Which Should You Pick?

Pick IBM Granite 4.0 if...

  • Higher output quality (8 vs 7)
  • Better value for money (9.5/10)
  • More features (8.5 vs 7)

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.
