Tokens per second

Throughput in tokens per second, derived from measured P50 latency. Higher is better; fluctuations track provider-side load.

Throughput (tokens / s)39 / avg 58
12912

Estimated from P50 latency × 200 output tokens — the absolute number depends on this assumption; the trend is what matters.

Availability

Availability

How often this model answers when we call it — measured across real API requests and live tests over the last 30 days. This is separate from quality: these numbers only tell you whether the model responds, not how good the answer is.

Technical details

Only live API calls and live-test requests count — internal probes and benchmark runs are excluded.

Calls with a custom API key (BYOK) are excluded: those failures are key-specific, not a sign of model downtime.

Failed calls are NOT included in quality scores — quality is measured on successful responses only. Availability and quality are independent signals.

Median response time (p50) across successful calls with a recorded duration. Outliers (very slow or very fast calls) pull the median less than the average.

Grok 4.6 debuts with strong performance across core benchmarks

Grok 4.6 enters the benchmark landscape as xAI's first evaluated model in this tracking window, establishing baseline performance metrics across multiple domains. The model demonstrates particularly strong performance in mathematical reasoning, achieving 89.4% on MATH-500 and 93.8% on GSM8K, placing it competitively among frontier models. Coding capabilities are robust with 86.5% on HumanEval and 79.6% on LiveCodeBench, indicating solid software engineering capabilities. Academic knowledge shows strength at 88.6% on MMLU-Pro, though GPQA performance at 56.4% suggests room for improvement in graduate-level science questions. Multimodal capabilities are present with 74.3% on MMMU, establishing vision-language integration. The model supports JSON output, tool use, and reasoning modes, providing developers with flexible interaction patterns. With a 128K token context window, Grok 4.6 handles substantial documents and conversations. As a baseline entry, these metrics establish xAI's position in the competitive landscape, showing particular strength in mathematical and coding tasks while maintaining competent performance across general knowledge domains. Future benchmark windows will reveal how the model evolves relative to this initial showing.
