Choose Granite 4.2 30B when
On-prem enterprise agents, air-gapped tool-calling assistants, and switchable reasoning for support or coding.
Choose Muse Glimmer 30B when
Local coding and research agents that must read screenshots, charts, or documents as images.
Short verdict
Granite is the IBM text reasoning 30B. Muse is the Meta multimodal local 30B.
Key differences
Granite 4.2 30B is text-only with 128K native and 512K extension, plus a thinking switch. Muse Glimmer 30B adds a perception encoder, image input, and four reasoning efforts at 131K+ context.
Best for
Pick Granite for regulated on-prem text agents. Pick Muse when the agent must see the screen or a document image.
Reasoning fit
Match thinking-off Granite against Muse low effort if you care about latency, not only peak scores.
Coding workflow fit
Include image-bearing tickets only on Muse. Text diffs can go either way.
Multimodal fit
No image path on Granite. No audio path on Muse.
Enterprise fit
IBM docs and family sizes vs Meta Hugging Face distribution. Procurement is not the same as a license string.
Who should not choose this?
- Do not choose Granite 4.2 30B for screenshot agents.
- Do not choose Muse as a substitute for Granite Speech ASR.
- Do not treat this as a three-way with Qwen3.8-27B.
Cost considerations
GPU memory at 30B dense plus context. 512K Granite and long Muse contexts are not free.
Limitations
September 2026 catalog verification.
Final recommendation
Default Granite when vision is unused and IBM's on-prem story matters. Default Muse when local agents must read images.
