Scores come from live data — output price (cost), context length, open vs closed weights (openness & self-hosting) and vision/tool support (multimodality). Raw task quality isn't scored here; it depends on your benchmark — see the verdict.
Granite 4.1 8B is a dense, decoder-only 8-billion-parameter language model from IBM, part of the Granite 4.1 family. It supports a 131K-token context window and is designed for enterprise tasks...
OpenAI's flagship model, GPT-4 is a large-scale multimodal language model capable of solving difficult problems with greater accuracy than previous models due to its broader general knowledge and advanced reasoning...
These variants are tracked but not compared here — one page per family keeps the comparison readable.
Granite 4.1 8B is open-weight and competitive on many tasks, but GPT-4 may still lead on the hardest reasoning and agentic work. The gap keeps narrowing — benchmark both on your actual use case before deciding.
Yes. Granite 4.1 8B has open weights, so you can self-host it on your own GPUs or run it via a low-cost API. GPT-4 is API-only and cannot be self-hosted.
Granite 4.1 8B costs $0.1/M output vs $60/M for GPT-4 — roughly 600x cheaper via API, and free if you self-host.
Choose Granite 4.1 8B 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-4 if you want frontier capability through a managed API with zero infrastructure to run.
