Migrate From OpenAI to Cerebrium: Cost-Predictable AI Inference in Two Lines of Code
2025-07-22
This guide demonstrates migrating an AI application from OpenAI's convenient APIs to Cerebrium's serverless AI infrastructure. By changing just two lines of code, you can switch from OpenAI's token-based billing to Cerebrium's time-based pricing, enabling cost predictability. The tutorial walks through building an OpenAI chatbot, configuring a Cerebrium endpoint using vLLM and the open-source Llama 3.1 model, and adding performance and cost tracking to compare both approaches. The migrated application runs on your infrastructure, offering greater flexibility, control, and data privacy.
