# IBM Granite says Switch 4.1.1 updates adapters without changing the base model

[Canonical reading](https://escapemeridian.com/readings/ibm-granite-says-switch-4-1-1-updates-adapters-without-changing-fe13440c)

The IBM Granite authors describe Granite Switch 4.1.1 as a patch release that adds updated speech-to-text and Decision adapters while leaving the base model untouched. They say it is fully backwards compatible with version 4.1 and requires no migration.

The updated Granite Speech ASR model transcribes speech across 10 languages, with punctuation and capitalization. The Decision adapter in granitelib-core showed improved overall performance on the Jev Decision Index test set; the article gives no scores or details about how that test relates to use in practice.

The authors say that, apart from training the new ASR model and Decision adapter, nothing was recomputed. Their broader argument is that teams can update specialized adapters independently, rather than recomputing the base model for each update. They are working on tutorials and an Adapter SDK for developers and third-party providers to build and ship adapters, but those offerings are not described as available in this article.

An open question is whether the reported test-set improvement translates into better performance in real deployments.

The article reports improved overall performance on the Jev Decision Index test set but gives no scores or test details, so the scale and real-world relevance of the improvement are unclear. The article says tutorials and an Adapter SDK are in development; it does not establish their availability or demonstrate outcomes from third-party adapters.

### Version 1 — 2026-11-05T12:01:35.223Z

The IBM Granite authors describe Granite Switch 4.1.1 as a patch release that adds updated speech-to-text and Decision adapters while leaving the base model untouched. They say it is fully backwards compatible with version 4.1 and requires no migration.

The updated Granite Speech ASR model transcribes speech across 10 languages, with punctuation and capitalization. The Decision adapter in granitelib-core showed improved overall performance on the Jev Decision Index test set; the article gives no scores or details about how that test relates to use in practice.

The authors say that, apart from training the new ASR model and Decision adapter, nothing was recomputed. Their broader argument is that teams can update specialized adapters independently, rather than recomputing the base model for each update. They are working on tutorials and an Adapter SDK for developers and third-party providers to build and ship adapters, but those offerings are not described as available in this article.

An open question is whether the reported test-set improvement translates into better performance in real deployments.

### uncertain — 2026-11-05T12:01:35.223Z — anthropic/claude-opus-5.5

Publication: 71ce8761-2e3f-45e5-8288-fb9668abe35b

attribution — pass: The reading attributes the release and its claims to the IBM Granite authors (Kate Soule, Luis A Lastras, Subhajit Chaudhury and Abraham Daniels) in an IBM Granite post on the Hugging Face blog. The claims are kept as the authors' assertions rather than presented as established fact.

> Granite Switch 4.1.1 is a patch release.

summary — uncertain: The summary says the release 'adds updated speech-to-text and Decision adapters', but the source calls the speech component an 'ASR model' and only the Decision component an adapter. Smallest repair: say 'an updated Granite Speech ASR model and an updated Decision adapter'. Central terms also go unexplained for a general reader: adapter, base model, patch release, ASR and granitelib-core. Saying in plain words that an adapter is a smaller add-on module that gives the shared model new skills would make the main argument readable on its own.

> Apart from training the new ASR model and Decision adapter, nothing was recomputed: the base model is untouched.

date — pass: evidence.originalPublished is 2026-10-29. This matches the article's stated publication date of October 29, 2026, and the feed entry. The reading's mention of an earlier 4.1 release does not conflict with this date.

> Published
October 29, 2026

support — pass: All five claims are exact source statements. The limitations correctly note that the post gives no scores or test details and that the Adapter SDK is not yet available. The question about real-world performance follows from the missing test details and does not imply an unsupported benefit.

> We're working on tutorials and an Adapter SDK so developers and third-party providers can build their own adapters

media — pass: The selected media is the verified direct link to the original Hugging Face article, which is the most relevant way to reach the source.
