GPT-5.4 Mini, 플래그십 모델에 준하는 성능을 훨씬 저렴한 비용으로 달성 — 전체 비교 분석
Why it matters
OpenAI released GPT-5.4 Mini and Nano, budget models designed to serve as sub-agents in multi-agent architectures, competing with Anthropic's Claude Haiku 4.5. Mini nearly matches flagship performance at significantly lower cost, with Nano being the cheapest option at $0.20/$1.25 per million tokens. Key differentiators include pricing tiers, context window sizes (400K for Mini/Nano vs 200K for Haiku), and ecosystem fit for orchestrator-delegated workflows.
