Which should you pick?

On a typical workload, MiniMax M2.5 costs $135/mo against GPT-5.4 nano's $185/mo — roughly 1.4× cheaper. But the ranking depends on your output-to-input ratio: output is the pricier direction for both, so an output-heavy job (code generation, long answers) widens the gap while an input-heavy one (summarization, retrieval) narrows it. If you need to fit more in a single prompt, GPT-5.4 nano has the larger 400K-token window (~600 pages). Only GPT-5.4 nano accepts image input — decisive if your prompts include images.

These are list and routed market prices, not measured outcomes. Two models at the same rate can still cost different amounts to finish the same task, because verbose or reasoning-heavy models emit more tokens. That gap is exactly what measured cost-per-task captures.

Frequently asked questions

Is GPT-5.4 nano or MiniMax M2.5 cheaper?

For a typical workload (1,500 input + 500 output tokens × 200,000 requests/month), MiniMax M2.5 costs $135/mo versus $185/mo for GPT-5.4 nano — about 1.4× less. Because output is priced higher than input, the winner can flip if your workload writes much more or less than this; check your own numbers in the calculator.

What's the main difference between GPT-5.4 nano and MiniMax M2.5?

On price, GPT-5.4 nano is $0.20/$1.25 per 1M (in/out) and MiniMax M2.5 is $0.15/$0.90. GPT-5.4 nano has the larger context window at 400K tokens. GPT-5.4 nano also accepts image input, while MiniMax M2.5 is text-only.
