AI: OpenAI Snatches International Contracts, Anthropic Awaiting Trump's Green Light
OpenAI has officially gained an advantage over Anthropic in the field of AI-powered cybersecurity. Its GPT-5.5 Cyber model reaches 85.6% on CyberGym, compared to 83.8% for Mythos 5. While Anthropic remains faced with a suspension imposed by US authorities, OpenAI is multiplying international partnerships and expanding its Daybreak program. This momentum could strengthen its global influence in the strategic sectors of cybersecurity and artificial intelligence.

In brief
- GPT-5.5 Cyber outperforms Claude Mythos 5 by 14% in the latest resilience benchmarks against state-sponsored cyberattacks.
- OpenAI’s AI is establishing itself with the governments of the UK, Japan, and Australia through exclusive G2G contracts.
- Anthropic faces a strict US Department of Commerce export block on its Claude Mythos 5 model.
- The rivalry between OpenAI and Anthropic now goes beyond technology to touch geopolitics.
GPT-5.5-Cyber: the AI model that goes beyond the ban
On June 22, 2026, OpenAI officially launched the full version of GPT-5.5-Cyber as part of its Daybreak program. The announcement came just days after the suspension of Anthropic’s Fable 5 and Mythos 5 for foreign users.
On CyberGym (a benchmark that subjects AI agents to 1,507 known software vulnerabilities from 188 open source projects), GPT-5.5-Cyber achieves 85.6%, compared to 81.8% for standard GPT-5.5. According to OpenAI, this score represents the best performance ever measured on this test for an individual model.
Anthropic’s Mythos 5, however, caps at 83.8% on the same ranking while Claude Opus 4.7 stops at 73.1%. The gap between GPT-5.5-Cyber and Mythos 5 may seem modest on paper: less than two percentage points. But this should not be seen as a mere statistical result. According to analysts, it represents a major strategic break.

Same result on two other demanding AI benchmarks:
- GPT-5.5-Cyber scores 39.5% on ExploitGym which tests the ability to turn known vulnerabilities into operational exploits, versus 25.95% for GPT-5.5.
- On SEC-bench Pro, which evaluates flaw discovery on complex targets, GPT-5.5-Cyber reaches 69.8%, compared to 63.1% for standard GPT-5.5.
These figures establish GPT-5.5-Cyber not as an incremental refinement but as a generational shift in defensive AI.
OpenAI accelerates its global AI conquest through the Daybreak program
After closing a record funding round, OpenAI is multiplying performances. It has notably established Trusted Access for Cyber partnerships with:
- Australia;
- Canada;
- France;
- Germany;
- Japan;
- South Korea;
- European Union institutions (including the EU Agency for Cybersecurity or ENISA).
These agreements allow these governments to access OpenAI’s most advanced defensive AI capabilities to protect their critical infrastructures.
On the commercial front, 28 security companies have joined the Daybreak Cyber Partner Program. Among them are:
- CrowdStrike;
- Cisco;
- Cloudflare;
- Palo Alto Networks;
- SentinelOne;
- Wiz.
They will now be able to integrate GPT-5.5 into their products for verified clients.
In addition to preparing the biggest transformation of ChatGPT, OpenAI has also launched Patch the Planet, an AI initiative founded with Trail of Bits, in collaboration with HackerOne and Calif. The goal: to help massively used open source projects (including cURL, Go, Python, and Sigstore) move from vulnerability detection to effective correction.
Donald Trump’s arbitration: Anthropic’s last hope
While OpenAI celebrates its international partnerships, Anthropic’s offices endure the constraints of the technological cold war just days after launching its latest AI model: Fable 5.
Although praised by the AI developer community for its exceptional logical reasoning abilities, its Claude Mythos 5 model has been classified as “highly sensitive dual-use technology” by the US Department of Commerce. Result: a strict export ban outside US soil.
Regulators fear that the power of AI Claude Mythos 5 could be diverted by rival powers for cyber destabilization purposes. Immediate consequence: Anthropic had to freeze its commercial negotiations in Europe and Asia.
The loss is colossal for the startup funded by Amazon and Google, which sees OpenAI capture the most profitable segments of the global public sector without being able to offer any commercial resistance.
One thing is certain: dominance in AI no longer depends solely on model quality. Political and regulatory decisions now directly influence competition between industry players. The next stage to watch remains the regulatory verdict on Anthropic and how quickly OpenAI consolidates its positions before any comeback of competition in the artificial intelligence market.
