First off, it is good to see a postmortem from xAI, a step towards much needed transparency. Second, an example of how even small changes to system prompts, interacting with users and outside context in the wild, can lead to unexpected outcomes in advanced LLMs.

Grok 4 System Prompt Leakage and Monitoring Protection
By

Sometimes grok 4 heavy starts showing the system prompt, but then stops after a few tokens, such as in the case below. It appears there is a monitoring model on top explicitly trying to protect the system prompt.

Grok’s Elon Mode: Analyzing Model Training Behaviors
By
–
I can't figure out what specific topics trigger grok's "what does elon think" mode. It does seem like this behavior might have been explicitly trained into the model, in a subset of the training data, based on grok's observed behavior.

Yeah one shot, tested that prompt once, hit record and it did that lol

Prompt Engineering Evolution: Context Engineering and Intent Encoding in 2025
By
–
i think Prompt Engineering is "growing up" in two different ways in 2025. the first is "Context Engineering", which is well covered by @dexhorthy
's talk (now >100k views!) but Prompts = Intent + Context and as @sgrove points out the task of encoding intents/goals/principles -
