Frequently Asked Questions

Is GPT-5.4 Image 2 cheaper than GPT-5.4 Nano?

At standard usage (1,000 input tokens, 500 output tokens, 100,000 requests/month), GPT-5.4 Nano costs $82.50/month versus $1,550.00/month for GPT-5.4 Image 2 — a 95% saving. Your actual savings will vary based on your token profile; output-heavy workloads amplify differences in output pricing.

Which model has a larger context window, GPT-5.4 Image 2 or GPT-5.4 Nano?

GPT-5.4 Image 2 has a larger context window at 1,050,000 tokens, compared to 400,000 tokens for GPT-5.4 Nano. A larger context window is important for processing long documents, multi-turn conversations, or large codebases without truncation.

Do GPT-5.4 Image 2 and GPT-5.4 Nano support the Batch API?

Neither GPT-5.4 Image 2 nor GPT-5.4 Nano currently supports a batch API with discounted pricing. For batch-eligible alternatives, consider models from OpenAI, Anthropic, or Google that include batch API support.

Which model offers better prompt caching?

Neither GPT-5.4 Image 2 nor GPT-5.4 Nano currently supports prompt caching. For prompt-caching capable alternatives, consider Claude models from Anthropic or GPT-4o from OpenAI.

What are the best use cases for GPT-5.4 Image 2 vs GPT-5.4 Nano?

GPT-5.4 Image 2 is best suited for Content & copywriting, while GPT-5.4 Nano is optimized for General chatbot. Choose based on which use case matches your primary workload — and validate with the cost calculator above to confirm the total monthly spend fits your budget.

What is the cost per request for GPT-5.4 Image 2 vs GPT-5.4 Nano?

At 1,000 input tokens and 500 output tokens per request — a typical conversational workload — GPT-5.4 Image 2 costs $0.015500 per request and GPT-5.4 Nano costs $0.000825 per request. At 100,000 requests/month, that translates to $1,550.00 and $82.50 respectively. Use the interactive calculator to adjust these parameters for your actual workload.

GPT-5.4 Image 2 vs GPT-5.4 Nano: Summary

When comparing GPT-5.4 Image 2 and GPT-5.4 Nano for API cost, the right choice depends on your workload's token profile, required features, and tolerance for latency. GPT-5.4 Nano offers lower total cost at standard usage volumes (1,000 input + 500 output tokens per request at 100,000 requests/month) at $82.50/month, compared to $1,550.00/month for GPT-5.4 Image 2.

Both models are priced in USD per million tokens, the standard unit across all major AI API providers. GPT-5.4 Image 2 charges $8.00/M for input tokens and $15.00/M for output tokens. GPT-5.4 Nano charges $0.20/M input and $1.25/M output. If your workload is output-heavy (more tokens generated than consumed as input), the model with the lower output price compounds cost savings significantly at scale.

Context window capacity differs between the two: GPT-5.4 Image 2 supports up to 1,050,000 tokens in a single request, versus 400,000 tokens for GPT-5.4 Nano. A larger context window is essential for document summarization, large codebase analysis, and multi-document retrieval-augmented generation (RAG) applications.

Use the interactive calculator at the top of this page to enter your actual token usage and monthly request volume for a precise cost comparison tailored to your workload. Adjust for batch API discounts and prompt caching to find the most cost-effective option for your specific deployment.
