Frequently asked questions
Is Granite 4.0 Micro as good as GPT-4o-mini?
Granite 4.0 Micro is open-weight and competitive on many tasks, but GPT-4o-mini may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Can I run Granite 4.0 Micro locally?
Yes. Granite 4.0 Micro has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. GPT-4o-mini is API-only and cannot be self-hosted.
How much cheaper is Granite 4.0 Micro?
Granite 4.0 Micro costs $0.11/M output vs $0.6/M for GPT-4o-mini — roughly 5x cheaper via API, and free if you self-host.
Granite 4.0 Micro vs GPT-4o-mini — which should I pick in 2026?
Choose Granite 4.0 Micro if you want to self-host, keep your data private and skip per-token fees — it's open-weight and runs on your own hardware. Choose GPT-4o-mini if you want frontier capability through a managed API with zero infrastructure to run.
