IBM releases Granite Switch 4.1 models
What happened
On 16 October 2026, IBM released Granite Switch 4.1 on Hugging Face, comprising the Granite-Switch-4.1-8B and -30B versions. The model combines a general-purpose decision aLoRA, a safety decision Guardian aLoRA and the ASR model Granite-Speech-5.0-Turbo-CTC into a single model, and is said to support conversation, decision-making and speech from one endpoint while using roughly the same VRAM as running the base model alone. Granite-Speech-5.0-Turbo-CTC is reported to be the fastest ASR model on the OpenASR leaderboard. So far this is the only report on the matter, with no follow-up updates or contradictions from other reports.

Introduced last spring, the Granite Switch project enables a modular approach to model development. Now Granite Switch 4.1 models, armed with a Decision adapter and the fastest ASR model on the OpenASR leaderboard, can move efficiently between natural-language responses, general and specialized decisions, and speech-to-text tasks—all from one hosted endpoint.
