M1 by Montage is an API built for developers who embed AI agents in products and are tired of watching inference costs balloon every time the agent has to paint a screen. Instead of asking the model to generate HTML or React on the fly, you emit a small intent schema from your agent; Montage compiles it into polished, interactive UI components on its servers and hosts them as live web views with persistent state. The result: rendering is 10x faster, token usage drops 50–100x, output is consistent across model versions and frameworks, and the components automatically match your brand styles. One M1 API call replaces an entire back-and-forth of UI generation prompts. Works with any LLM and any frontend stack.
