# Granite Switch 4.1: Chat, Decisions, and Speech from One Endpoint

## Retrieval answer

**Thesis:** A composed model endpoint can expose several task modes without requiring a separate serving surface for each one.

**Thesis:** A composed model endpoint can expose several task modes without requiring a separate serving surface for each one. IBM’s Granite Switch 4.1 announcement makes that proposition concrete by combining chat, decision adapters, and speech recognition in configured models.

**Observed facts:** The announced Granite-Switch-4.1-8B and 30B configurations include a general-purpose Decision adapter, a specialized Guardian adapter, and Granite-Speech-5.0-Turbo-CTC. IBM says the composed system uses approximately the same GPU VRAM as the base model alone, and that adapter-based decisions can reuse the base model’s KV cache. The company’s Speech-to-Decisions demo transcribes audio, generates summaries, screens for harmful content, and checks user-defined flags.

**Mechanism:** Adapters provide task-specific behavior around a shared base model; IBM says KV cache reuse and a co-located speech encoder support serving multiple task modes through one endpoint. **Why now:** The release arrives as teams are assembling workflows that cross modalities and task boundaries, making endpoint count, GPU memory, and handoffs operational design choices rather than model-card details.

**Implication:** Teams can evaluate whether a single configured endpoint reduces orchestration and deployment overhead for speech-to-decision workflows. **Evidence boundary:** The source is IBM’s announcement; its comparisons, speed claims, and memory claims are vendor-reported, not independently validated here. **Watch condition:** Look for independent measurements of latency, memory use, and task quality across the combined workflow. This record starts a distinct analytical branch because no prior New Runtime record for this release was supplied.
