Where this family fits.
Turning reasoning off or adjusting it down on Grok 4.3 for lighter responses
Keeping some reasoning effort active by default on Grok 4.5, which has no off setting
Using Grok 4.6 when a fixed, model-managed reasoning behavior is acceptable
Requests that combine text with an uploaded screenshot, diagram, or photo on any Grok variant
What not to assume.
All three Grok variants require Paid-model access
Grok 4.6 uses a fixed reasoning behavior with no selectable effort preset
Grok 4.5 has no off or none reasoning preset; some reasoning effort is always applied
Vizify sends each request to one selected Grok variant rather than running several at once
Three generations, one Paid tier
Vizify currently exposes three Grok chat variants — 4.3, 4.5, and 4.6 — and all three are listed in the Paid catalog. There is no Basic-tier Grok variant in the current app profile.
Reasoning control differs by generation
Grok 4.3 exposes an adjustable reasoning effort control that includes an off setting alongside low, medium, and high. Grok 4.5 also exposes an adjustable effort control, but it has no off setting: some reasoning effort is always applied. Grok 4.6 currently uses a fixed, model-managed reasoning behavior with no selectable preset. Check the model picker in Vizify for the control that applies to the variant you choose.
Text and image input across the family
Grok 4.3, Grok 4.5, and Grok 4.6 are all included in the Vizify vision list, so the customer App can pass a supported image upload along with the request after it validates file and account requirements. This page does not imply that every chat model in the broader Vizify catalog shares the same input support.
Capability review
Availability, tier, and input support were checked against the Vizify repository and app profile on 2026-08-16. Search demand for these specific models has not been validated: the most recent keyword research package predates them, so this page is published on capability evidence alone and does not imply demand-backed priority. Provider benchmarks, external release status, pricing, and performance rankings are outside this page’s factual contract.
FAQ
Questions about xAI Grok models in Vizify.
Which xAI Grok variants are available in Vizify?
The current Vizify catalog includes three Grok chat variants: Grok 4.3, Grok 4.5, and Grok 4.6. All three are listed in the Paid tier.
Which Grok model does this page open?
The primary action opens Vizify with Grok 4.6 as a one-time launch selection. The App validates that model against its live catalog before use.
Is Grok 4.6 the default model in Vizify?
No. The account-wide default chat model in the current app profile is GPT-5.4 Mini. Selecting Grok 4.6 from this page is an explicit one-time launch hint, not a change to your account default.
Can Grok models analyze an uploaded image in Vizify?
Yes. Grok 4.3, Grok 4.5, and Grok 4.6 are all currently marked for text and image input in the Vizify app profile.
Can I turn reasoning off on Grok in Vizify?
Only on Grok 4.3, which offers an off setting alongside low, medium, and high effort. Grok 4.5 always applies some reasoning effort and has no off setting. Grok 4.6 uses a fixed, model-managed reasoning behavior that is not exposed as a selectable preset.
Do all three Grok variants require Paid-model access?
Yes. Grok 4.3, Grok 4.5, and Grok 4.6 are all in Vizify's Paid tier, so the App checks current Paid-model entitlement before sending a request.
Does Vizify run Grok 4.3, 4.5, and 4.6 on the same request?
No. Vizify selects one model for each request. You can switch Grok variants between requests, but this page does not promise parallel answers or automatic comparison.
