Frequently asked questions
How much does GPT-5.4 cost?
GPT-5.4 costs $2.50 per 1M input tokens and $15.00 per 1M output tokens, sourced from openai. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.
What is the context window of GPT-5.4?
GPT-5.4 has a context window of 1.05M tokens, with a max output of 128K tokens per reply. This is the total combined size of prompt + completion.
Does GPT-5.4 support tool calling?
Yes. GPT-5.4 supports tool calling (function calling). This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Does GPT-5.4 support structured output / JSON mode?
Yes. GPT-5.4 supports structured output / JSON-schema-constrained decoding. This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Can GPT-5.4 accept image input?
Yes. GPT-5.4 accepts both text and image input. Vision pricing per image is usually billed on top of the regular token rate — check OpenAI's docs for the exact rule.
Is GPT-5.4 open-weight?
No. GPT-5.4 is a proprietary model — only OpenAI (and any approved hosting partners) can serve it. The pricing above reflects the cheapest API access.
What are the best alternatives to GPT-5.4?
If GPT-5.4 doesn't fit, consider GPT OSS 120B, GPT OSS 20B, GPT-5.2. Each one targets the same use case — see the Related links below for direct head-to-head pages.
Where does this data come from?
All numbers come from the public models.dev API and are normalised into a single canonical model record. We re-pull daily and write any changes (price, context, capability) to the /changelog page.
