Chatter is for developers, engineers and QA teams building applications with large language models (LLMs). It helps teams refine prompts and check how model outputs behave against repeatable test cases before using them in an application. Create prompt-based chains from calls to different model families and models, adjust model parameters, and use variables in prompts and between steps. Run test cases across models to compare responses and evaluate changes. Shared collaboration features let engineers work on chains while QA teammates define test cases, bringing prompt iteration and testing into one workspace.
