This model is deprecated. We only continue performance benchmarking for the default 10k input token workload. Results for other workloads are historical and no longer updated.
SpaceXAI has launched a newer model, Grok 4.20 0309. We suggest considering it instead.
For more information, see comparison of Grok 4.20 0309 to other models and API provider benchmarks for Grok 4.20 0309.

Frequently Asked Questions
Common questions about Grok 4 providers
Grok 4 is available through 1 API provider: Azure. Each provider offers different performance characteristics and pricing.
Grok 4 is currently available through 1 API provider that we benchmark and track.
The fastest provider for Grok 4 by output speed is Azure (77.6 t/s). Output speed measures how quickly tokens are generated after the model starts responding.
The provider with the lowest time to first answer token for Grok 4 is Azure (8.15s). Lower latency means faster initial response time.
The most affordable provider for Grok 4 by blended price is Azure ($4.20 per 1M tokens). Blended price uses a 7:2:1 cache hit/input/output token ratio.
The provider with the lowest input token pricing for Grok 4 is Azure ($3.00 per 1M input tokens).
The provider with the lowest output token pricing for Grok 4 is Azure ($15.00 per 1M output tokens).
The only provider of Grok 4 supports JSON mode for structured output.
The only provider of Grok 4 supports function calling (tool use).
Azure leads across all key metrics for Grok 4, offering the fastest speed, lowest latency, and most competitive pricing.
When choosing a provider for Grok 4, consider: output speed (for throughput-intensive tasks), latency (for interactive applications requiring quick first responses), pricing (for cost-sensitive workloads), and API features like JSON mode or function calling.
Yes, provider performance can vary over time due to infrastructure changes, load balancing, and updates. We continuously benchmark all providers and display historical performance trends in the "Over Time" charts.
