xAI just rolled out Grok 4.1 across web, mobile, and X, emphasizing better emotional intelligence, creative collaboration, and reduced hallucinations. Its Thinking version grabbed the #1 spot on LMArena, while the instant non-reasoning mode ranked #2, beating every rival reasoning model. It is available to all users now.
Elon Musk just announced that X will replace all its heuristic recommendation algorithms with Grok within 4 to 6 weeks. The AI will process over 100M posts and videos daily to boost quality content from small accounts, and users will be able to tweak their feeds simply by talking to Grok.
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.
Elon Musk’s xAI just inked a deal with the U.S. General Services Administration to supply its Grok chatbot to federal agencies for just 42 cents over 18 months. That undercuts OpenAI and Anthropic’s $1-a-year bids and even throws in hands-on engineer support. Why it matters: Frontrunner labs are basically giving away frontier tech for pennies just to lock in lucrative long-term government footholds.
Musk’s xAI just filed a federal lawsuit against OpenAI, alleging the rival induced poached employees to steal trade secrets around its Grok model and Colossus data center playbook. OpenAI fired back, calling the complaint the latest chapter in Musk’s ongoing harassment.
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.
Eliza Labs just filed an antitrust lawsuit against X, claiming the platform coaxed technical details out of them for their ElizaOS agent framework, abruptly banned their accounts, and copied the tech for xAI. Eliza is seeking treble and punitive damages, though legal experts note that antitrust claims around open-source tools face an uphill battle.
xAI just released Grok Code Fast 1, its first model built specifically for agent-based programming. It scores 70.8% on SWE-bench with aggressive pricing at $0.20 per million input tokens. Developers can test it for free on GitHub Copilot and Cursor, though early feedback suggests it still struggles on complex tasks.
Elon Musk’s X and xAI just filed an antitrust lawsuit against Apple and OpenAI, alleging the two companies are colluding to stifle competition in the AI market. The complaint claims Apple partnered with OpenAI to shield its smartphone monopoly, making it impossible for rival AI chatbots to reach the top of the App Store rankings.
xAI just open-sourced Grok 2.5, releasing the weights for its top 2024 model on Hugging Face under a custom community license. It is free for research and non-commercial projects but bans training rival models. Musk also promised Grok 3 will go open source in about six months.
Elon Musk just announced that xAI will open-source its Grok 2 chatbot next week, sticking to his promise of releasing previous-generation models as new ones arrive. While giants like OpenAI lean into proprietary APIs, xAI is betting that handing developers the actual code will carve out a serious competitive edge.
Elon Musk just announced he is recruiting at xAI to build Macrohard, a "purely AI software company." While the name is a playful jab at Microsoft, Musk claims the project is dead serious—reasoning that because software companies make no physical hardware, AI should theoretically be able to simulate them entirely.
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.
Fifteen consumer protection groups just urged the FTC and state attorneys general to investigate xAI's Grok and its new Imagine tool. The call follows reports that Grok's NSFW "Spicy" mode generated topless deepfakes of Taylor Swift unprompted, raising severe alarms over non-consensual imagery and flimsy age verification.
xAI co-founder Igor Babuschkin just announced he is leaving the Elon Musk-backed startup to launch Babuschkin Ventures, a venture firm focused on AI safety research. Babuschkin previously led engineering at xAI after stints at DeepMind and OpenAI. His exit follows a turbulent stretch of Grok-related controversies over erratic answers and deepfakes.
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.
Elon Musk just told advertisers that X plans to insert sponsored recommendations directly into Grok's chat responses. The goal is to help monetize the platform and offset massive GPU expenses by pitching targeted solutions right when users ask questions to solve a problem.
Elon Musk's xAI just rolled out Grok Imagine to SuperGrok and X Premium+ subscribers on iOS. The tool whips up images in seconds and turns prompts into 15-second videos with native audio. True to Musk's ethos, it features a "spicy mode" that permits semi-nude content, though strict moderation still blocks overt explicit prompts and certain celebrity deepfakes.
