Our recently completed Grok V9 1.5T run is looking great and that is before Cursor data is added in supplemental training

@elonmusk · 15 mai 2026
The version numbers are a little confusing and deserve some explanation.
Internally, we are working on version 9 of our new foundation model, which is 1.5T params. This is substantially better in every way than v8: data curation, training recipe, size, etc. It is also optimized to run on a Blackwells.
The public facing v4.2 is based on foundation model v8, trained on Hoppers, with significant shortfalls in training data quality, comprehensiveness and proportionality. It is also only 0.5T in size.
The difference between Grok foundation model 8 and 9 is gigantic.

Impressions so far: Grok Build interface is actually really nice.
Now as soon as xAI has a SOTA model, it could very well become competitive with Codex / Claude Code overnight

The goal of the 𝕏 algorithm is simple: show each user the content they are most likely to find interesting, limited only by the laws within a given jurisdiction. No thumb on the scale.
Doesn’t mean we achieve the goal, but that is what I tell the team.

How to tell what phase of life a girl is in:
Posting thirst traps = recently single
Posting 5 stories a day and scrolling through so see if he saw it = she’s dating a guy who doesn’t like her
She suddenly starts posting home cooked meals, sourdough, and little farmer’s market

So Grok CLI is cool and I'm stoked about the discount for SuperGrok Heavy.
But using 3.44% of my credits answering "what can you do?" This is not so solid.
Hoping that's a 5hr window, having some trouble finding rate limit info!
