Early Thursday morning, Elon Musk posted a rapid-fire series of tweets pointing people toward Grok — xAI's AI assistant — capping the burst with a two-word post: 'As promised.' The phrasing signals that something specific was delivered, not just a routine nudge. Here's what we know so far and what it means if you haven't tried Grok yet.
What did Musk actually post?
Three tweets in the span of about four minutes. First, a direct 'Try Grok' with a link. Then a reply to a user, again: 'Try Grok.' Then the 'As promised' post, which carried the highest engagement of the three — over 2,500 likes and 633,000 views within the first hour. The 'As promised' framing is the key detail: it references a prior commitment, meaning something specific was unlocked or shipped, not just a general endorsement.
What is the 'promise' Musk is referring to?
The source material points to Grok 4.5 as the likely delivery. Background research confirms xAI has been working on a significant model update, and the timing of Musk's posts aligns with a new release or expanded access window. The 'As promised' language strongly implies this is a milestone that was publicly committed to — not a surprise drop. The exact scope of what's new in this version is still being confirmed as of this writing.
How does this connect to Tesla owners specifically?
Grok is already integrated into Tesla vehicles via the in-car voice assistant on supported hardware. When xAI ships a meaningful model upgrade, that improvement eventually flows into the in-car experience as well — better responses, more accurate information, and improved conversational context. It's worth checking whether your vehicle's Grok integration feels noticeably sharper in the coming days. For broader context on AI features in Tesla, see our FSD coverage.
Where can you actually try it?
Grok is accessible at grok.com, through the X app, and — for Tesla owners on supported vehicles — directly via the in-car voice interface. The links in Musk's tweets point to the web version. If you haven't used it recently, this appears to be a deliberate moment to re-engage users with a meaningfully updated product.
Should Tesla owners pay attention to this?
Yes — more than a typical AI product update. Tesla's in-car AI assistant runs on Grok, which means improvements to the underlying model have a direct downstream effect on the quality of voice interactions inside your car. When xAI levels up the model, Tesla owners eventually benefit without needing to do anything. Watching how the Grok web version performs today is a reasonable preview of where the in-car experience is heading.
The full details of what specifically shipped — whether it's a new model version, a capability expansion, or broader free-tier access — should become clearer as xAI's official channels confirm the release. What's clear from Musk's posts is that this was a planned delivery, not an offhand promotion.
