Frequently Asked Questions

What is the official token pricing for GPT-4o?

GPT-4o standard pricing is $2.50 per 1 million input tokens and $10.00 per 1 million output tokens. Prompt cache reads are billed at $1.250 per 1M tokens (50% discount).

How much does GPT-4o cost per 1,000 requests?

For a typical enterprise workload (3,000 prompt tokens, 500 output tokens, 2 turns with 50% prompt cache hit), GPT-4o costs approximately $24.438 per 1,000 requests.

Does GPT-4o have a context-window cliff surcharge?

No. GPT-4o features flat, predictable unit economics up to its maximum context window of 128,000 tokens without tiered rate spikes.

What is the best budget alternative model for GPT-4o?

For high-volume non-reasoning tasks or classification, the recommended budget routing alternative is gpt-4o-mini. Routing 70% of simpler intents to this tier typically reduces monthly invoices by over 50%.
