Senator Bernie Sanders just proposed the American A.I. Sovereign Wealth Fund Act, which would slap a one-time 50% equity tax on giants like OpenAI, Anthropic, and xAI. The plan hands the federal fund voting shares and board seats to distribute tech wealth back to the public. Sanders argues AI was built on collective human knowledge, so tech billionaires shouldn't keep all the spoils.
xAI just launched Grok Build in beta for SuperGrok and X Premium+ subscribers.

Why it matters: subscribers can now tap Grok's models locally without paying extra API fees.
xAI just released an early beta of Grok Build, a dedicated agentic command-line interface built to code, build applications, and automate developer workflows. It is currently locked behind the top-tier SuperGrok Heavy subscription, with xAI planning to fine-tune both the underlying model and the tool based on early user feedback.
xAI just rolled out Grok Voice mode for Apple CarPlay, letting drivers chat with the AI hands-free right from their dashboard. Enabled by iOS 26.4, the integration follows Apple's strict distraction guidelines by keeping replies audio-only without on-screen text. After living mostly inside Teslas, Grok is now joining ChatGPT and Perplexity across millions of everyday cars.
Google DeepMind, Microsoft, and xAI just agreed to let the U.S. Commerce Department review new AI models before public release. The Center for AI Standards and Innovation will conduct pre-deployment evaluations, expanding on 40 reviews already completed with OpenAI and Anthropic. Frontier AI oversight is rapidly becoming a standard gate before launch.
xAI just rolled out Grok 4.3 alongside a new web-based voice cloning suite. The flagship model features permanently active reasoning, a 1-million-token context window, and agentic tool use like web browsing and code execution. API pricing has dropped roughly 40% to 60% compared to Grok 4.2, costing $1.25 per million input tokens and $2.50 per million output tokens.
X just announced a complete, ground-up rebuild of its advertising platform, rolling out a new AI-driven Ads Manager. Powered by retrieval and ranking tech from xAI, the new stack aims to deliver real-time, context-aware ad targeting based on live platform activity.

A federal jury just rejected Elon Musk’s high-stakes lawsuit against Sam Altman and OpenAI after only two hours of deliberation, tossing the claims because the statute of limitations had run out. Musk cofounded OpenAI and sued in 2024, claiming the startup abandoned its founding nonprofit mission in favor of profits. Why it matters: After weeks of chaotic Silicon Valley drama on the stand, the trial ended in a total loss for Musk, leaving Altman’s grip on OpenAI fully intact.
xAI just rolled out Grok Voice 1.0 via API, designed for complex multi-step enterprise workflows like customer support and phone sales. It reasons in the background with zero added latency, handles noisy calls and strong accents across 25+ languages, and is already handling Starlink's support lines.
X just launched custom timelines powered by Grok, allowing users to pin 75+ niche topics directly to their home tabs. The feature pairs Grok's post-level semantic understanding with personalized recommendation algorithms to curate hyper-tailored feeds. Early access is currently rolling out to Premium subscribers on iOS, with Android coming soon.
SpaceX just confirmed an unusual deal with AI coding platform Cursor, securing the option to acquire the startup later this year for $60 billion or pay a $10 billion fee for their joint work. The partnership pairs Cursor's software with SpaceX's massive Colossus supercomputer to build coding and knowledge work models as competition heats up against Anthropic and OpenAI.
xAI just rolled out Grok 4.3 Beta to its $300/month SuperGrok Heavy subscribers, adding direct generation of formatted PowerPoint decks, populated spreadsheets with working formulas, and PDFs. Musk clarified the model sits at roughly 0.5 trillion parameters, with a 1T version close to finishing training. Why it matters: Grok is finally expanding from chat and reasoning into hands-on office productivity deliverables.
X just launched a new photo editor directly inside its post composer on iOS, packing long-awaited drawing and text tools alongside two platform exclusives. Users can modify photos via written prompts with Grok-powered "Edit with words" and apply a redaction blur to mask sensitive info before posting. It is live now on iOS, with Android rolling out soon.
OpenAI just urged attorneys general in California and Delaware to investigate Elon Musk for alleged anti-competitive behavior ahead of their April 27 trial. The company claims Musk even coordinated attacks with Meta CEO Mark Zuckerberg to hobble OpenAI and boost xAI. Why it matters: With jury selection weeks away, the bitter feud over AGI governance is escalating into a public antitrust battle.
SpaceX just filed confidentially with the SEC for an IPO that could value the company at $1.75 trillion and raise $75 billion. After absorbing xAI in February, ballooning compute and Starship costs have turned Elon Musk's empire toward public markets.
Elon Musk just unveiled Terafab, a new Texas chip manufacturing plant operated by Tesla, SpaceX, and xAI that targets 50x current global compute output. The vertical facility plans to fabricate chips for cars, Optimus robots, and solar-powered orbital satellites. Why it matters: Building a cutting-edge fab from scratch is an enormous gamble, but orbital AI compute might be Musk's boldest bet yet.
Elon Musk just confirmed that xAI is preparing to roll out "Grok Computer," an AI agent built to take over screen, mouse, and keyboard inputs. The leak surfaced after users spotted a hidden toggle in Grok's web code, hinting at a trial run for the rumored Macrohard project. It is currently undergoing testing.
Elon Musk just revealed that xAI "was not built right" and is undergoing a ground-up rebuild after 9 of its 11 original co-founders departed, including Grok Code lead Guodong Zhang. Musk admitted Grok is lagging in coding, prompting raids on Cursor talent as the startup reshuffles ahead of a massive planned IPO.
