FAQ

Common questions about OpenAI: GPT-5.4 Mini
---

[Read the docs ](https://docs.modelslab.com)

### What is GPT-5.4 Mini and how does it differ from GPT-5.4?

GPT-5.4 Mini is OpenAI's fastest small LLM, delivering 2x faster responses than its predecessor while maintaining near-flagship performance on coding and reasoning tasks. It's optimized for high-volume workloads, agentic systems, and real-time applications where speed matters.

### What are the main use cases for OpenAI GPT-5.4 Mini?

GPT-5.4 Mini excels at coding assistance, computer use automation, tool calling, real-time image reasoning, code reviews, data extraction, and spawning multiple sub-agents. It's ideal when you need sub-second responses without sacrificing capability.

### How much does the OpenAI GPT-5.4 Mini API cost?

Pricing is $0.75 per 1M input tokens and $4.50 per 1M output tokens. Cached input tokens cost $0.075 per 1M, reducing costs for repeated context. Regional data residency endpoints incur a 10% uplift.

### What features does GPT-5.4 Mini support in the API?

GPT-5.4 Mini supports text and image inputs, tool use, function calling, web search, file search, computer use, and skills. It includes a 400k context window and up to 128k max output tokens.

### Is GPT-5.4 Mini suitable for production applications?

Yes. GPT-5.4 Mini approaches full GPT-5.4 performance on complex benchmarks like SWE-Bench Pro while delivering 2x faster inference, making it production-ready for coding, agents, and real-time workflows at scale.

### How does GPT-5.4 Mini compare to GPT-5.4 Nano?

GPT-5.4 Mini is more capable and faster, ideal for coding and complex tasks. GPT-5.4 Nano is the smallest and cheapest option, best for classification, data extraction, and lightweight tasks where performance requirements are lower.
