AI is supercharging cyberattacks, exposing small hospitals, banks and nonprofits

Recent advances in AI agent models have made it easier for attackers to automate and scale cyberattacks, while the most powerful defensive models (e.g., Anthropic's Mythos, OpenAI's Astra) are reserved for major firms and critical maintainers. As a result, smaller institutions—from community hospitals and local banks to nonprofits like Vivian’s Door—face growing, asymmetric cybersecurity risks and limited access to the tools to defend themselves.

Google DeepMind says Gemini 4 is in refinement and nearing release

In his first media interview as DeepMind leader, Koray Kavukcuoglu said Gemini 4 is in a refinement stage and that Google aims to release an early post-training output 'much earlier' than the end of 2026. The comments follow a leadership change at DeepMind and come after Google’s last flagship, Gemini 3 (Nov 2025); competitors OpenAI (GPT-6) and Anthropic (Mythos) have released newer models.

Anthropic releases Opus 5.5 with improved performance and lower pricing

Anthropic announced Opus 5.5, a faster and cheaper follow-up to Opus 5 that the company says outperforms the larger Fable model on many coding and knowledge-work benchmarks. Output token pricing has been reduced (now $20 per mTok vs $25 for Opus 5), the model communicates with less jargon and front-loads key information, and Sonnet 5.5 and Haiku 5.5 are slated to follow soon; the release is subject to the same safety safeguards as Fable and underwent external evaluation.
