San Francisco | April 8, 2026

Anthropic built a model that cracks software for under $50 a run. Mythos Preview found zero-day vulnerabilities in every major OS and browser, including a TCP flaw hidden inside OpenBSD for 27 years. Project Glasswing gives 12 partners and 40 organizations early access to scan their code before similar capabilities reach other labs.

Z.ai's GLM-5.1 briefly topped the SWE-Bench Pro coding benchmark before Mythos crushed it the same afternoon. The real story: eight hours of autonomous coding, shipped open source under MIT, trained on zero American chips.

Most AI teams still cannot tell you where the token bill goes. Gartner puts observability adoption at 15 percent. The tools exist. The sequencing is wrong.

Anthropic Launches $100M Glasswing Coalition as Mythos Finds Decades-Old Zero-Days

Anthropic's unreleased Mythos Preview model found and exploited zero-day vulnerabilities across every major operating system and browser in red team testing. A 27-year-old TCP bug in OpenBSD. A 16-year-old FFmpeg flaw missed by five million automated scans. Working Firefox exploits 181 times where the current flagship managed twice.

Project Glasswing puts $100 million in credits on the table for 12 launch partners including Amazon, Apple, Google, Microsoft, and CrowdStrike, plus 40 additional organizations. The goal: defensive scanning before similar capabilities reach other labs within 6 to 18 months. Each successful exploit run cost under $50. After the preview period, pricing sits at $25 per million input tokens and $125 per million output.

The same company that left a draft blog post in a publicly searchable data store last month now positions itself as the cybersecurity industry's gatekeeper. The capability is real. The trust question remains open.

Why This Matters:

Reality Check

What's confirmed: Mythos found zero-days in every major OS and browser tested. 181 Firefox exploits versus 2 for Opus 4.6. Coalition includes Amazon, Apple, Google, Microsoft, CrowdStrike, and seven others.

What's implied (not proven): That Anthropic can responsibly gatekeep access while facing a Pentagon supply-chain risk label and two security lapses in two weeks.

What could go wrong: Defensive tools get flipped by adversaries. Hexstrike-AI collapsed zero-day timelines from weeks to minutes after release earlier this year.

What to watch next: Whether the 90-day coordinated disclosure window keeps pace with the 6-to-18-month capability proliferation timeline.

Anthropic's Mythos Killed Friction-Based Security. Now What?
Anthropic's Mythos found bugs that survived 27 years. Project Glasswing gives defenders months, not years, before similar capabilities spread. The old security playbook is dead.

The One Number

181 — Working Firefox exploits developed by Anthropic's unreleased Mythos Preview model in cybersecurity testing, compared to 2 by Opus 4.6 across several hundred attempts. The model also found 10 full control-flow hijack vulnerabilities in open-source software where previous models found one each, including a 27-year-old OpenBSD TCP flaw. Over 99% of the thousands of vulnerabilities Mythos discovered remain unpatched. Anthropic published the results before releasing the model.

85% of GenAI Deployments Fly Blind on Token Costs, Gartner Estimates

A customer support bot running 10,000 conversations daily burns 400 million tokens before lunch. Gartner estimates only 15 percent of GenAI deployments have any cost observability. The rest discover the bill at the end of the quarter.

The tools exist but the sequencing trips teams up. Most grab budget caps before they know where the money goes. Langfuse and Helicone handle visibility. Portkey and LiteLLM enforce limits. ccusage, with 12,500 GitHub stars in weeks, gives Claude Code subscribers the usage dashboard Anthropic refuses to provide. Observe first, cap second.

Z.ai's GLM-5.1 Tops SWE-Bench Pro, Then Runs Eight Hours Without Human Help

Z.ai's GLM-5.1 briefly claimed the top spot on SWE-Bench Pro at 58.4, edging past GPT-5.4 and Claude Opus 4.6. Hours later, Anthropic's Mythos Preview posted 77.8 on the same test. The crown lasted half a day.

The benchmark moment matters less than what followed. GLM-5.1 ran 655 iterations and 6,000 tool calls optimizing a vector database over eight continuous hours, restructuring its approach six times without human guidance. Trained on Huawei Ascend chips under US sanctions, shipped open source under MIT, priced at one-fifth of Claude Opus 4.6.

Why This Matters:

GLM-5.1 Beats GPT-5.4 on SWE-Bench, Works 8 Hours Alone
6,000 — Tool calls GLM-5.1 made optimizing a single database, six times beyond what any model achieved in a standard session

What To Watch Next (24-72 hours)


🛠️ 5-Minute Skill: Turn a Week of Activity Into a Progress Report

It is Friday at 4 PM. Your manager wants a weekly update. You did a lot this week but cannot remember what, because it is scattered across tasks, emails, and calendar entries.

Your raw input:

Calendar: 14 meetings including a client demo and two interviews.
Tasks completed: shipped auth fix, reviewed 3 PRs, finalized Q2
roadmap. Sent 38 emails. Missed deadline on vendor evaluation.

The prompt:

From this week's activity, produce: (1) top three accomplishments
with impact, (2) one thing that slipped and why, (3) top priority
for next week. Under 80 words. No filler.

What you get back:

Done:
1. Shipped auth fix, unblocks mobile release next Tuesday.
2. Finalized Q2 roadmap, shared with leadership for sign-off.
3. Client demo went well, follow-up proposal sent same day.

Slipped: Vendor evaluation, blocked by missing pricing data from two of three vendors. Following up Monday.

Next week: Close vendor evaluation and prep board deck for Thursday.

Why this works

Weekly updates fail when you list tasks instead of outcomes. The prompt forces you to connect each item to its downstream impact, which is what managers actually read for.

What to use

Claude: Better at identifying which accomplishments carry the most weight.
ChatGPT: Faster at pulling clean structure from messy inputs.

🚀 AI Profiles: The Companies Defining Tomorrow

Aria Networks wants to replace the dumb pipes inside AI data centers with infrastructure that actively optimizes how models run.

Founders

Mansour Karam serves as CEO. He previously built Apstra, a network automation company that Juniper acquired for roughly $190 million in 2021. After spending time inside Juniper working across the full hardware and software stack, he left to start Aria in 2025. Co-founder and CTO Subhachandra Chandra came from Arista, one of the dominant players in data center switching. The company is headquartered in Palo Alto and went from incorporation to live customer deployments in under 15 months.

Product

Aria sells Ethernet switches rated at 800G and 1.6T speeds, powered by a hardened version of the open-source SONiC operating system. The core differentiator is what the company calls Deep Networking: a telemetry engine that collects performance data at up to 10,000 times the resolution of conventional monitoring tools, paired with AI agents that handle load balancing and congestion management in real time. The system works across chips from Nvidia, Google, and AMD, so operators can swap hardware without rebuilding the network.

Competition

Arista dominates AI cluster networking with a $120 billion market cap. Cisco looms at $250 billion. Juniper (now part of HPE) and a growing field of whitebox vendors also compete for neocloud contracts. Aria bets that purpose-built AI networking, rather than retrofitted enterprise gear, gives it an opening.

Financing 💰

$125 million Series A from Sutter Hill Ventures, Atreides Management, Valor Equity Partners, and Eclipse Ventures. Atreides managing partner Gavin Baker joined the board.

Future ⭐⭐⭐⭐

Strong founding team with a prior exit, real customer orders on day one, and a chip-agnostic approach in a market projected to hit $30 billion by 2035. Executing against Arista at scale is the test.


🔥 Yeah, But...

Anthropic published a red team report showing its unreleased Mythos Preview model discovered 181 working Firefox exploits in testing, compared to two by its current flagship. Over 99% of the thousands of vulnerabilities the model found remain unpatched. Anthropic released the report before shipping the model. (Anthropic Red Team Report, April 2026)

Our take: Anthropic built a model so good at breaking software that it casually unearthed a TCP flaw OpenBSD missed for 27 years. Then it wrote a paper about it. The move is genuinely responsible, publishing before release so defenders get a head start. But read the fine print: over 99% of the vulnerabilities remain unpatched. The head start is more of a gentle wave from across the parking lot while someone else sprints. Anthropic gets credit for transparency. The rest of us get to wonder how many other labs found the same bugs and said nothing.
