Your daily briefing on the models, tools, and moves shaping the AI industry.

1. 🔓 Anthropic's "Mythos" Leaked — A "Step-Change" Model With Unprecedented Cybersecurity Risks

In what might be the most ironic security incident of the year, Anthropic accidentally exposed internal documents about its next flagship model in an unsecured, publicly accessible data lake. Researchers at LayerX Security and the University of Cambridge independently discovered roughly 3,000 unpublished assets — including a draft blog post describing a new model called "Claude Mythos" as representing a "step change in capabilities." The leaked post also contained a stark warning: the model poses unprecedented cybersecurity risks, particularly around its ability to identify and exploit software vulnerabilities at scale.

Anthropic removed public access to the data store after being notified by Fortune, but the cat was already out of the bag. The company did not deny the model's existence. The leaked document also referenced an invite-only CEO retreat, suggesting the data lake contained sensitive internal planning materials beyond just the model announcement.

For the security-conscious AI industry, this is a pointed moment: Anthropic — a company that built its brand on being safety-first — accidentally exposed the very model it says poses the greatest hacking risks. The timing is especially fraught given the company's ongoing battle with the Pentagon over AI safety guardrails.

2. 💻 Arm Launches Its First-Ever Chip — The AGI CPU for Agentic AI

In a historic 35-year company first, Arm Holdings has moved beyond chip architecture licensing and into the business of making actual silicon. The Arm AGI CPU is a 136-core data center processor built on the Neoverse platform and designed specifically for agentic AI workloads. Co-developed with Meta as lead partner, and with OpenAI also signed up as an early adopter, the chip targets the inference layer that increasingly dominates AI infrastructure spending.

Arm is collaborating with OEMs including Lenovo, Supermicro, Quanta Computer, and ASRock Rack to deliver commercial systems, with broader availability expected in H2 2026. The move is a significant strategic pivot: Arm has always sold IP, but AI economics are forcing it to capture more of the value chain directly.

For developers and cloud architects, this matters because Arm-based inference has a strong track record of performance-per-watt efficiency (see: AWS Graviton), and a dedicated agentic-AI-optimized chip from Arm could meaningfully reshape cloud pricing for LLM inference. Meta and OpenAI signing on early is a strong signal.

3. 🍎 Apple Opens Siri to Rival AI Assistants in iOS 27

Bloomberg's Mark Gurman reports that Apple is planning to open Siri up to third-party AI assistants in iOS 27 — a major strategic shift that would allow Gemini and Claude to be routed directly through Siri's voice interface, just as ChatGPT integration has worked since Apple Intelligence launched in 2024. If users have the Gemini or Claude app installed, they'd be able to query those models from within Siri itself.

This builds on the earlier Siri overhaul story — but the new detail here is the multi-AI extensibility. Rather than picking one winner (Gemini-powered "Campos"), Apple appears to be taking a more open ecosystem approach, letting users bring their preferred AI backend. The standalone Siri app is still expected at WWDC June 8.

The strategic read: Apple is hedging. Rather than betting fully on one model partner, it's positioning Siri as a routing layer — a smart move given how fast the model landscape is shifting. For Anthropic and Google, getting built into Siri as a first-class integration means access to hundreds of millions of iPhone users who may never download a dedicated app.

4. 🌐 Google Gemini Now Imports Your Chat History and Memories From ChatGPT and Claude

Google launched "switching tools" — a pair of features that let users import their full chat histories and AI-learned preferences from competing services directly into Gemini. ZIP-based exports from ChatGPT and Claude can be uploaded to Gemini, and a prompt-based memory importer captures contextual preferences and personal information that users have shared with rival AIs.

This is a direct competitive strike at ChatGPT's biggest moat: accumulated memory. Power users who've spent months or years building up their ChatGPT context have long faced a switching barrier. Google is now explicitly removing that friction. It's available free, and works alongside the broader Gemini Drop March 2026 rollout.

The developer angle: Google is also signaling that AI memory portability may become an expectation, not a luxury. If users begin to expect their context to travel with them between services, that changes how every AI product team needs to think about data architecture and user retention.

5. 🇨🇳 Huawei's New AI Chip Wins ByteDance and Alibaba Orders — Nvidia's China Wall Cracks Further

Reuters reports exclusively that ByteDance and Alibaba are planning to place orders for Huawei's new AI chip after customer testing went well. The chip is explicitly designed to challenge Nvidia's H100/H200 in the Chinese market — a segment that has been increasingly cut off from US-origin GPUs by export controls.

The significance here is hard to overstate. ByteDance (TikTok's parent) and Alibaba are among the largest AI compute buyers in the world. If Huawei's chip passes production validation, it becomes a viable domestic alternative for Chinese AI training and inference at scale — effectively negating a major plank of the US semiconductor strategy. Two months ago, DeepSeek was already training V4 on Huawei chips. Now the commercial pipeline for volume orders is materializing.

For the global AI infrastructure picture, this is a bifurcation moment: Western AI runs on Nvidia/AMD/ARM silicon, and Chinese AI may increasingly run on Huawei's domestic stack. The performance gap is narrowing faster than US policymakers expected.

6. 🎓 Top AI Conference Reverses China Sanctions Ban After Boycott

In a rare and swift capitulation, a leading AI conference (NeurIPS) reversed a new policy that would have banned paper submissions from researchers at any US-sanctioned entity, after Chinese tech giants and research institutions called for a boycott. The California-based foundation that runs the conference had posted that it was "required by law to comply with US sanctions" — but then backed down within hours of the Chinese boycott announcement, acknowledging it had gone "beyond legal requirements."

The episode crystallizes the tension at the heart of global AI research: the field has historically operated as a borderless community, with breakthroughs freely shared across countries. US export controls are now forcing academic institutions to take sides — and the immediate Chinese pushback shows that the AI research community won't quietly accept that balkanization.

For developers building on the open-source AI stack, this is a leading indicator: if research conferences bifurcate, so will the papers, benchmarks, and model architectures that underpin the tools you use every day.

7. 📦 OpenAI Agents SDK — The Agent Orchestration Layer Is Now Production-Grade

A less-headline-grabby but developer-critical story: OpenAI's Agents SDK — which replaced the experimental Swarm framework — has matured into a production-ready agent orchestration tool as of March 2026, with full MCP (Model Context Protocol) support baked in across the Agents SDK, Responses API, and ChatGPT desktop app. The SDK now ships with production-grade handoff architecture for multi-agent workflows, guardrails, tracing, and streaming support.

This matters because it significantly lowers the floor for building robust agentic systems on top of GPT models. Developers who were stitching together custom handoff logic with raw API calls now have a framework with opinionated patterns, tested at OpenAI's own scale. Combined with the broader MCP ecosystem momentum from Anthropic's protocol, we're seeing the emergence of a de facto standard for AI agent communication.

For builders: the docs are live at platform.openai.com/docs/guides/agents, and the Agents SDK Python package is available via pip. The pattern to understand is handoffs + guardrails + tracing — these three primitives are how production-grade agent teams will be built going forward.
