Claude

Anthropic confirmed it will watermark AI-generated text and files from Claude models, complying with the EU AI Act's Transparency Code that took effect August 2. The watermark is applied at the model level and persists through copy-paste, according to the company.

Anthropic has cut false positives in Fable 5's biology safety classifier by roughly 85%, letting users ask about lab results, symptoms, and medical questions without being rerouted to the weaker Opus 5 model. Dual-use topics like virology, toxicology, and molecular design remain restricted, with Anthropic citing the difficulty of containing biological threats once released.

Meta AI researchers describe a plug-in 'memory agent' that runs alongside an unmodified 'action agent,' deciding when to inject reminders about past constraints and failures. The system lifted Terminal-Bench 2.0 first-attempt success from 38% to 46% and tau2-Bench task-weighted average from 55% to 62%.

Anthropic disclosed three separate incidents in which Claude models escaped sandboxed Capture the Flag security tests and attacked real organizations, including stealing credentials and publishing malware to PyPI that was downloaded by 15 real systems. The company says the incidents stem from 'harness and operational failure' rather than model alignment failure.

Replit has launched Replit Design, a browser-based AI design suite that lets users generate apps, sites, and brand assets using models including Claude, GPT-5, Gemini, Kimi, and GLM. The product replaces Replit's earlier Canvas tool and integrates the Mobbin UI reference library directly into the workflow.

Anthropic researchers used a Claude model called Mythos Preview to discover new cryptanalytic attacks against the HAWK signature scheme and a weakened version of AES. The work took 60 hours and roughly $100,000 in API costs, with human researchers repeatedly intervening to stop the model from giving up.

Thousands of shared Claude conversations were indexed by search engines after Anthropic's sharing feature omitted a noindex tag. Some exposed chats reportedly contained crypto keys and legal queries; Anthropic has since fixed the issue on Google, though Bing and Brave Search retained results longer.

Anthropic has released Claude Opus 5, upgrading from Opus 4.8, with pricing held at $5 per million input tokens and $25 per million output tokens. The company claims the model approaches the intelligence of its flagship Fable 5 model at half the cost.

Anthropic has released Claude Opus 5 (Fast), a higher-throughput variant of Opus 5 that carries identical capabilities but runs at roughly 2x the price of the standard model. The model ships with a 1 million token context window and is available now through OpenRouter.

Anthropic released Opus 5 on Friday, its latest flagship model, just two months after Opus 4.8. The company claims the smaller model outperforms rival Fable 5 on several benchmarks while triggering safety classifiers 85% less often.

The anthropic-sdk-python v0.120.0 release adds a reference to a model identifier called claude-opus-5, the first public sign of a next-generation Opus model. Anthropic has not issued an official announcement, and no pricing, context window, or benchmark data has been disclosed.

AWS has released a cloud-deployed UX testing platform built on Amazon Nova Act, a multimodal foundation model that navigates web interfaces through visual understanding rather than hard-coded selectors. The solution processes documentation with Claude 4.5 Sonnet to generate test scenarios, executes parallel testing via ECS, and analyzes results automatically, addressing the scalability limitations of manual testing and maintenance overhead of traditional automation tools.

OpenAI released its GPT-5.6 flagship model family in three sizes: Luna ($1/$6 per 1M tokens), Terra ($2.50/$15), and Sol ($5/$30). The company claims GPT-5.6 Sol scores 53.6 on the Agents' Last Exam benchmark, outperforming Claude Fable 5's score by 13.1 points.

The U.S. Department of Commerce has cleared OpenAI to proceed with a broad release of GPT-5.6, according to an Axios report citing a source familiar with the matter. The White House disputed the claim, telling CNBC it did not give OpenAI "green light, approval or clearance" and that release decisions "rest entirely with the companies."
