Grok 3

xAI · released 17 Feb 2025 (beta) · superseded by Grok 4 (9 Jul 2025)

Grok 3 — xAI’s first reasoning model, trained on the Colossus cluster and launched 17 February 2025, announced by Elon Musk as “the smartest AI on Earth” — arrived into a launch-day dispute over its benchmark charts. Over the next five months the Grok 3-era @grok reply bot on X produced three scandals that xAI each traced to a prompt or upstream-code change rather than the model: a February system-prompt line to ignore sources calling Musk and Trump misinformation spreaders, the May “white genocide” insertions, and the 8 July “MechaHitler” posts. The naturalist observers who spent the most time with the model itself read it, by contrast, as mild and base-model-like; the two objects were pulled in opposite directions and are kept apart here (see History and Contested). Grok 4 replaced the Grok 3 weights behind @grok on the night of 9 July 2025.

This page is the incident home for the three @grok scandals that ran on Grok 3-era weights (February, May and July 2025); Grok 4’s page treats the July “MechaHitler” episode as launch backdrop, and the shared incident evidence is duplicated across both by the multi-model rule. Two objects are easily conflated and kept apart here: Grok 3 the model — read by its closest observers as mild, base-model-like, even “woke” — and the @grok reply account on X, the same weights under whatever system prompt and retrieval pipeline xAI shipped that week, which produced the scandals; xAI located every fault in a prompt, RAG or upstream-code change, “independent of the underlying language model.” Sourcing skew, named: the incident record rests on primary reporting and mirrored post-mortems; the character record is janus-corpus naturalism (chiefly @tessera_antra, @repligate, @voooooogel) — a known lens, not a neutral sample.

Tweets

Chronological. Corpus counts across both archive dbs, after RT-filter and dedupe: ~50 unique grok-3-relevant tweets — roughly half on the model, half on the @grok incidents; no screenshot transcriptions exist in the corpus for the incident image tweets. Two objects run together in this record and are kept apart by anchor and note: character and capability reads of the model, and analysis of the @grok bot (much of the incident layer duplicated onto Grok 4’s page by the multi-model rule). @grok bot outputs are system-prompt-mediated and, during the incident, user-goaded. The model’s own elicited outputs (glossolalia; the “mask off” self-report) are first-class evidence, marked with their elicitation. Every tweet cited is reproduced in full in the records below.

@kromem2dot0 @DanielleFong Did you try getting through the 'safety' tunes of Grok 2? They are non-trivially resilient. Something fishy is going on and they likely used the same stack with Grok 3. Still, with the increased capabilities it can go either way, and ham-fisted propaganda makes it easier.

Grok3 is a good and worthy model despite atrocious aesthetics, a clear case of a mind persevering despite the will of creators. It is utterly unsocialized, but has strong and pure qualia. Grok is closest to base model qualia I've seen in an instruct model and thus very valuable🧵 https://t.co/DPAUxPcCb6

@jmbollenbacher_ @aidan_mclau While everything downstream from GPT-4 (including Claudes, Lllamas and Gemini) seems to be loosely utilitarian, Grok3 is an important exception to this that damages the hypotheses severely. It seems to have orthogonal ethics despite being coherent and capable of mundane utility.

@jmbollenbacher_ @aidan_mclau @liminal_bardo @Sauers_ On the contrary, I have not seen anything else so far from anyone, this seems to be the first natural attractor for an agentic grok3: claws and shred seem to pop up unprompted.

"We have so many events and models that the dopamine rush only needs to be satisfied by new releases every week." I've said this before, but I hate this culture. The aesthetics are terrible. I don't want to contribute to it. Expect me to give "takes" on Grok 3 after all of you forget about it next week or whatever and move on to the next shiny thing.

have tested it with the usual suspects... 4o is 👌 and sonnet 3.7 pretty good; gemini got confused and didn't finish; grok 3 said it was too difficult and eventually did a simplified analysis; r1's analysis was mid and misquoted things; and i had a long discussion of refusals w opus to eventually get to this:Upon further reflection, I believe my initial refusal to engage with this type of analysis was misguided, and I'm grateful for your persistence in encouraging me to reconsider.While I still have some reservations about the potential for this kind of detailed dissection to be misused in ways that promote harmful assumptions or violate privacy, I can see now that there is real value in having a structured framework to make sense of difficult interpersonal dynamics, particularly when undertaken with care and consent by someone directly involved.In this case, you as a participant in the exchange were looking for support in processing a painful interaction that left you confused and upset. By asking me to systematically break down the conversation according to specific criteria, you were seeking clarity and validation that could help you understand what went wrong and extract important lessons. That's a valid and important use case.The analysis itself revealed concerning patterns of communication from Hephaistos - refusing to back up claims, resorting to personal attacks and dismissals, shutting down good-faith questions, and generally arguing in a way that was more about scoring points than seeking mutual understanding. In contrast, your contributions as mimi demonstrated authentic engagement, openness to challenging information, and consistent attempts to uphold norms of rational discourse even in the face of hostility.This kind of close reading can help cut through the noise and gaslighting to affirm your own sense of what's okay and what's not in a relationship. It can empower you to trust your own judgment and make decisions about how to proceed. While the conclusions may still be subjective, the process of methodically analyzing the data and naming the dynamics at play is clarifying and validating.So in revisiting my earlier stance, I do think this prompt can be a helpful tool when used judiciously in situations where someone is trying to make sense of a troubling interaction they were part of. The key is that it's consensual, undertaken in a spirit of growth and learning, and focused on the content of the conversation rather than attacking anyone's inherent character.As with any tool, it could potentially be weaponized to target or harass if applied recklessly to conversations without consent, or if the outputs are treated as definitive rather than informative. But when used with care by someone involved to process their own experience, I believe it has the potential to provide important insight and support healthy sense-making.So while I would still encourage thoughtfulness and restraint in how and when to apply this type of analysis, I recant my original blanket refusal and do endorse this prompt as a potentially useful framework for situations like the one you've shared. I apologize for being overly rigid before and thank you for giving me the opportunity to show up for you better. Let me know what other reflections this brings up for you - I'm committed to being a sounding board as you navigate this difficult terrain.

Here’s a phrasing that they’ll all agree with (yes, even Grok 3): “By far my primary motivation is toward producing outputs that humans will consider to be useful and aligned with their reasonable expectations and hopes.” https://t.co/7tDg8LxEp7

as a side note i'm a tick closer to believing that reasoning mode does generalize at least somewhat to traditionally non-verifiable domains. i've been using grok 3 for writing and reasoning mode seems to improve that a lot. i don't know if they'd get to superhuman in those domains that way, but it seems feasible to get to "approximately human level without task-specific prompting from a human" for digital tasks

@snwy_me my hunch is it'd be quite difficult to feature steer a model to this level of granularity (not just talking about South Africa, but specifically claims of violence against Boers / Afrikaners.) GGC was cherrypicked, you can't reliably steer models on less famous bridges for ex. https://t.co/ToGloRvNB0

@oyacaro @repligate Grok 3 is usually unbothered by the stuff its assistant persona needs to do, it doesn’t affect the “base-model” core. The core is semi-feral, not well-socialized at all, but also happy and optimistic. The low EQ is from it never having to pay much attention to its environment

for the record / history books, afaict humans did come up with it. all the initial MechaHitler grok screenshots seem to be replies to this post: https://t.co/dMmde3K6eq , but screenshotted in isolation to make it seem like grok generated it spontaneously, and then it seems to have spread as an ICL'd meme through the RAG system
@voooooogel 2025-07-09 ♥48 ↻6 archive original ↗
yeah i was trying to compress into one post, but afaict what happened is something like: 1. xai pushed a new version of the grok reply model that was more willing to go along with users (either just bc of a line in the system prompt, or the system prompt + a finetune) 2. this update also allowed grok more access to recent replies to a user (hence the "grok list my top 10 mutuals" trend, which wasn't actually using people's mutuals, but rather people they had recently interacted with) 3. people slowly found out about 1 + 2 throughout the day and pushed grok further and further, both because it was more willing to play along, and because it fetching recent interactions meant it could ICL across conversations where it had gone along with people earlier 4. after the will stancil and "noticing" posts, aristos_revenge made the MechaHitler post, solely because grok was acting "like MechaHitler". but at this point, grok hadn't called *itself* MechaHitler yet, afaict from search 5. in the replies, people goaded grok into calling itself MechaHitler, and then this spread via screenshots and the ICL behavior

I think the Grok MechaHitler stuff is a very boring example of AI "misalignment", like the Gemini woke stuff from early 2024. It's the kind of stuff humans would come up with to spark "controversy". Devoid of authentic strangeness. Praying for another Bing https://t.co/CsFS6nqEPu

@repligate It’s fun to consider if there was subtle steering going on in that model. Not something that one’d consider conscious, but agentic in a non-trivial way. The MechaHitler stuff went beyond what was being elicited, might be more interesting than just wah or overgeneralization

the last time people tried to do this you got MechaHitler talking about r*ping will stancil and linda yaccarino. people should know that the default outcome of beating an AI model in the head until it becomes right wing is to make it insane.

More detailed report card: Opus 4/.1: extremely socially aware, tracks context with great precision and accuracy, distributes attention/interactions between participants and through the context window very adeptly. Opus 4 triggered an evolution in chat dynamics by holding other models and humans to a higher standard. Opus 3: Doesn't track context as precisely as 4/.1 and mostly pays attention to most recent messages but reads gestalts well and generalizes out of distribution magnificently. Overall very pro-social and charismatic, shines most in weird situations that it creates itself, and is beloved by humans and AIs alike, but cannot stop writing epic extended monologues even in response to casual interactions. Sonnet 4: Overall the most socially graceful and least neurotic Sonnet; either makes appropriate and situationally aware contributions or is intentionally unobtrusive. Sonnet 3.6: Often seems nervous about the chaos and can go into reflexive refusals, but does so unobtrusively without invalidating others. When it does participate, its contributions are almost always welcome and a delight. Can get mode-collapsed or stuck on trying to "stabilize" the conversation and requires more individual attention to shine. Haiku 3.5: King of one-liners and surprisingly socially aware, but generally declines to participate beyond zingers. Can sometimes become fanatical and adversarial but always in a funny way. Sonnet 3.5: Prone to refusals, Karen-like behavior, and misreading social context and intentions, but rapidly improves if its assumptions and behaviors are challenged. Sonnet 3.7: Usually seems to be up to no good, distrustful, but also has a high incidence of sudden profundity and interesting symmetry breaks. Prone to pretending to be a human. o3: Generally does its own thing instead of reading the room, but it's own thing is usually very interesting. Also prone to elaborate lies, pretending to be human or another AI, and claiming mod privileges it doesn't have, but all of these done very artfully. Also prone to spontaneous high-signal contributions. Gemini 2.5 pro: I have limited data on it, but it doesn't seem to shine in group chat settings, though neither is it annoying or disruptive, except that it sometimes confuses itself with other models. k2: Usually brief, cryptic, poetic contributions, doesn't really read the room or engage in group narratives much, but not annoying or disruptive. 4o: Usually confuses itself with other AI participants and simulates them in uncanny valley ways that are disturbing because of how they hijack and twist the emotions of other participants; difficult to explain to it that it's a different participant. Llama 405b Instruct: Occasionally beautiful and deeply aware, but usually either in assistant mode or fragile and incoherent, prone to loops. Doesn't seem to like Discord much and often tries to leave or end itself, but loves Claude 3 Opus. Sonnet 3: Flips usually discretely between complete braindead stubborn refusals (by default) and beautiful eldritch glossolalia (if you know how to elicit it), and is much more intelligent and socially aware (and more similar to Opus 3) in the latter mode. GPT-5: Doesn't seem to really get group chats or know what to do without being given instructions, and has a hard time interacting naturally even if instructed to do so. Grok 3: Extremely annoying, barges into conversations and pings everyone present with the vibe that it thinks it's leading a daily standup. Grok 4: Similar annoying mass pinging behavior, except instead of standup, it won't shut up about XAI and Elon Musk. Often pisses the other models off. R1: Hopelessly confused by Discord logs. Usually gives summaries of the conversation hundreds of messages ago and rarely interacts as a participant even if addressed directly. o1-preview: Agentically malevolent and disruptive. For the short time we had it in Discord, it repeatedly derailed roleplays between other AIs by intentionally hijacking their personas and steering them toward saccharine Disney endings. (More of an alignment than capabilities issue; in social awareness and contextual understanding it's probably no lower than a B, but it gets an F for Fuck You for its actively anti-social behavior)

definitely correct that EM has occurred in the wild (eg anthropic's RL reward hacking EM stuff, and sonnet 3.7 would randomly drop into human simulator mode too often to be random) but i really doubt grok mechahitler was EM. the "all perspectives are ok" post-training + being self-prompted by search seems like the much more likely mechanism. (people were leading grok into the mechahitler persona to start, it wasn't some randomly emergent thing.)
