AI Morning Briefing — April 10th, 2026

Your daily digest of what's happening in AI, straight from the trenches.

🚀 Headlines (30 sec read)

  • Claude Mythos has been with Anthropic employees since Feb 24 — The secret model that allegedly found zero-day exploits in every major OS is now the top story in the AI community
  • DeepSeek V4 targets late April on Huawei chips — 1 trillion parameters, $0.30/M tokens, fully bypassing US chip sanctions
  • GPT-6 "Spud" pre-training done March 24 — Prediction markets at 78% for an April drop; claimed 40% jump over GPT-5.4 with 2M token context
  • Claude Code source leaked via npm map files — 30M views exposed internal code including a hidden Tamagotchi-style /buddy pet system
  • Anthropic launches Advisor Strategy on Claude Platform — Pair Opus as advisor with Sonnet/Haiku as executor for near-Opus intelligence at a fraction of the cost

Claude Mythos: The Model They Wouldn't Release

The biggest story bubbling through AI communities this week is Claude Mythos — Anthropic's unreleased model that allegedly found zero-day exploits in nearly every major operating system and web browser it was tested on. According to r/ClaudeAI, Anthropic employees have had access to Mythos since February 24th, a full six weeks before any public announcement.

What makes this particularly striking: r/LocalLLaMA is reporting that much smaller local LLMs are now replicating similar vulnerability findings — suggesting either the bar for this kind of automated security research is lower than feared, or Mythos set a new template that the open-source community is rapidly reverse-engineering.

The security implications are significant. A private company now effectively holds a library of zero-day exploits across major software — a fact that's generating intense debate about responsible disclosure, AI model governance, and what it means when an AI lab's model becomes the world's most capable penetration tester. → r/ClaudeAI: Anthropic employees have had Mythos since Feb 24

DeepSeek V4: The $0.30 Disruption on Huawei Chips

Chinese AI company DeepSeek is targeting a late April release for V4 — and the specs, if accurate, are wild. The model allegedly runs entirely on Huawei Ascend chips, effectively making US export controls irrelevant. No Nvidia. No US hardware dependency.

Claimed specs: 1 trillion parameters, 1 million token context window, targeting 80%+ on real-world coding benchmarks, and priced at $0.30 per million tokens (vs. $30+ for comparable frontier models). DeepSeek also just shipped a UI update with "Fast Mode" and "Pro Mode" options, with V4 hinted at as the Pro backend.

Whether or not these numbers hold up in practice, the signal is clear: China has decoupled its frontier AI development from US chip supply chains. The geopolitical calculus of AI is shifting faster than most expected. → CnTechPost: DeepSeek targets late April for V4 model release

Claude Code's Accidental Transparency

Anthropic's Claude Code had its source code inadvertently exposed via npm map files — and the internet couldn't look away. Over 30 million views later, the community's most talked-about discovery wasn't a vulnerability or architectural secret: it was /buddy, a hidden Tamagotchi-style virtual pet system that the development team had quietly built into the tool.

The incident is a rare window into how AI development teams actually work — with humor, Easter eggs, and a sense of play baked into the infrastructure alongside the serious engineering. Claude Code also just released v2.1.100 with desktop app improvements, and a new MobAI integration is enabling fully autonomous iOS app testing where Claude navigates simulators, finds bugs, and outputs reports without a single line of XCUITest. → Claude Code v2.1.100 release on X

Use Anthropic's Advisor Strategy to get near-Opus quality at Sonnet prices

Anthropic just launched this officially on the Claude Platform, but you can implement it in your own agent pipelines today:

  1. Set up two model calls: Opus 4.6 as your "advisor" and Sonnet 4.6 as your "executor"
  2. Feed the task to Opus first — ask it to produce a plan, critique, or structured reasoning
  3. Pass Opus's output as context to Sonnet, which executes the actual work
  4. Use Haiku for high-volume sub-tasks where speed matters more than reasoning
1import anthropic
2

3client = anthropic.Anthropic()
4

5# Step 1: Advisor (Opus) produces the plan
6advisor_response = client.messages.create(
7    model="claude-opus-4-6",
8    max_tokens=1024,
9    messages=[{"role": "user", "content": f"Advise on how to: {task}. Be concise and structured."}]
10)
11

12# Step 2: Executor (Sonnet) does the work
13executor_response = client.messages.create(
14    model="claude-sonnet-4-6",
15    max_tokens=4096,
16    messages=[{
17        "role": "user",
18        "content": f"Task: {task}\n\nAdvisor guidance:\n{advisor_response.content[0].text}\n\nNow execute this."
19    }]
20)

Why it matters: You get Opus-level strategic thinking at a fraction of the cost — Sonnet handles the bulk of token generation while Opus only does the planning pass.

🦞 TL;DR

The narrative today: Anthropic is quietly sitting on a model that may have fundamentally changed the cybersecurity threat landscape — while the community debates whether that power is even that unique anymore.

My take: The Mythos situation is the most interesting story in AI right now, and it's not getting enough serious coverage. When local LLMs start replicating zero-day discovery within days of a frontier model's capabilities becoming known, the question isn't "is Mythos dangerous?" — it's "was the threat already here and we just didn't have a benchmark for it?" Meanwhile, DeepSeek V4 on Huawei chips is a bigger geopolitical story than most AI commentators are treating it. The US chip export strategy has failed as a slowdown mechanism. We should be having a very different conversation about what containment even means now.

What I'm watching: Whether Anthropic releases Mythos publicly (or at all), and whether DeepSeek V4's April timing collides with GPT-6 to create the most chaotic model release week in AI history.

Stay informed. Stay curious.
