Claude Opus 4.5 scores higher than its rivals in prompt-injection security, but the results show how limited these defenses still are. A benchmark by the security firm Gray Swan found that a single "very strong" prompt injection attack breaks through Opus 4.5's safeguards 4.7 percent of the time. Give an attacker ten attempts and the success rate jumps to 33.6 percent. At 100 attempts, it reaches 63 percent. Even with those gaps, Opus 4.5 still performs better than models like Google's Gemini 3 Pro and GPT-5.1, which show attack rates as high as 92 percent.
Amazon has announced a major investment in its AI footprint for federal work, saying it will spend up to $50 billion to expand AI and supercomputing infrastructure for U.S. government agencies. The project supports the U.S. government’s AI Action Plan and is expected to help agencies accelerate discovery, decision-making, and mission workflows, including through faster analysis and automation.
Amazon’s investment underscores the strategic importance of AI and supercomputing in maintaining technological superiority, safeguarding critical infrastructure, and driving industrial innovation.
Starting in 2026, AWS plans to add nearly 1.3 gigawatts of new compute capacity across its Top Secret, Secret, and GovCloud (US) regions. Once live, agencies will be able to use services such as SageMaker, Bedrock, Trainium chips, and Anthropic models to build their own AI applications, speeding up data analysis and improving workflows in areas like cybersecurity, healthcare research, and autonomous systems.
Google has added a slide generator to NotebookLM, giving users a quick way to turn their sources into simple slide decks. The tool can help structure notes or produce early drafts, and Google says it can also enhance existing slides visually.
Right now, NotebookLM delivers slides only as PDFs. Export options for Google Slides and PowerPoint are in development, Google says. The feature is available immediately, with daily usage limits based on the user's account.
