Crouton Alpha, a soggy cartoon crouton in tomato soup saying Zut alors, beside a Blocked in Europe stamp, 1M context, audio and video input, and Meta as the likely maker, though not a Muse we know.

Crouton Alpha reasons like Meta's Muse models, but it counts tokens like none of them. Our lead: a new model from Meta.

Compare it with Muse Wonder

The case file. First seen 3 Nov 2026, revealed not yet, developer unknown, likely Meta, context 1,048,576 tokens, input text, images, audio, video and files, tool calls yes, speed in our tests about 175 tok/s. 3 Nov 2026: appears free on OpenRouter and OpenCode with no developer's name, and both turn away our requests from Europe. 3 Nov 2026, our finding: of 454 models on OpenRouter, only Meta's Muse Wonder and Muse Spark 1.3 offer the same six reasoning levels. 4 Nov 2026, our finding: its token counts match no model we know, and the Muse models agree with it on 2 of 24 phrases.

So far Crouton Alpha is only a hosted preview. If it turns out to be an open model, for example a new open Muse like Muse Spark Open, we'll put GGUF files for llama.cpp here, as we did for GLM-5.3-Flash and MiniMax M3.1 Flash.
