SAE-based safety measures are vulnerable to post-intervention recovery: models can restore suppressed behaviors even when targeted features are controlled.
Sumi is the first openly available Uniform-Diffusion language model trained from scratch at the 7-billion-parameter scale and addresses a research gap between established autoregressive and masked diffusion approaches.
AI-driven code generation makes code practically costless, upending traditional software development economics and demanding higher engineering discipline.
Bedrock AgentCore connects agents with three layers of knowledge (enterprise, web, paid data sources) and mechanisms for productive monitoring and optimization without requiring teams to operate their own data pipelines.
RepSelect isolates forget-set-specific representations through selective gradient component collapsing and achieves 4-50x greater robustness against relearning attacks than existing methods.
Attackers could pre-register cloud storage buckets based on predictable naming schemes derived from project ID and region to replace uploaded models with malware before Vertex AI loaded them.
Copilot Cowork is now generally available and allows users to choose between models from Anthropic (Claude Opus 4.8, Sonnet 4.6) as well as GPT 5.5 in the Frontier program.
