Frequently asked questions
How much does Grok 3 cost?
Grok 3 costs $3.00 per 1M input tokens and $15.00 per 1M output tokens, sourced from xai. Cache reads, audio tokens and >200K-context tiers (where applicable) are listed in the Pricing detail block above.
What is the context window of Grok 3?
Grok 3 has a context window of 131K tokens, with a max output of 8K tokens per reply. This is the total combined size of prompt + completion.
Does Grok 3 support tool calling?
Yes. Grok 3 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 Grok 3 support structured output / JSON mode?
Support for structured output / JSON-schema-constrained decoding is not reported for Grok 3 in our data source. Verify with xAI's official documentation before relying on it in production.
Can Grok 3 accept image input?
No. Grok 3 only accepts text as input. If you need image input, see our /capabilities/vision list for current vision-capable models.
Is Grok 3 open-weight?
No. Grok 3 is a proprietary model — only xAI (and any approved hosting partners) can serve it. The pricing above reflects the cheapest API access.
What are the best alternatives to Grok 3?
If Grok 3 doesn't fit, consider Grok Code Fast 1, Grok 4.1 Fast (Non-Reasoning), Grok 4. 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.
