Eliminate LLM Cold starts: Load models up to 6x Faster with Azure Blob Storage and Run:AI Model Streamer
Stop paying for idle GPUs while model weights copy to disk. Stream them straight into GPU memory instead with Run:AI Streamer from Azure Blob Storage. The Problem: Every Cold Start Costs You More Than Money GPU compute is among the most expensive cloud infrastructure, and every second a GPU is allocated but unavailable for serving is real money lost. The cost also goes beyond your Azure bill: slow cold starts can delay responses, stress SLAs, and degrade user experience during traffic spikes, when users need capacity most. In many conventional inference deployments, a cold start triggered by auto-scalin...

For example, imagine a customer support app where users can say "give me a markdown report on the last three months of stock transactions and the value of my portfolio." Then an agent does the work. First, you need to design for security so the agent doesn't commingle data from separate cus...
