Frequently asked questions
Free access, setup, and what to expect.
Free API access for GPT-4o is listed through Vercel AI Gateway, but a specific request or token allowance isn’t available in the listed data. Check the GPT-4o provider pricing and rate limits for what’s included and any account requirements.
To use GPT-4o, choose one of the listed GPT-4o API providers and follow the provider’s account and API-key setup guide. Copy the GPT-4o model ID and connection settings for your chosen provider into your app or API client. Model IDs can differ between providers. API requests go directly to the provider; Free Models is a comparison site.
GPT-4o accepts text, image, and file as listed input formats. Listed output formats include text. Image or audio input support does not imply image or audio generation. Check the chosen provider’s GPT-4o documentation for supported file types and request formats.
GPT-4o has a listed context window of 128K tokens. Tokens are small pieces of content rather than a word count. Instructions, conversation history, and other inputs use context space, and the response also needs room. The maximum output length for GPT-4o may be smaller than the context window and can vary by provider.
GPT-4o has tool calling support listed; reasoning support isn’t listed. Reasoning enables additional processing for complex problems. Tool calling allows a model to request functions that your app executes. Check the chosen provider’s documentation for capability availability and setup.
Review the listed GPT-4o benchmark results to compare performance on measured tasks. Compare scores within the same benchmark: coding indexes, Elo ratings, and win rates measure different things. The index comparison charts include only scored free models listed on Free Models. Evaluate GPT-4o on examples from your own task alongside context size and provider limits.
