GLM 5.3 Hosted by Mistral

Mistral made GLM 5.3, hosted on Mistral, the default model in its Vibe Code product and web app as of September 21, 2026, according to a post from the @mistralvibe account. The hosted GLM 5.3 configuration includes a 1M context window and what Mistral described as generous limits. The post drew 46.6K views, with one reply from @UrbiGT criticizing the move as a sign Mistral can no longer produce competitive models of its own.
