Prismag – Per-block model routing for the terminal and any IDE

Prismag is a devtool that enables per-block model routing, allowing users to assign different AI models to specific code blocks or sections directly from the terminal or any IDE. It is designed for developers who want fine-grained control over AI-assisted coding, such as using a cheaper model for boilerplate and a more powerful one for complex logic. This is interesting because it optimizes cost and performance without requiring manual context switching or external wrappers.
