Grok
xAI's proprietary family for reasoning, tool use, multimodal input, and live-data workflows.
Family strengths
Managed models include tool and real-time information paths. Provides general, reasoning, coding, and multimodal variants.
Family limitations
Closed weights and provider-controlled data/tool access. Observed quality depends on the exact model and enabled tools.
Verify the exact version before choosing: capabilities, price, context limits, latency, tools, and regional availability can differ by provider access path.
