How GPT-OSS 120B and GPT Image 1 differ
What the numbers mean in practice when choosing between GPT-OSS 120B and GPT Image 1.
-
GPT-OSS 120B is an open-weight model with no per-token licensing fees, while GPT Image 1 charges $5 per million input tokens.
-
These are different kinds of model: GPT-OSS 120B is a text model while GPT Image 1 is an image model, so they often complement each other in a workflow rather than compete.
Strengths side by side
Where each model shines, according to benchmarks and provider positioning.
GPT-OSS 120B
