--- title: "Grok 4.6 AI model: facts and benchmarks | Kendr" canonical: "https://kendr.org/models/x-ai-grok-4-6" date_modified: "2026-08-12" profile_kind: "reference" --- # Grok 4.6 model profile Grok 4.6 is xAI's August 2026 flagship model for coding, long-running agents, research, information analysis, and interactive artifacts. Its official API profile documents 500,000 tokens of context, text and image input, text output, mandatory configurable reasoning, tool use, and structured outputs. Grok 4.6 is an independent knowledge profile. It does not claim that Kendr hosts the model, quote a Kendr customer price, promise API availability, or advertise a Kendr routing receipt. Grok 4.6 accepts text and image and returns text. The snapshot records agentic, code execution, coding, function calling, reasoning, structured output, text generation, vision, web search, and X search as capabilities or interfaces. The dated unit-price records list $0.005 per search for web_search_call, $0.005 per search for x_search_call, and $0.005 per request for code_execution_call. Each figure retains its billable dimension, variant, provider, source, and evidence date. The 2026-08-12 snapshot includes 10 publisher-reported launch results. Publisher-reported launch results are labeled and are not presented as Kendr measurements; scores from different suites are not treated as interchangeable. No comparable popularity rank or traffic share is present in the 2026-08-12 snapshot. No comparable routing rank or traffic-share observation is attached to this dated profile; missing adoption evidence is not estimated. Profile data was reviewed for the 2026-08-12 snapshot. Claims retain their source dates, and unavailable fields are shown as unavailable instead of estimated. ## Profile facts - **Profile type:** Model research profile - **Provider or publisher:** xAI - **Context window:** 500K - **Snapshot date:** 2026-08-12 - **Reference catalog ID:** x-ai/grok-4.6 ## Context, modalities, and identity Grok 4.6 accepts text and image and returns text.
