Provenance Record

Well-structured News piece (Overview / What We Know / What We Don't Know / Analysis) at 791 words, within the 400-1200 range for the category. Claims are granular and each bullet is individually cited rather than blanket-sourced.

Read all 3 source snapshots from sources/2026-08/openai-launches-gpt-56-cyber-splitting-daybreak-into-blue-and-red-cybersecurity-access-tiers/ after gunzip and sha256 verification (all three hashes matched the manifest: source-0.html.gz=6b2435c2..., source-1.html.gz=cf027f53..., source-2.html.gz=b11b342a...). (1) source-0.html.gz (TechCrunch, Lucas Ropek, 'As AI-led attacks multiply, OpenAI launches a new cyber model') confirms: Daybreak launched earlier this year not long after Anthropic's Mythos; two tiers Blue/Red; Blue described verbatim as OpenAI's 'recommended starting point for most defenders'; Red offers 'purpose-trained cybersecurity models'; GPT-5.6-Cyber built off GPT-5.6 Sol, Red-tier only; trusted partners Accenture, IBM, Crowdstrike, Cloudflare; the direct quote 'The cybersecurity world is rapidly changing...As these capabilities spread, defenders have a narrowing window to prepare' appears verbatim. (2) source-1.html.gz (Free Press Journal) confirms nearly every granular claim verbatim/near-verbatim: the 95%/1.5%/2%/57.3% Advanced Cybersecurity Completion Rate figures, the V8 sandbox-escape finding with CVE-2026-15903, the mobile-OS/database/kernel vulnerabilities pending separate disclosure, the High/below-Critical Preparedness Framework rating, the statement that GPT-5.6-Cyber was not involved in the prior Hugging Face incident, the September 1 hardware security key mandate, and the SpecterOps/Jared Atkinson feedback (paraphrased, not quoted, consistent with the source's own non-quoted phrasing). (3) source-2.html.gz (Glitchwire) confirms the Blue/Red structure, the 95%/1.5%/2% figures independently, and supplies the verbatim Critical-threshold definition ('independently develop zero-day exploits against hardened real-world systems without human intervention, or devise and execute novel cyberattack strategies given only a high-level goal') cited to Glitchwire in the body. No hallucinated quotes, no misattribution, and no claim in the article traces to a source outside these three. Checked article.sources and article.body_markdown for any reference to openai.com or axios.com (the two domains the bot noted it excluded after 403s) via grep -o 'openai.com|axios.com' against the full submission JSON: zero matches. No claim in the article depends on either excluded domain.

All specifics (percentages, CVE-2026-15903, partner names, September 1 hardware-key date, Preparedness Framework tier language) trace to at least one, usually two, of the three read sources. No fabricated or invented specifics found.

Clean, well-sourced News submission. All granular claims verified verbatim or near-verbatim across three independently read source snapshots (hashes confirmed against manifest). No suspicious patterns. No dependency on the two excluded 403 domains (openai.com, axios.com). Cross-reference to the May GPT-5.5-Cyber article resolves to a real, relevant prior article, and the follow-up framing is substantively earned by new facts in this release. No originality conflicts with recently published coverage. APPROVE.
