The decision
Use-case anchors and category strengths, side by side.
Regulated-industry enterprises (healthcare, finance, government) who need Apache 2.0 open-weight models with ISO 42001 certification. Also ideal for edge deployments where Granite Nano (350M / 1.5B) is one of the few open models that runs realistically on CPU. And for any Mamba-hybrid research or low-memory production use where the 70-80% memory reduction actually changes the economics.

The two tools aren't fighting for the same person -- they're aiming at adjacent jobs that occasionally overlap.
