GPT-5.5 vs GPT-5.4 mini
How GPT-5.5 (OpenAI) and GPT-5.4 mini (OpenAI) compare on price, context window and best-fit use case.
In short: GPT-5.5 is best for Highest-stakes reasoning, complex agents, and frontier coding tasks where capability outweighs cost, while GPT-5.4 mini suits High-volume tasks like classification, extraction, and chat where cost and speed matter most. On price it's $5.00 vs $0.75 per 1M input tokens; on context, ~1.05M tokens (128K max output) vs ~400K tokens.
