H Company releases Holotron-12B, a multimodal computer-use agent optimized for high-throughput inference using a hybrid SSM architecture. The model, post-trained on NVIDIA Nemotron, demonstrates superior efficiency and scalability for interactive agentic workloads.
OpenAI released the Operator System Card detailing safety evaluations for its Computer-Using Agent (CUA) model, which combines GPT-4o's vision capabilities with reinforcement learning to interact with GUIs and perform web-based tasks on users' behalf. The card outlines risk areas including prompt injections, harmful tasks, and model mistakes, along with multi-layered mitigations based on OpenAI's Preparedness Framework.
