Frequently asked questions
How much does GPT-4 Turbo cost?
GPT-4 Turbo costs $10.00 per 1M input tokens and $30.00 per 1M output tokens, sourced from openai. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.
What is the context window of GPT-4 Turbo?
GPT-4 Turbo has a context window of 128K tokens, with a max output of 4K tokens per reply. This is the total combined size of prompt + completion.
Does GPT-4 Turbo support tool calling?
Yes. GPT-4 Turbo supports tool calling (function calling). This makes it suitable for production agent and automation workloads where the model has to invoke external functions reliably.
Does GPT-4 Turbo support structured output / JSON mode?
No. GPT-4 Turbo does not support structured output / JSON-schema-constrained decoding. If your workflow requires it, look at the /capabilities/structured-output list for alternatives.
Can GPT-4 Turbo accept image input?
Yes. GPT-4 Turbo accepts both text and image input. Vision pricing per image is usually billed on top of the regular token rate — check OpenAI's docs for the exact rule.
Is GPT-4 Turbo open-weight?
No. GPT-4 Turbo is a proprietary model — only OpenAI (and any approved hosting partners) can serve it. The pricing above reflects the cheapest API access.
What are the best alternatives to GPT-4 Turbo?
If GPT-4 Turbo doesn't fit, consider GPT OSS 120B, GPT OSS 20B, GPT-5.2. Each one targets the same use case — see the Related links below for direct head-to-head pages.
Where does this data come from?
All numbers come from the public models.dev API and are normalised into a single canonical model record. We re-pull daily and write any changes (price, context, capability) to the /changelog page.
