OpenAI models, Codex, and Managed Agents come to AWS
OpenAI has expanded its AWS partnership to bring GPT models, Codex, and its Managed Agents offering directly into AWS environments, allowing enterprises to deploy these services without data leaving their existing cloud infrastructure. This gives AWS customers native access to OpenAI's agent orchestration layer alongside standard model APIs, positioned as a secure enterprise deployment path. The move deepens the competitive dynamic with Amazon's own Bedrock and Anthropic, which has a long-standing AWS partnership.

Introducing NVIDIA Nemotron 3 Nano Omni: Long-Context Multimodal Intelligence for Documents, Audio and Video Agents
NVIDIA released Nemotron 3 Nano Omni, a compact multimodal model designed for agent workloads involving long-context document, audio, and video understanding. The model targets on-device and edge deployment scenarios where a small footprint matters but cross-modal reasoning over extended contexts is required. Its release on HuggingFace suggests open or accessible weights, making it relevant for practitioners building document and media processing pipelines.

The Power of Power Law: Asymmetry Enables Compositional Reasoning
This paper challenges the common assumption that uniform data distributions improve learning of rare skills, showing that training under natural power-law distributions consistently outperforms uniform distributions on compositional reasoning tasks like state tracking and multi-step arithmetic. The authors introduce a theoretical framework demonstrating that power-law sampling requires substantially less training data to achieve the same compositional generalization. The result has direct implications for data curation strategies in pre-training and fine-tuning pipelines.
