Grok 4 API pricing

A typical request of 5,000 input tokens and 1,500 output tokens costs about $0.037 at list price. A thousand of those requests costs about $37.50.

Model usage is drawn from your balance at the upstream list price of each model. Figures above are indicative and exclude any plan fee; the console is the source of truth for live pricing.

Where Grok 4 fits

Grok 4 combines a 256K context window with $3.00 per 1M input and $15.00 per 1M output tokens, the same price band as Claude Sonnet 4.5.

Pick it when

• You want to compare vendors on the same task and the same budget rather than only on price.
• You need a 256K window - larger than the Anthropic models, smaller than the 1M options.
• Your workload mixes long-context reading with a moderate amount of generation.

What to watch

• At the same price as Sonnet 4.5 the choice comes down to output quality and tool behaviour, so test both on your own cases.
• The cheaper Grok 4 Fast sits alongside it in the catalogue when throughput matters more than depth.

Best for: Vendor comparison runs, 256K-context analysis and workloads already built around xAI output.

How to call Grok 4 through the gateway

Point your client at https://api.quickrouter.homes/v1 with a QuickRouter key and pass grok-4 as the model name. Nothing else in an OpenAI-style client changes.

curl https://api.quickrouter.homes/v1/chat/completions \
  -H "Authorization: Bearer sk-qr-your-key" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "grok-4",
    "messages": [{"role": "user", "content": "Hello"}]
  }'

The console lists the model ids your key can reach - use the id exactly as it appears there.
