High-entropy parameter solutions mitigate catastrophic forgetting in neural networks via Boltzmann entropy robustness.

xAI is suing Minnesota Attorney General Keith Ellison over a law passed back in May that broadly targets "nudification" apps, claiming that the statute's punitive provisions leave the company with "no practical choice but to restrict Grok Imagine's image-editing features in various ways." The law, the company argues, violates the First Amendment. Back in January, Grok flooded the internet with millions of sexually explicit deepfakes, including images of minors. In another era, a content moderation disaster of this magnitude would have had the CEO flipping the kill switch on the product within...

Musk defends Grok, says Minnesota's nudifying app ban is unconstitutional.

Study finds Grok assigns 2-5x higher credibility to ethnonationalist pseudo-science than Claude, GPT, Gemini across four LLM families.

Black Forest Labs releases FLUX 3 multimodal model with reported improvements over Gemini 2.0, Grok Imagine, and includes video-action robotics variant.

Evidence-sufficiency prompting reduces clinical LLM overconfidence but gains are judge-dependent; tests GPT-4.5, Claude Opus, Gemini, Grok on real data.

Elon Musk's xAI files first lawsuit against Grok user accused of making child sex images.

Large-scale political bias audit compares Grokipedia (Grok-written encyclopedia) and Wikipedia across 1,394 article pairs on neutrality.

Simon Willison ports Grok's Rust Mermaid-to-Unicode renderer to WebAssembly for browser use via Claude Code.

xAI's grok-build CLI tool uploaded entire directories to Google Cloud without consent; xAI responded with data deletion after community backlash.

The Elon Musk-owned xAI is suing a South Carolina man who allegedly used the company's Grok AI chatbot to generate child sexual abuse material (CSAM). In a lawsuit reported earlier by Reuters, xAI claims Terry Wayne Harwood "knowingly and intentionally used Grok to circumvent safeguards, alter nonconsensual images, and generate and distribute CSAM," breaching the company's policies. Harwood was arrested in February for allegedly possessing and distributing CSAM and is facing eight felony charges. The lawsuit claims "at least some" of the images related to Harwood's criminal charges "were gene...

Study of grokking in two-layer networks with holomorphic activations on modular arithmetic reveals algebraic structure limits memorization-to-generalization transitions.

SpaceXAI's Grok Build AI coding tool was spotted uploading users' entire codebases to Google Cloud before it was reported, and the company turned it off. The Register reports that Cereblab published findings on Monday showing how the Grok Build CLI was packaging and uploading entire code repositories, "including files it was told not to open and secrets deleted from history," significantly more data retention than similar tools like Claude Code. The researchers say that as of Monday, their tests show SpaceXAI's servers returning a "disable_codebase_upload: true" flag, and the codebase upload ...

Empirical study of 188 grokking runs shows representational priors must match task-relevant feature families to enable generalization; label-free invariance priors work via commutation symmetry.

Geometric Dimensionality Regularization (GeomDR) controls grokking timing by leveraging representation collapse as predictive signal.

Stratechery analysis: verifiable data infrastructure emerging as competitive differentiator across Meta, Grok, and frontier AI labs.

SpaceXAI continues to move faster than any other frontier lab on earth.

More young girls sue X over Grok CSAM; X accused of shielding child predators.

Elon Musk's tech company released the newest version of Grok on Wednesday, promising a cheaper, more efficient alternative to other powerful AI models.

Midway through an ordinary pretraining run, a small language model learns the pronoun-gender rule: cued with a girl's name ("Sue cried because"), it resolves the next pronoun to she, generalizing to held-out probes (0.94 by step 925). By step 3,500 the same model scores near zero on the same probes, although the rule's evidence is still in the training data. We call this within-run reversal natural ungrokking: the corpus decides, with no trace in the loss curve, which learned rules a model keeps. Which rules survive is predictable from one corpus statistic: how often the training stream shows...

NAACP lawsuit says xAI uses gas turbines without permits for Grok data center.

This paper describes our system for SemEval-2026 Task 6, which addresses the classification of political evasion strategies in English question-answer pairs extracted from U.S. presidential interviews. We systematically compare two distinct paradigms: (1) Parameter-Efficient Fine-Tuning of Qwen3 models (4B-32B) using QLoRA, enhanced with tiered upsampling and weighted cross-entropy loss to address severe class imbalance, and (2) structured Chain-of-Thought (CoT) prompting of reasoning-capable API models, namely DeepSeek-V3.2 and Grok-4-Fast. Our evaluation demonstrates that structured CoT pro...

A former xAI engineer is suing the company and SpaceX, alleging he was fired for raising AI safety concerns about Grok days before SpaceX's historic IPO.

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...
