Frequently asked questions
What is the benchmark price for the Grok 4.5 API proxy?
The panel benchmark price for grok-4.5 is $2 for input and $6 for output per 1 million tokens, with a benchmark cache-hit price of $0.5 / 1 million tokens. The final billed price must also be multiplied by the multiplier for the user's group.
Why does the actual price of Grok 4.5 differ from the benchmark price?
The actual price equals the benchmark price multiplied by the multiplier for the user's group. Confirm the account group in the platform panel first, then reconcile the billing statement against input, output, and cache-hit usage.
Which models does the Grok 4.5 API proxy support?
The platform lists a total of 452 models for sale, and grok-4.5 is included in the list. The provided table shows only the 150 models with the highest call volumes; the 302 models not shown cannot be considered unsupported based on that omission alone.
What is the context length of grok-4.5?
The context length of grok-4.5 remains to be verified through testing. Before making calls, rely on the actual model configuration and test results shown in the platform panel.
How do I call grok-4.5?
When calling grok-4.5, obtain the request endpoint, authentication credentials, and currently supported request format from the platform panel, then make a minimal request using the model name grok-4.5 for verification. Replace API_URL and API_KEY in the page example with the actual values provided by the panel.
What limitations apply when calling Grok 4.5 through a proxy?
Calling through a proxy adds an extra network hop, so actual latency, error-handling paths, and service status need to be verified independently. New official models or features may also experience listing or rollout delays on the proxy side.
