Which Should You Pick?

Pick IBM Granite 4.0 if...

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.

Pick Hermes Agent if...

  • Higher output quality (9 vs 8)

Power users and technical teams who will actually use an agent daily, give it real work, and benefit from a learning loop. Teams running it on a real server with Docker or Modal sandboxing get the most out of it. Also the right pick if you care about model sovereignty -- it runs on anything.
