Choose GPT-5.4 if you want the OpenAI daily driver — strong and well-priced. Choose MiniMax M3 if you want open-weight autonomous agents that lean on tool use.
Editorially it's close: each model leads in 2 of our five dimensions. On price, GPT-5.4 runs about $6.25 per 1M tokens (blended) and is proprietary; MiniMax M3 is about $0.57 and open-weight.
The model picks the moves; the agent runs the loop, the tools, and the guardrails. Once you've chosen a model, see which agent gets the most out of it.
