How GPT-5.4 compares
The nearest models people weigh against it, and what actually separates them.
vs GPT-6 Astra — Against GPT-6 Astra (OpenAI), GPT-5.4 runs about 71% cheaper per token, gives up 3.9x on context and answers faster. Take GPT-5.4 unless you specifically need what GPT-6 Astra does better.
vs GPT-5.5 — Against GPT-5.5 (OpenAI), GPT-5.4 runs about 50% cheaper per token and gives up 3.7x on context. Take GPT-5.4 unless you specifically need what GPT-5.5 does better.
vs GPT-5.6 Terra — Against GPT-5.6 Terra (OpenAI), GPT-5.4 costs about 20% more per token and gives up 3.9x on context. GPT-5.6 Terra is the one to check first if the price difference matters more than the ceiling.

Launched at $2.50/$15, cut to $2/$12 on July 30, 2026. Long-context above 272K: $4/$18. Part of the government-reviewed GPT-5.6 family, fully public July 9, 2026.
GPT-5.4 costs $2.5 per million input tokens and $15 per million output tokens on the API, with cached input at $0.25 per million. A month of 10M input and 2M output tokens runs about $55.00 at list price, before any batch or caching discounts.
What is the context window of GPT-5.4?
GPT-5.4 has a 1.1M tokens context window, with up to 128k tokens of output per response. That is the total of prompt plus response the model can hold in one request.
What is the knowledge cutoff of GPT-5.4?
GPT-5.4's training data runs through August 31, 2025, and the model was released on March 5, 2026. For anything after that date it needs web search or documents in the prompt.
What is GPT-5.4 best for?
GPT-5.4 is best for agentic workflows, desktop automation, and complex multi-step reasoning. It is a strong fit when that workflow matters more than the tradeoffs around premium pricing and balanced speed.
When should I avoid GPT-5.4?
You need the highest current coding benchmark scores — Claude Opus 4.7 and GPT-5.5 are newer premium picks.
What is a cheaper alternative to GPT-5.4?
GPT-5.6 Terra (OpenAI) at $2.00/1M/1M input against GPT-5.4's $2.50/1M/1M — roughly 20% less per token all in. Best OpenAI value — near-flagship capability at 60% off. Compare it first if GPT-5.4's pricing is the thing stopping you.
What is a faster alternative to GPT-5.4?
GPT-6 Astra — deliberate against GPT-5.4's balanced, with 1.1M tokens of context. Worth the swap when response time is what your users notice rather than the last few points of reasoning depth.
