GPT-4.1 Mini or GPT-5.4 Nano: which to pick

Only GPT-5.4 Nano has a coding score, 44.8 on the Vibe Coding Index; GPT-4.1 Mini has none, so the two cannot be ranked on coding.

Pick GPT-4.1 Mini for a larger context window (1.05M against 400K tokens) and work measured by Kagi LLM Benchmark or MMLU Pro, where it leads.

Which one for your work

Each card is decided by one number both models carry. Where only one has it, the card says so and makes no call.
