Hybrid AI Inference: Local LiteLLM Proxy with Remote Vast.ai GPU

The rapidly evolving landscape of AI inference is pushing organizations to seek cost-effective solutions without compromising performance or control, leading to a hybrid approach that combines local control with remote GPU resources. This approach utilizes LiteLLM, a Python SDK and proxy server that offers a unified OpenAI-compatible interface for over 100 LLM APIs, and Vast.ai, a GPU marketplace with pay-as-you-go pricing that can save users up to 80% compared to traditional cloud services. The hybrid architecture involves deploying a vLLM server with the DeepSeek-R1 model on Vast.ai, configuring LiteLLM to proxy requests locally, and testing the pipeline using OpenAI client libraries, resulting in a flexible and cost-effective inference setup. This setup allows local control over request routing, logging, and configuration, while enabling API compatibility and flexibility in experimenting with different models and providers, making it an attractive option for AI-powered applications, research, and optimization of ML pipelines.
