How much do GPT-4o or GPT-4o mini cost per month?

For an example workload of 20 million input tokens and 5 million output tokens per month: GPT-4o: $100. GPT-4o mini: $6.00. These are token-only estimates using the displayed rates, without caching discounts, additional tool charges or taxes. Actual bills depend on usage and endpoint pricing.

Which has a larger context window: GPT-4o or GPT-4o mini?

GPT-4o: 128K tokens of context; maximum output 16K tokens. GPT-4o mini: 128K tokens of context; maximum output 16K tokens. Context capacity and maximum output are separate limits. A larger context window allows more material in a request but does not guarantee more accurate answers.

Which is better for coding: GPT-4o or GPT-4o mini?

GPT-4o: Artificial Analysis SciCode not listed. GPT-4o mini: Artificial Analysis SciCode not listed. Compare coding results within the same evaluation, then test representative tasks from your own codebase. A missing score is not a zero, and a single benchmark does not establish the best model for every programming task.

How do Arena Elo, DesignArena, Intelligence Index and MMLU-Pro differ?

These evaluations measure different tasks and use different scales. Arena Elo and DesignArena ratings must remain separate, as must Artificial Analysis Intelligence Index and MMLU-Pro. Compare models within the same evaluation rather than combining scores. Missing results are marked Not listed, not treated as measured zeroes.

Which responds faster: GPT-4o or GPT-4o mini?

GPT-4o: Artificial Analysis output speed 145 tokens/s; time to first token 0.84 seconds. GPT-4o mini: Artificial Analysis output speed 89 tokens/s; time to first token 0.88 seconds. Output speed measures generation throughput, while time to first token measures the initial wait. Real-world latency also depends on the API provider, request size and load; missing measurements cannot establish a speed winner.

Do GPT-4o or GPT-4o mini support images, audio or video?

GPT-4o: listed input formats: text, image, file; output formats: text. GPT-4o mini: listed input formats: text, image, file; output formats: text. Input and output support are different capabilities: accepting an image does not mean a model generates images. Confirm formats and file limits for the endpoint you plan to use.

Can prompt caching reduce the cost of GPT-4o or GPT-4o mini?

GPT-4o: cached input price $1.25 per million tokens. GPT-4o mini: cached input price $0.07 per million tokens. Caching may reduce charges for eligible repeated input when supported by the endpoint. A listed cached rate does not guarantee every request qualifies; cache duration, minimum token counts and any write charges depend on the provider.

Are GPT-4o or GPT-4o mini available through an API?

GPT-4o: catalog status active; API identifier gpt-4o; listed API hosts Azure, OpenAI. GPT-4o mini: catalog status active; API identifier gpt-4o-mini; listed API hosts Azure, OpenAI, Azure. Catalog status is not a live availability check. Before integrating, verify the provider's documentation, endpoint access, rate limits, regional availability and data-handling terms.
