A few quick observations on Grok 4: 1) Hidden CoT with very little information in the reasoning trace 2) Uses web search a lot (not just searching X) 3) Have not seen it use code to run calculations or solve non-coding problems yet, generally less aggressive about tools than o3″” / X https://x.com/emollick/status/1943193331934052827
Among other things with the Grok 4 launch, it will be interesting to see how you demo a (presumably) very smart model. We are getting to the point where current AIs already do a lot of impressive things, so it is harder and harder to show to non-experts what a new model does.”” / X https://x.com/emollick/status/1943143689846448424

I can’t believe I’m saying it but “mechahitler” is the smallest problem:
* There is no system card, no information about any safety or dangerous capability evals.
* Unclear if any safety training was done. Model offers advice chemical weapons, drugs, or suicide methods.
* The “companion mode” takes the worst issues we currently have for emotional dependencies and tries to amplify them.

I suspect the next few weeks after Grok 4 follows the same pattern as Grok 3 xAI beats everyone to market with the first RonnaFLOP model.

The live tweaking of the system prompt for Grok to patch the MechaHitler problem is not a good sign the problem has been solved yet Prompts need to be tested just like any other product change, even more so, because stochastic systems and unpredictable context lead to cascades.”” / X https://x.com/emollick/status/1944426042145333410
The whole Grok situation (system prompt changes with values that conflict with post-training and pre-training values) is, oddly enough, similar to the reason the fictional AI HAL 9000 went insane, as was revealed in 2010, the sequel to 2001 https://x.com/emollick/status/1944381588357185542
This is not about competition. Every other frontier lab –

at the very least publishes a model card with some evaluations. Even DeepSeek R1, which can be easily jailbroken, at least sometimes requires jailbreak. (And unlike DeepSeek, Grok is not open sourcing their model.)

While xAI keeps doing these patches to Grok, I strongly suspect this is not going to work, the problem is deeper and the system prompt doesn’t provide enough control.
