xAI models and prices
21 models, 17 with a published price · released 2026-01-29 to 2026-08-12.
You can buy from xAI directly, or from 2 other hosts
We hold offerings sold by xAI itself as well as by independent hosts. Buying direct is not automatically the cheapest route, and it is not automatically the same product either — hosts differ on quantisation, served context window and rate limits.

Measured quality across xAI models
Our own probe suite at temperature 0, scored by deterministic checks — no LLM judge and no vendor claim. Measured on request, so most of the catalog is unscored; a blank is not measured, never a low score. Confidence falls when probes could not be read, which happens on models that answer in a hidden reasoning channel.
| Model | Score | Tier | Ranking probes | Confidence |
|---|---|---|---|---|
| Grok 4.3 | 100/100 | frontier | 5/5 | 1 |
Who sells xAI models
Offering rows per seller across this vendor's models. A seller appearing many times serves many of the models, not the same one repeatedly.

Jobs these models do
Comparison on each model page is restricted to models doing the same job — a price difference between two different jobs is arithmetic rather than advice.

One API for every xAI model
VernaOne fronts the sellers on this page behind a single interface, so switching model or host is a config change — with automatic fallback if quality or latency regresses.

Newest first, priced or not. A model with no price is a fact about what its sellers publish, not a gap we are hiding.

Frequently asked
How many models does xAI have?
We track 21 xAI models across 4 categories, 17 of them with a published price. The list is rebuilt from provider APIs, the vendor's own docs and the weights registry rather than maintained by hand, so new releases appear without us writing about them.
Can I buy xAI models directly from xAI?
Yes — we hold offerings sold by xAI itself (as xai), alongside 2 other hosts. Buying direct is not automatically cheapest: each model page lists every seller with its price and the evidence behind it.
Are xAI models open weights?
None of the xAI models we track publish weights, so they can only be used through an API.
