This estimate uses normalized public API pricing per 1M tokens. It is a planning aid, not a billing quote. Verify provider pricing, limits, and terms before production use.
Quick Decision
GPT-5.4 has the lower input price, GPT-5.4 has the lower output price, and Tie offers the larger context window.
For a 1M input token plus 500K output token workload, the estimated API cost is $20 for OpenAI GPT Latest and $10 for GPT-5.4.
Choose OpenAI GPT Latest when its provider, model quality, latency, or availability is more important than the numeric price/context winner.
Choose GPT-5.4 when you care most about lower input-token price, and lower output-token price.

Use-Case Decision Matrix
| Use case | Better pick | Why |
|---|---|---|
| Budget-constrained production | GPT-5.4 | On the standard 1M input plus 500K output workload, GPT-5.4 is estimated at $10 vs $20 for OpenAI GPT Latest, saving $10 (50% lower). |
| High-volume input processing | GPT-5.4 | Lower prompt-token price matters most when prompts or retrieved passages dominate the bill. |
| Long responses and chatbots | GPT-5.4 | Lower output-token price matters most when assistants generate many completion tokens. |
| RAG or long-document work | Tie | A larger context window leaves more room for retrieved passages and source files. |
