Why Model Choice Matters
Different tasks call for different models. You might route long-form reasoning to Kimi K3, rapid generation to a fast Gemini Flash model, and complex editorial work to Claude Opus. Cosmic's model-agnostic API means you can route each task to the best available model without changing your content infrastructure.
The content stays in Cosmic. The model is a parameter.
