Which should you choose?

Editorial

Choose Command A if…

  • your prompts are long: it takes 256,000 tokens against 128,000

Choose GPT-4o if…

  • work can wait: it lists a batch tier and the other does not

Each reason is a fact from the tables above. Picking between them is our judgement, and we do not benchmark quality: price and context are what we can measure, so test both on your own prompts before you commit.
