Granite Switch 4.1 combines chat, decisions and speech in one endpoint

Key points

• Granite-Switch-4.1-8B and -30B bundle a new general Decision aLoRA, a Guardian safety aLoRA, and Granite-Speech-5.0-Turbo-CTC for transcription.
• All components fit in roughly the same GPU VRAM as the base model alone, since adapters share its KV cache.
• Adapters are Activated LoRAs, so a base model generation's KV cache can be reused for later adapter decisions.
• Users can compose their own Granite Switch models from Granite Libraries adapters; an Adapter SDK for Mellea is planned.

Why it matters for marketers: Teams running chat, moderation and transcription can consolidate onto one hosted endpoint and fewer GPUs, and can build custom adapter mixes.
