Granite Switch 4.1.1: update models like you update software

What the article says
On 29 October 2026, IBM Granite published Granite Switch 4.1.1 on Hugging Face, a patch update to the Granite Switch family, whose 4.1 release dated from 15 October 2026. This modular architecture lets users configure a language model with specialized adapters, all reachable from a single endpoint.
Two components change: the speech recognition model granite-speech-5.0-470m-turboctc, multilingual across 10 languages with native punctuation and capitalization, and the Decision adapter in granitelib-core, which scores better on the Jev Decision Index test set. The release stays fully backward compatible with 4.1: no migration is needed and the base model is unchanged. IBM also announces tutorials and an Adapter SDK meant to let third-party developers build their own adapters, with details promised soon.
