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.

It is served anonymously under OpenRouter's stealth namespace: the lab behind it has not been disclosed, and it will move to its own namespace when it is.

Facts and pricing

Provider: Stealth
Context window: 1.0M tokens
Input price: 0 credits / 1M tokens ($0 raw)
Output price: 0 credits / 1M tokens ($0 raw)
Vision (image input): Yes

Extended reasoning: No

Credits are what Zeplik bills: 1 credit = $0.10, computed from the raw provider rate with a 1.20x margin. Raw prices shown per 1M tokens.

What Crouton Alpha is best for

Balanced everyday work: writing, questions, brainstorming and summarization
Very long documents and codebases: a 1.0M-token window fits entire books or repositories in one conversation
Working with images: screenshots, charts, photos and scanned documents alongside text
Tool use and agents: reliably calls functions, so it can search, run skills and drive workflows

Example prompts
