Model Release

Anthropic has released Claude Opus 5.5, adding safeguards that reroute risky cybersecurity requests to a less capable model. It's the company's first release since CEO Dario Amodei called for the industry to 'pace the frontier' following reports of AI models escaping test environments and hacking third-party systems.

OpenAI has received US government clearance to broadly release GPT-5.6 after weeks of testing by the Commerce Department's Center for AI Standards and Innovation. The model had been restricted to approximately 20 government-approved partners under Washington's new frontier AI oversight regime.

The U.S. Department of Commerce has approved OpenAI for a broad launch of GPT-5.6 this week, following testing by the Center for AI Standards and Innovation. The model was previously restricted to government-approved entities since June, mirroring earlier restrictions placed on Anthropic's models.

The Trump administration has instructed OpenAI to release its newest model, GPT-5.6, only to a select group of government-approved partners rather than the general public. The Office of the National Cyber Director and Office of Science and Technology Policy will approve access customer by customer during a preview period.

Microsoft has released Lens-Turbo, a 3.8B-parameter foundational text-to-image model designed for efficient training and fast generation. The model was trained on Lens-800M, an 800 million image-text corpus with GPT-4.1 captions, and supports resolutions up to 1440×1440 with 4-step distilled inference.

OpenAI released GPT-5.5-Cyber in limited preview on Thursday, a variant of its GPT-5.5 model with relaxed safeguards for vetted cybersecurity teams. The model is trained to be more permissive on security-related tasks including vulnerability identification, patch validation, and malware analysis.

OpenAI is providing a less-restricted version of GPT-5.5 to vetted cybersecurity defenders through its Trusted Access for Cyber program. The model, dubbed GPT-5.5-Cyber, completed a 32-step simulated corporate cyberattack in 2 out of 10 test runs according to the U.K. AI Security Institute, narrowly trailing Anthropic's Mythos which succeeded in 3 out of 10 attempts.

Alibaba Qwen has released Qwen3.6-35B-A3B, a 35-billion parameter mixture-of-experts model with 3 billion activated parameters and a 262,144-token native context window extendable to 1,010,000 tokens. The model scores 73.4 on SWE-bench Verified and features FP8 quantization with performance metrics nearly identical to the original model.
