Frequently Asked Questions
Common questions about Grok 3 providers
Grok 3 is available through 2 API providers: SpaceXAI Fast and Azure. Each provider offers different performance characteristics and pricing.
Grok 3 is currently available through 2 API providers that we benchmark and track.
The fastest provider for Grok 3 by output speed is SpaceXAI Fast (112.3 t/s). Output speed measures how quickly tokens are generated after the model starts responding.
The provider with the lowest time to first token for Grok 3 is SpaceXAI Fast (0.70s). Lower latency means faster initial response time.
The most affordable providers for Grok 3 by blended price are SpaceXAI Fast ($3.55 per 1M tokens) and Azure ($4.20 per 1M tokens). Blended price uses a 7:2:1 cache hit/input/output token ratio.
The providers with the lowest input token pricing for Grok 3 are Azure ($3.00 per 1M input tokens) and SpaceXAI Fast ($5.00 per 1M input tokens).
The providers with the lowest output token pricing for Grok 3 are Azure ($15.00 per 1M output tokens) and SpaceXAI Fast ($25.00 per 1M output tokens).
Prices for Grok 3 vary up to 1.2x across providers. The most affordable is SpaceXAI Fast at $3.55 per 1M tokens, while Azure charges $4.20 per 1M tokens.
1 of 2 providers support JSON mode for Grok 3: SpaceXAI Fast.
All 2 providers of Grok 3 support function calling (tool use).
SpaceXAI Fast leads across all key metrics for Grok 3, offering the fastest speed, lowest latency, and most competitive pricing.
When choosing a provider for Grok 3, 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.
