W&B Inference lets you test open-source LLMs in SECONDS with zero setup, using the familiar OpenAI API format via the Weave SDK. In this walkthrough, we demo how users can seamlessly test popular models like GPT-4.1-mini, LLaMA 3.1.8B, and DeepSeek—all hosted on CoreWeave. See how LLM calls are visualized, debugged, and compared within Weave's Traces page and Playground. Learn how to switch models with just a dropdown, run side-by-side evaluations, and analyze accuracy, latency, and cost. With built-in scoring, datasets, and real-time streaming outputs, W&B Inference simplifies open-source LLM experimentation for developers, researchers, and teams. If you're looking to scale LLM testing without infrastructure headaches, this is your new secret weapon. #shorts #short
