Frequently Asked Questions about GPT-4o

Short answers grounded in the catalog fields used by this calculator. Adjust assumptions in the tool above for your real traffic mix.

How does GPT-4o performance compare to other models?

Based on our catalog benchmarks, GPT-4o is evaluated across coding, logic, math, and instruction following. Use the performance radar chart above to see its exact strengths, or visit our comparison hub to see head-to-head win rates against models like GPT-4o and Claude 3.5 Sonnet.

What does GPT-4o cost per million input and output tokens?

For OpenAI GPT-4o, this calculator uses $2.50 per 1M input tokens and $10.00 per 1M output tokens as baseline API pricing. Rates can vary by region, commitment tier, and batch endpoints—use the calculator above to stress-test your workload. When prompt caching applies, cached input is listed at about $1.250 per 1M tokens—confirm behavior in your provider console.

What context window does GPT-4o support?

GPT-4o is listed with a 128,000-token context window for a single request in our catalog. Very long prompts still increase cost linearly with tokens, so pair window size with caching and retrieval when possible.

Does GPT-4o support vision or multimodal inputs?

GPT-4o supports image inputs in this catalog; vision is priced separately from text tokens (see your provider for how images map to tokens).
