Zeptix supports xAI's AI models as of today. You can now switch your chatbots to grok-4.3 and the brand-new coding model Grok Build 0.1 — right in your dashboard's model picker.

What's new

grok-4.3 — on every plan. xAI's flagship for general-purpose chat: strong reasoning, reliable tool calling and a low hallucination rate. Available from the Starter plan.
Grok Build 0.1 — from Pro. xAI's model trained for agentic coding. Optimized for web development, debugging and structured outputs — a fast, affordable choice for bots that work with code.

How to activate a model

Open your dashboard and pick the bot you want to adjust.
Go to the Models tab and choose the Grok model you want.
Save — done. The next chat runs on the new model.

Models your current plan doesn't cover are shown greyed out with the matching plan hint. An upgrade unlocks them instantly.

Why we're adding Grok

More choice means the right model for the right job. Grok Build 0.1 complements our coding-oriented options, while grok-4.3 is a strong, fast general-purpose alternative. As always, the model choice stays with you — and behind the scenes our fallback chain makes sure your bot keeps answering, even if a provider hiccups.

For an in-depth take on what Grok Build 0.1 can do technically and when the switch is worth it, see the blog: Grok Build 0.1 — the new coding model at a glance.
