Today, we've got Anthropic launching a cybersecurity AI model so powerful they won't release it publicly, Meta debuting its comeback model Muse Spark, OpenAI pitching robot taxes and a four-day workweek, and the AI coding wars reaching a fever pitch.
On this day in 2026…
Meta was preparing for the launch of Llama 4, its ambitious Mixture-of-Experts architecture that would go on to receive mixed reviews and eventually spark a major overhaul of the company's entire AI strategy — leading to the very Muse Spark announcement we're covering this week. Quite the full-circle moment.
🛡️ Anthropic Launches Project Glasswing with Claude Mythos
Anthropic has introduced Claude Mythos Preview, a powerful AI model designed to identify software vulnerabilities. Rather than releasing it publicly, the company is rolling it out in a controlled way through a cybersecurity initiative called Project Glasswing, involving more than 40 partners, including major tech firms like Apple, Google, and Microsoft. According to Anthropic, the model has already identified thousands of previously unknown vulnerabilities — including decades-old bugs — though these claims have not been independently verified. Experts say the model’s real significance may be less about enabling cyberattacks and more about exposing how fragile modern software security already is.
🔥 Meta Debuts Proprietary Muse Spark Model
Meta launched Muse Spark, its first major AI model from the new Superintelligence Labs led by Chief AI Officer Alexandr Wang. The proprietary model powers the Meta AI app and website, with plans to roll it out across WhatsApp, Instagram, and Facebook. The move signals a shift away from Meta’s open-weight Llama strategy, and the Meta AI app quickly surged to around No. 5 on the U.S. App Store following the launch.
💼 OpenAI Pitches Robot Taxes and a Four-Day Workweek
OpenAI just dropped a sweeping policy blueprint for the AI economy — including a Public Wealth Fund that would give every American a stake in AI-driven growth, proposals to tax automated labor as the tax base shifts away from human workers, and incentives for companies to pilot 32-hour workweeks with no loss in pay. It’s one of the company’s most ambitious policy pushes yet, landing at a moment of rising anxiety over job loss, inequality, and who actually benefits from the AI boom.
⚔️ OpenAI Slams Anthropic in Investor Memo
In a memo to investors, OpenAI took direct aim at Anthropic, criticizing its “conservative” approach to scaling compute and positioning itself as having a growing “compounding advantage” in infrastructure and cost. With both companies collectively valued at over $1 trillion and reportedly preparing for potential IPOs, the rivalry between the two AI leaders is rapidly intensifying.

💻 The AI Code Wars Are Heating Up
The Verge’s David Pierce explains how OpenAI, Google, and Anthropic are competing for dominance in AI-powered coding tools, which has become a key battleground in the AI industry. The article traces how coding was one of the earliest strong use cases for large language models—starting with tools like GitHub Copilot—and shows how these systems are evolving from simple code autocomplete into more capable AI assistants and emerging agent-style workflows.
🏦 Trump Officials Pushing Banks Toward Mythos
In a surprising twist, government officials are reportedly encouraging major banks to test Anthropic’s Mythos model — a notable shift given that the Department of Defense recently flagged Anthropic as a supply-chain risk. The situation highlights the growing complexity and contradictions shaping AI adoption policy.
😎 Bluesky Users Blame Everything on Vibe Coding
Every bug, every glitch, every weird UI choice — it must be vibe coding. Ars Technica documents how Bluesky users have turned "vibe coding" into the ultimate tech boogeyman, even as professional developers are embracing AI coding tools faster than ever.
🤖 Eclipse Raises $1.3B for Physical AI
VC firm Eclipse has raised a $1.3 billion fund to invest in “physical AI” startups — including robotics, autonomous systems, energy, infrastructure, and defense technologies.

👓 Snap's AI Glasses Are Getting Closer
Snap is moving closer to releasing its next-generation AI-powered Spectacles after years of primarily developer-focused versions. The company is ramping up development with a new Qualcomm partnership as it prepares for a potential broader release later this year, signaling renewed momentum in the smart glasses space.
🔐 Anthropic Temporarily Bans OpenClaw Creator
Anthropic temporarily suspended and then reinstated the creator of OpenClaw around the same time it changed pricing rules for third-party “harnesses” like OpenClaw, sparking debate in the developer community and highlighting ongoing tensions between AI platforms and tools built on top of them.
📰 At HumanX Conference, Everyone Was Talking About Claude
Anthropic was the undisputed star of San Francisco's HumanX conference this week. From enterprise customers to developers, Claude dominated the conversation — a sign of just how much momentum Anthropic has built in the enterprise AI market.
That's it for this week. From Anthropic's Mythos shaking up cybersecurity to Meta's big comeback with Muse Spark — it's clear the AI race isn't slowing down anytime soon. If you found something useful in here, send it to someone who'd appreciate it. 🎉
