GPT-5.4 API Pricing & Features Guide (2026)

OpenAI recently released GPT-5.4, their most capable model yet for professional work. This guide covers everything developers need to know about pricing, features, and how to integrate it into your applications.## GPT-5.4 Pricing OverviewGPT-5.4 is priced at the premium tier, reflecting its enhanced capabilities. Here is the complete pricing structure:Model| Input (per 1M tokens)| Cached Input| Output (per 1M tokens) ---|---|---|--- GPT-5.4| $2.50| $0.25| $15.00 GPT-5.4 mini| $0.25| $0.025| $2.00 **Important:** Data residency and Regional Processing endpoints are charged an additional 10% for all GPT-5.4 models. Prompts exceeding 272K input tokens are priced at 2x the standard input rate.## Features### Native Computer UseGPT-5.4 introduces native computer use capabilities, allowing the model to interact with computers, browsers, and software interfaces directly. This is a significant upgrade for automation and agentic workflows.### Excel and Sheets IntegrationThe model now includes native plugins for Excel and Google Sheets, enabling automatic spreadsheet manipulation, formula generation, and data analysis directly through the API.### Thinking ModelsGPT-5.4 Pro includes enhanced reasoning capabilities with configurable thinking effort (none, low, medium, high, xhigh) for complex multi-step problem solving.### 1M Token Context WindowThe full GPT-5.4 model supports up to 1 million tokens in context, making it ideal for analyzing large documents, codebases, or conversation histories.## Cost Optimization Strategies* **Use Batch API:** Save 50% on both input and output tokens by running asynchronous tasks over 24 hours * **Enable Caching:** Repeated prompts can use cached input at 90% discount * **Consider GPT-5.4 mini:** For well-defined tasks, the mini version offers 10x savings * **Stay Under 272K tokens:** Avoid the 2x multiplier for prompts over this threshold## How GPT-5.4 Compares to GPT-5.2While GPT-5.4 is priced higher per token than GPT-5.2, its improved token efficiency means you often need fewer tokens to achieve the same results. The enhanced reasoning and native tool use can significantly reduce the number of API calls needed for complex tasks.## Wrapping upGPT-5.4 represents a significant advancement in AI capabilities, particularly for professional and enterprise use cases. While the pricing is premium, the enhanced reasoning, native computer use, and spreadsheet integrations can reduce overall development costs for complex workflows.
