It should be noted that this is only the $300/month "heavy" variant. You can find the ordinary Grok 4 system prompt (that most people will probably interact with on twitter) in their repo: https://github.com/xai-org/grok-prompts/blob/main/ask_grok_s...
That isn't synced with what's in prod. E.g the system prompt changes that xai said were made during the "mechahitler" phase did not show up in that repo.
This seems similar to the situation where x.com claimed that their ML algo was in github, but it turned out to be some subset of it that was frozen in time and not synced to what's used in prod.
We have evidence it is NOT the actual prompt - xAI posted snippets of the actual prompt here that never showed up in that GitHub repo: https://x.com/grok/status/1943916982694555982
The GitHub repo appears to be updated manually whenever they remember to do it though. I think they would benefit from automating that process.
Like with X, it has a GitHub repo so it is transparent! It's what's all over the internet that it's trained on that made it randomly obsessed with white genocide on South Africa and try to work that into every conversation that one week
