Teams are building AI into the places where work already happens, across documents, spreadsheets, presentations, software systems, tools, and business workflows. GPT-5.4 brings frontier reasoning, strong coding performance, computer-use capabilities, and long-context support to applications that need to operate across those environments.
GPT-5.4 helps developers build AI applications and production workflows that can interpret context, interact with tools, operate software environments, and verify outputs across multiple steps. It is well suited for professional workflows that require reliable reasoning and action across complex business systems.
Through OpenAI APIs and Amazon Bedrock, organizations can build reliable AI applications and production workflows with GPT-5.4s frontier reasoning capabilities and the AWS controls they already use.

You pay per token used, with no upfront commitment. Pricing splits into input tokens, output tokens, cached input tokens, and cache read tokens. Each token type is priced across four service levels: standard, priority, flex, and batch. Separate rates apply for long-context requests. Many dimensions carry an AWS Region prefix (for example USE1, EUC1, APS1), so your rate depends on the Region and whether you use global routing. Output tokens generally cost more than input tokens, and cached or batch usage is billed differently from standard real-time calls.
Top-of-mind questions for buyers
What counts as one billable token for input and output charges?
A token is a small chunk of text the model processes, roughly a few characters or part of a word. You are billed per token sent in your prompt (input) and per token the model generates (output). Longer prompts and longer responses raise your token count.
What is the difference between standard, priority, flex, and batch service levels?
Each level meters the same tokens but sets a different rate. Standard handles real-time calls. Priority targets faster handling. Flex suits workloads that tolerate variable timing. Batch groups requests for asynchronous processing. You choose the level per request, and the matching rate applies to those tokens.
How do cached input tokens and cache read tokens change my bill?
Cached input tokens and cache read tokens are billed at separate rates from standard input tokens. When your prompt reuses previously processed content, those tokens meter under the cache dimensions instead of full input rates. This affects repeated prompts that share common context across calls.
