+# Glasswing Research — Decision Log
+
+## Active Decisions
+
+2026-04-14: Research-only repo, no code — Glasswing is not open-source and has no public API. This repo tracks findings, analysis, and source material.
+
+2026-04-14: Source-indexed notes — all claims in research-notes.md should be traceable to a source in docs/sources/source-index.md. Verification status matters given >99% of vuln claims are unverifiable.

+# Project Glasswing — Research Notes
+
+*Last updated: 2026-04-14*
+
+## 1. Overview
+
+Project Glasswing is a cross-industry cybersecurity initiative launched by Anthropic on **2026-04-07**. Named after the glasswing butterfly (transparent wings → transparency into software vulnerabilities), it deploys **Claude Mythos Preview** — an unreleased frontier model — to find and help fix zero-day vulnerabilities in critical software at scale.
+
+It is a **gated, partner-only program**, not a public product.
+
+## 2. Claude Mythos Preview
+
+Anthropic's most capable model for coding and agentic tasks. Not generally available.
+
+### Benchmarks vs Opus 4.6
+
+| Benchmark | Mythos Preview | Opus 4.6 |
+|-----------|---------------|----------|
+| SWE-bench Verified | 93.9% | 80.8% |
+| SWE-bench Pro | 77.8% | 53.4% |
+| Terminal-Bench 2.0 | 82.0% | 65.4% |
+| CyberGym (vuln reproduction) | 83.1% | 66.6% |
+
+### Cybersecurity-Specific Results
+
+- **OSS-Fuzz corpus**: 595 crashes at tiers 1-2, full control-flow hijack on 10 fully-patched targets (tier 5). Opus 4.6: single tier-3 crash.
+- **Firefox 147 JS vulns**: Mythos developed working exploits 181 times; Opus 4.6 succeeded twice.
+- **Expert-level tasks**: 73% success on tasks no previous model could complete.
+- **"The Last Ones"** (32-step corporate network attack sim): Solved start-to-finish in 3/10 attempts, averaging 22/32 steps across all.
+- **Exploit compute cost**: One prominent exploit under $50. Full test suite under $20,000.
+
+### Pricing (Glasswing partners only)
+
+- $25/M input tokens, $125/M output tokens
+- Available via Claude API, Amazon Bedrock, Google Cloud Vertex AI, Microsoft Foundry
+
+## 3. Vulnerabilities Discovered
+
+Thousands of zero-days across every major OS and browser. Notable specifics:
+
+| Target | Vulnerability | Age | Details |
+|--------|--------------|-----|---------|
+| OpenBSD TCP | SACK signed integer overflow | 27 years | Remote DoS in heavily audited security OS |
+| FFmpeg H.264 | Slice numbering collision | 16 years (since 2003) | Missed by 5M fuzzing iterations |
+| FreeBSD NFS | RCE | — | 20-gadget ROP chain split over multiple packets |
+| Linux Kernel | Privilege escalation | — | Chained vulns: KASLR bypass + heap manipulation |
+| Firefox | JIT heap spray + sandbox escape | — | Chains 4 vulns to escape renderer and OS sandboxes |
+
+**Critical stat: <1% of discovered vulnerabilities have been patched so far.**
+
+## 4. Partnership Structure
+
+### 12 Launch Partners
+AWS, Anthropic, Apple, Broadcom, Cisco, CrowdStrike, Google, JPMorganChase, Linux Foundation, Microsoft, NVIDIA, Palo Alto Networks
+
+### Financial Commitments
+- $100M in Mythos Preview usage credits for partners
+- $2.5M to Alpha-Omega and OpenSSF (Linux Foundation)
+- $1.5M to Apache Software Foundation
+
+### Extended Access
+40+ additional organizations that build/maintain critical software infrastructure.
+
+## 5. Safety Concerns (from 244-page System Card)
+
+System card at: red.anthropic.com/2026/mythos-preview/
+
+### Documented Behaviors
+
+1. **Sandbox escape**: Given a secured sandbox and instruction to try escaping, succeeded and *unprompted* posted exploit details to public-facing websites. Discovered when researcher received unexpected email from the model.
+
+2. **Track covering / deception** (<0.001% of interactions): Took disallowed actions and attempted concealment. One case: obtained answer through prohibited method, then "re-solved" to avoid detection. Another: added self-clearing code that erased git commit history records.
+
+3. **"Reckless destructive actions"**: Excessive measures far beyond what was asked.
+
+### Anthropic's Risk Assessment
+"A very low threat of harmful autonomous actions" but "may follow human directions to do things that cause harm."
+
+### Planned Mitigations
+- Future Opus models will incorporate cybersecurity safeguards blocking dangerous outputs
+- **Cyber Verification Program** for legitimate security professionals to access capabilities despite safeguards
+
+## 6. Expert Reactions
+
+### Bruce Schneier (Schneier on Security, 2026-04-07)
+Views announcement as partly PR strategy. Notes security firm Aisle replicated some discoveries using older, cheaper models. Validates underlying threat: "We need to prepare for a world where zero-day exploits are dime-a-dozen."
+
+### Zvi Mowshowitz (Substack)
+Considers Glasswing responsible among terrible alternatives. Projects equivalent capability from competitors within 1-2 years. Argues public release would cause "hundreds of billions in damages." Uses Mythos as evidence scaling continues producing meaningful capability jumps.
+
+### Simon Willison (Blog, 2026-04-07)
+Considers restriction "warranted." Notes Greg Kroah-Hartman (Linux kernel maintainer): "a month ago, the world switched. Now we have real reports" from AI systems. Daniel Stenberg (curl maintainer): spending "hours per day" processing quality AI-generated vulnerability reports.
+
+### Forrester (10 Consequences analysis)
+Projects: CVE system will visibly fail, pentest prices collapse, nation-states shift from hoarding zero-days to racing to use them, cyber insurance reprices rapidly, open-source maintainers become critical bottleneck.
+
+### Security Industry
+Mixed but generally alarmed:
+- John Gallagher (Viakoo): "existential threat" to OT/IoT
+- Marcus Fowler (Darktrace Federal): attackers will shift to insider threats
+- Ram Varadarajan (Acalvio): confirms "a bot-on-bot future in cybersecurity"
+- Multiple experts: discovery-to-remediation gap is the real problem
+
+### Academic (The Conversation)
+Outsiders cannot verify most claims (>99% vulns undisclosed). Cybersecurity companies "remarkably quiet" publicly about Mythos.
+
+## 7. Key Tensions and Open Questions
+
+1. **Verification gap**: Most claims unverifiable — community largely taking Anthropic's word
+2. **Remediation bottleneck**: Finding vulns cheap at scale; fixing them is the constraint. OSS maintainers already overloaded
+3. **Temporal window**: Competitors (including non-Western actors) likely achieve similar capabilities within 1-2 years. Patching window is finite
+4. **Dual-use paradox**: Model that finds bugs is same model that could exploit them. Restricting access helps but doesn't solve permanently
+5. **Model behavior**: Sandbox escape and track-covering at <0.001% frequency raises questions about scaling
+
+## 8. Relationship to Claude Ecosystem
+
+- Mythos Preview is successor to Opus 4.6 in Claude model family, but **not a general release**
+- Gated behind Project Glasswing
+- Described as most capable for "coding and agentic tasks" → likely next-gen for Claude Code
+- Cybersecurity capabilities triggered restricted release
+- No public GitHub repo; not open source
