Crouton Alpha

Crouton Alpha is a lightweight model built for scalable coding, agentic, and multimodal workflows. It's ideal for executing agentic sub-tasks, tool use, and document analysis in high-volume, repeated work. Developers can combine it with frontier reasoning models to execute the bounded steps that turn plans and information into action.

Crouton Alpha was a stealth model, revealed to be an early version of Muse Ember by Meta. OpenRouter routed requests to it and was not its developer, owner, or provider. Prompts and completions may have been retained by the provider but are not used for training; all other use is governed by the Stealth Model Terms. The stealth period has ended; use Muse Ember at https://openrouter.ai/meta/muse-ember.
