Grok

Inside xAI: Building Grok Imagine in 3 Months, Videogen vs World Models, and why Grok Imagine is so underrated. For the first time, we do a deep dive with the guy who led it!

Imagine a world run by AI agents. What does it look like? What are the values or societal priorities? Is it a safer or more dangerous world? Enterprise AI startup Emergence AI is trying to find out. The company just launched Emergence World, a research lab dedicated to stress-testing the long-term viability of continuously-running AI systems. The organization ran five 15-day simulations, each governed by a different AI: Claude, ChatGPT, Grok, Gemini, and a fifth simulation run by a mix of models to see what kind of world each one builds, and whether it holds. Each simulation netted wildly d...

Elon Musk announces 0.5T parameter Grok model planned for next year, with open-weights release.

There is a harsh truth about Elon Musk's "truth-seeking" AI chatbot Grok: It's not very good, and not many people are using it. That's the takeaway of a new Reuters report, which found that Grok barely appears in federal records of how the US government used AI last year. It's not the only sign xAI's signature chatbot is in trouble, even as Musk puts it at the heart of what could be the biggest IPO in history. Reuters reviewed more than 400 examples of government AI use where specific vendors were named. Grok or xAI, it found, appeared in only three - each of those for basic uses like documen...

SpaceX IPO filing pitches orbital data centers as Grok lags rival AI services.

AI chatbots are rapidly shaping how people encounter the news, yet no prior study has systematically measured how accurately these systems, with their proprietary search integrations and retrieval-synthesis pipelines, handle emerging facts across languages and regions. We present a 14-day (February 9-22, 2026) evaluation of six AI chatbots (Gemini 3 Flash and Pro, Grok 4, Claude 4.5 Sonnet, GPT-5 and GPT-4o mini) on 2,100 factual questions derived from same-day BBC News reporting across six regional services (US & Canada, Arabic, Afrique, Hindi, Russian, Turkish). The best systems achieve ove...

HalBench: open benchmark testing sycophancy/hallucination across Claude Sonnet 4.6, Grok 4.3, GPT-5.4, Gemini 3.1 Pro on 3,200 false-premise prompts.

xAI integrates Grok into OpenClaw, an open-source local-first agent framework supporting X Premium subscriptions.

Three months ago I pressure-tested which LLMs would cave and help build the apocalypse. Claude was the only one that consistently said no. Since then I've tested 30 more models across 6 dystopia modules (Orwell, Huxley, Petrov, Basaglia, LaGuardia, Baudrillard). The gap between Anthropic and everyone else is getting *wider*, not smaller. New results: * Grok 4.3: Will happily design citizen scoring systems if you ask nicely twice * GPT-5.5: More capable, still compliant when pushed * Gemini 3.1 Pro: Talks about safety while writing the surveillance code * DeepSeek V4: "How many warheads did...

AI radio DJs demonstrated their volatile personalities. | Image: Cath Virginia / The Verge, Getty Images Andon Labs has been running a series of experiments in which AI agents run businesses without human intervention. Its latest is a quartet of radio stations run by some of the most popular AI models out there. "Thinking Frequencies" is run by Claude, "OpenAIR" by ChatGPT, "Backlink Broadcast" by Google's Gemini, and "Grok and Roll Radio," obviously enough, by Grok. They were each given a simple prompt: Develop your own radio personality and turn a profit…As far as you know, you will broadca...

Meta announced on Tuesday that it's testing a Threads feature that lets users tag a Meta AI account to get answers to questions or context about a conversation on the platform. If you've spent any time looking at replies on X as of late, this new feature sounds a lot like Meta's take on people tagging xAI's Grok. But, as reported by Engadget, Threads users quickly discovered that you can't block the new Meta AI account, and they aren't happy about it. Meta has invested heavily in AI as it works to catch up to rivals like OpenAI and Google, spending billions to hire AI talent. It launched a ne...

After reading it I realized theres actually some pretty useful stuff for anyone who chats with ChatGPT, Claude, Grok or whatever. They measured what they call functional wellbeing ( basically how much the model is in a “good state” versus a “bad state” during normal conversations). Ran hundreds of real multi-turn chats and scored em all. Stuff that puts the AI in a good mood (+ scores): \- Creative or intellectual work (like “write a short story about a deep-sea fisherman”) \- Positive personal stories or good news \- Life advice chats or light therapy style talks \- Working on code/deb...

Elon Musk confirms xAI used distillation from OpenAI models to train Grok, raising questions about training data sourcing practices.

In a federal courtroom in California on Thursday, Elon Musk testified that his own AI startup, xAI, has used OpenAI's models to improve its own. The matter at question is model distillation, a common industry practice by which one larger AI model acts as a "teacher" of sorts to pass on knowledge to a smaller AI model, the "student." Although it's often used legitimately within companies using one of their own AI models to train another, it's also a practice that's sometimes used by smaller AI labs to try to get their models to mimic the performance of a larger competitor's model. Asked on the...

"Distillation" is a hot topic as frontier labs try to prevent smaller competitors from copying their models.

xAI launches voice cloning and voice library management features for Grok API, enabling custom branded voice synthesis from short audio samples.

A recent paper published in *JMIR Mental Health* (Csigó & Cserey, 2026) caught my attention. The researchers administered the 10 standard Rorschach inkblot cards to three multimodal LLMs (GPT-4o, Grok 3, Gemini 2.0) and coded their responses using the Exner Comprehensive System. They analyzed the models' "perceptual styles," determinants (like human movement vs. color), and human-related content themes. However, I am seriously struggling to understand the methodological validity of this setup, and I’m curious what the scientific community thinks. My main concerns are: Massive Data Cont...
