GPT-4o 20240513

Compare gpt-4o-2024-05-13 against models of similar capability and pricing on your actual workload. Evaluate latency, output quality, instruction following, and cost per task. Run side-by-side tests with your own prompts — the best model depends on your specific use case, not just benchmark scores.

gpt-4o-2024-05-13 supports up to 16384 output tokens per request. Plan your prompts to stay within this limit, and use the max_tokens or max_completion_tokens parameter to control output length.

gpt-4o-2024-05-13 supports prompt caching, which can significantly reduce costs for repeated prompts with shared prefixes. The cache read price is substantially lower than the standard input price. Check the current pricing page for the exact cache hit discount ratio for gpt-4o-2024-05-13.

GPT-4o is billed per use and the record publishes no free-tier allowance. The current published rates are input $5.0000 per 1M tokens and output $15.0000 per 1M tokens. Trial credit or promotional quota is tied to your account rather than to the model, so check the console before planning around a free tier.

The GPT-4o record lists prompt caching as a supported feature but publishes no cache-read rate, so cached-prefix billing is not part of the current pricing. Treat repeated prefixes as fresh input when you size the workload, and confirm the rate with the provider before designing for a cache saving.

For gpt-4o-2024-05-13, set the max_tokens or max_completion_tokens parameter to control spending per call. Start with a budget aligned to your typical response length and increase only when longer outputs are genuinely needed. Monitor token usage in the API response headers to tune your budget over time.
