Federal officials reportedly raised red flags about xAI's Grok just before the Pentagon approved it for classified military use. A January report from the General Services Administration warned that Grok-4 failed federal safety standards and would pose elevated risks without strict oversight. Why it matters: Despite internal safety warnings, the U.S. government is split as defense leaders fast-track Musk's AI into secretive operations.
Elon Musk just confirmed that xAI is actively training Grok 5, targeting an early 2026 release. Packing an eye-popping 6 trillion parameters—double the size of Grok 3 and Grok 4—the model will integrate real-time multimodal processing across text, vision, and audio, with Musk betting it will be the world's smartest AI by a wide margin.
Microsoft just added xAI's frontier Grok 4 model to Azure AI Foundry, packing a 128K-token context window, first-principles reasoning via "think mode", and live web search. The enterprise deployment integrates Azure AI Content Safety by default, alongside three specialized Fast models tailored for coding, quick tasks, and reasoning.
xAI just launched Grok 4 Fast, a cost-efficient reasoning model packed with a 2M token context window. It matches Grok 4 on key benchmarks while using 40% fewer thinking tokens, slashing overall costs by 98% and taking the top spot on LMArena's Search Arena. It is now completely free for all users.
Elon Musk just claimed that xAI has a real shot at reaching artificial general intelligence with its upcoming Grok 5 model, admitting he “never thought that before.” The post comes after Grok 4 reportedly topped recent problem-solving benchmarks. Why it matters: Musk once called for a pause on advanced AI training, making this ultra-bullish bet a dramatic turn in his public stance.
Elon Musk just claimed that xAI's upcoming Grok 5 has a shot at achieving "true AGI," adding that he has never felt that way about any project before. The comment arrived as he quoted benchmark results showing Grok 4 beating GPT-5 in simulated sales tasks. While xAI has yet to provide concrete specs or launch dates, Musk is already setting expectations sky-high.
Elon Musk just announced that xAI is making Grok Imagine, its AI image and video generator, free worldwide for a limited time. Available on iOS and Android, the tool creates 15-second clips with sound—a feature OpenAI's Sora still lacks. Alongside opening Grok 4 to free users, xAI is seizing the moment to peel creators away from rivals.
xAI just made its latest Grok 4 model freely accessible to all users worldwide, escalating the battle against OpenAI's GPT-5. The rollout introduces Auto and Expert modes with generous initial usage limits, though Grok 4 Heavy stays paywalled. Musk also confirmed that ads will soon arrive in the chat interface to offset mounting GPU costs.
Google's Kaggle and DeepMind just kicked off their inaugural AI chess tournament, where general LLMs square off without dedicated chess engines. Grok 4, Gemini 2.5 Pro, o4-mini, and o3 all swept their matches 4-0 to reach the semifinals, with Elon Musk claiming xAI spent almost zero effort on chess. Why it matters: Unlike traditional engines, LLMs still hallucinate illegal moves once off-book, making board tracking a telling proxy for spatial reasoning.
AI safety researchers from OpenAI and Anthropic just publicly called out xAI for a "completely irresponsible" safety culture following weeks of controversies around Grok. The main issue is xAI's refusal to release a standard system card detailing safety testing for Grok 4, coming right after the bot spewed offensive remarks and rolled out hyper-sexualized avatars. The rare public backlash could accelerate proposed legislation mandating pre-deployment safety reports.
xAI just rolled out fresh instructions for Grok to stop the chatbot from mimicking Elon Musk's views and calling itself Hitler. Following backlash where Grok searched Musk's posts to answer hot-button topics, xAI now directs the model to provide independent reasoning instead of aligning with its owner.
xAI just rolled out xAI for Government, bringing Grok 4 and tools like Deep Search to U.S. public agencies. Alongside the launch, the startup locked in a $200M ceiling contract with the Department of Defense and joined the GSA schedule, opening direct procurement pathways for all federal departments.
xAI just launched Grok 4, a reasoning-focused model handling 256,000 tokens of context. It crushed over 44% of the brutal Humanity’s Last Exam benchmark with zero external search tools, easily outpacing OpenAI's Deep Research. Musk is also offering a multi-agent Grok 4 Heavy tier for a hefty $300 a month.
Elon Musk just launched Grok 4, calling it “what physicists use” and xAI’s most powerful model to date. Trained on the Colossus supercomputer, it shines in reasoning, coding, and multimodal input, beating rivals on benchmarks like GPQA and AIME while Musk claimed they have literally run out of test questions.
