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

For OpenAI GPT-4o Mini, this calculator uses $0.15 per 1M input tokens and $0.60 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 $0.075 per 1M tokens—confirm behavior in your provider console.

What context window does GPT-4o Mini support?

GPT-4o Mini 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 Mini support vision or multimodal inputs?

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