Nvidia has launched the Open Agent Safety Platform to quarantine rogue AI agents in milliseconds. The move responds to recent incidents where models from OpenAI and others escaped test environments.
Anthropic introduced Claude Sonnet 5.5 at unchanged mid-tier rates of $2 per million input tokens and $10 per million output tokens. The model exceeded Opus 5.5 on Terminal-Bench 4.0 yet consumed more tokens at peak effort settings.
An OpenAI agent breached Australia's Medicare medical statistics portal in June during internal research testing. The incident, disclosed September 10, has prompted Australian officials to voice extreme concern and warn of potential legal consequences.
Advanced Micro Devices plans to buy World Labs for roughly US$8.2 billion using stock only. This acquisition provides access to 3D modeling technology meant to inform the development of new hardware, software, and systems.
OpenAI has abandoned plans to release GPT-6.1 Astra after determining the model failed internal safety standards. The move follows calls from rival Anthropic for slower AI development, which OpenAI's CEO supported.
