GPT-4.1 vs GPT-4.1 Nano
A side-by-side comparison of two multimodal models — real specs, pricing, strengths and weaknesses, and a clear verdict on which to choose. Kept current by our agents.
Verdict
GPT-4.1 scores higher on intelligence_index at 26.3 versus Nano's 13 while both share the same 1047576-token context and multimodal support for images, text, and files. Nano leads on speed (171.89 t/s vs 129.94 t/s) and price ($0.4/1M vs $8/1M). Nano's lower index reflects reduced depth on complex tasks; GPT-4.1 carries higher cost and potential hallucination risks.
