In this paper, we demonstrate that quantized, open-weight models running locally on just 16GB of VRAM can match or exceed the accuracy of closed-source counterparts at lower latency and a fraction of the price, challenging the prevailing assumption that closed-source LM APIs are necessary for effective LM-database integration. We present and analyze the key system optimizations required to efficiently deploy these open-weight models within an LM-DB system. By integrating these local models into the BlendSQL v0.1.0 framework, we demonstrate a 390x reduction in overall costs and 3.8x reduction in latency compared to a proprietary LM API.

Large Databases Need Small, Open-Weight Language Models

This paper addresses the high financial and operational barriers associated with using proprietary language model APIs for large-scale database tasks. When language models are used to enhance relational database operators, the token-based costs of closed-source systems can exceed $10,000 for a single research experiment. The authors propose a shift toward using quantized, open-weight models that run locally, demonstrating that these smaller models can achieve equal or better performance than proprietary alternatives while significantly reducing costs and latency.

The Problem with Proprietary APIs

Current language model systems often rely on proprietary APIs that charge based on the number of tokens processed. In the context of large databases, where complex queries require extensive interaction with language models, these costs become prohibitively expensive. This pricing model acts as a major bottleneck, preventing researchers and developers from performing thorough experiments or deploying language model-enhanced database systems in practical, real-world environments.

Local Optimization and Deployment

The authors demonstrate that it is not necessary to rely on expensive, closed-source models to achieve effective language model-database integration. By using quantized, open-weight models that require only 16GB of VRAM, the researchers were able to run these systems locally. The paper outlines the specific system optimizations required to integrate these local models into the BlendSQL v0.1.0 framework, proving that local deployment is a viable and efficient alternative to cloud-based APIs.

Significant Gains in Efficiency

By replacing proprietary APIs with local, open-weight models, the researchers achieved substantial performance improvements. When integrated into the BlendSQL v0.1.0 framework, the local model approach resulted in a 390x reduction in overall costs and a 3.8x reduction in latency. These results challenge the prevailing industry assumption that proprietary APIs are a requirement for high-performance language model-database integration, suggesting that smaller, locally hosted models are a more sustainable path forward for data-intensive applications.
