Elon Musk's SpaceXAI is launching Grok 4.5, its smartest model yet, and its first release since going public and acquiring the AI coding startup Cursor.
Why it matters: The new model is being pitched as a coding and agentic-work tool, more than a consumer-facing chatbot — one that Musk says is "maximally truth-seeking" compared to its competitors.
OpenAI is rolling out a new generation of voice models for ChatGPT, aiming to make conversations with its AI sound more natural while routing these queries to its best models.
Why it matters: The company sees this as a step toward a future where voice is the primary way people interact with AI.
My 1,900-mile road trip last week in an electric vehicle proved it's easily doable, but the charging experience is still not as seamless and convenient as pumping gas.
Why it matters: Driving an EV is delightful. Charging an EV is what gives people anxiety. Until that problem is solved, EV sales in the U.S. will remain lackluster.
The AI boom is creating a new class of shock-resistant economies.
Why it matters: Countries making the chips, servers and infrastructure behind AI are ducking the worst of the energy crises, tariffs and geopolitical turmoil.
For decades, economists looked at income, geography and natural resources to explain which countries pulled ahead.
Arya Bolurfrushan is founder of an AI startup that's raised over $60 million from brand-name investors.
He's also a crook.
Driving the news: Federal prosecutors this week unsealed documents showing that Bolurfrushan secretly pleaded guilty in June 2025 to participating in a large insider trading scheme tied to mergers and acquisitions.
Public access to OpenAI's GPT-5.6 model is coming on Thursday, and early reviewers are already praising its speed, creativity, math skills and ability to complete complex tasks.
The big picture: GPT-5.6's public rollout will intensify competition among the leading AI developers, just days after Anthropic (re-)launched the widely praised Fable 5.
The Trump administration has given OpenAI the green light for a broad launch of its advanced GPT-5.6 model, a source familiar with the situation confirmed to Axios Tuesday.
OpenAI announced late Tuesday night that GPT-5.6 flagship model Sol, as well as lower tiers Terra and Luna, will launch publicly this Thursday.
Why it matters: The government and the world's most advanced AI companies are negotiating how people get access to powerful technologies case-by-case, in real time.
The OpenAI Deployment Company agreed to acquire Northslope, an applied AI firm, OpenAI shared exclusively with Axios, marking its second acquisition focused on enterprise AI use since launch.
The big picture: AI companies are starting to do work that was traditionally left to consulting firms, betting that helping customers implement AI will be as important as building the models themselves.
Wall Street's sell-side analysts published a slew of bullish reports on SpaceX Tuesday, while cautioning that years of massive investments will be needed to bring Elon Musk's vision for the company to fruition.
Why it matters: These notes are some of the clearest and most well-informed public statements yet on the financial prospects for SpaceX.
South Korea's other massive memory chipmaker, SK Hynix, plans to sell $28 billion in stock in the U.S. later this week, even as waves of volatility batter the chip shares.
Why it matters: The offering will be a major test of whether investors are still gaga for memory chip stocks.
SK Hynix's offering comes just a month after the market absorbed the enormous SpaceX IPO.
A dozen or so people gathered around a table in suburban Washington and were presented with a tense scenario: Someone had detonated a space nuke, American satellites were failing, and fighting in Europe and Asia was intensifying.
How could this happen, they wondered. To whom could the attack be attributed? How quickly could the U.S. repopulate its constellations?
Are world powers in contact? How could they avoid an exchange of intercontinental ballistic missiles? And how were the people back home, not bombed out but very much confused, stomaching crippled GPS and financial markets?
The big picture: While the mental gymnastics were very much real, the world-ending stakes were not. The deliberations were part of a tabletop exercise put on by Fuse, a fusion-energy company.
China this week test-fireda submarine-launched ballistic missile, a rare move.
Why it matters: The test delivered a dummy warhead deep into the Pacific Ocean, according to state media, allowing Beijing to flex its muscles and gauge international reaction.
Criticism quickly poured in from Australia, Japan and the U.S.
Some countries were reportedly warned of the launch ahead of time.
Apple said Wednesday it expects to spend over $30 billion in its expanded partnership with Broadcom that will lead to more than 15 billion chips being made in the U.S.
Why it matters: It's the largest element to date in an Apple program designed to have more components made in the U.S., even as nearly all of its devices are made elsewhere.
