GPT-5.4
Excellent general-purpose reasoning and broad world knowledge, with strong performance on coding, math, and multi-modal (image + file) inputs.
Output tokens are priced well above input tokens, so verbose responses dominate cost — tight max-token limits and prompt caching matter.
GPT-5.4 Mini
Good default for everyday chat, summarization, and lightweight agent steps where GPT-5.4-level reasoning isn't required.
Quality gap widens on long, multi-hop reasoning tasks — needs careful prompt design to avoid silent failures on edge cases.
