IBM releases Granite Switch 4.1
IBM released Granite Switch 4.1 — to handle chat, judging and speech transcription from a single endpoint, it bundles the 8B and 30B models with a judging aLoRA, a Guardian aLoRA for safety judgments and Granite-Speech-5.0-Turbo-CTC
Why it matters
Because these are activated LoRAs, the KV cache built by the base model can be reused for the judgment that follows, and IBM said GPU memory with all three components added stays close to that of the base model alone. It gave almost no numerical comparisons, only a demonstration in which a customized 3B model judged 60 to 100 items per second
