NVIDIA Nemotron 3 Super, a hybrid Mixture of Experts model with 120B parameters and 12B active parameters, is now available as a fully managed model on Amazon Bedrock. The model supports up to 256K token context length and claims 5x higher throughput efficiency over the previous Nemotron Super and 2x higher accuracy on reasoning tasks.

OpenAI is consolidating its fragmented macOS app ecosystem by merging ChatGPT, Codex coding platform, and Atlas browser into a single "superapp" led by Chief of Applications Fidji Simo. The unified app will feature agentic AI capabilities for autonomous task execution and team collaboration, with rollout expected over coming months starting with Codex enhancements.

Perplexity has released Comet, its AI-powered browser, as a free standalone app for iPhone users. Originally launched on PC at $200 per month, the iOS version joins recently-released Android and existing Windows and Mac versions. The browser combines web browsing with AI assistance for summarization, research, and task automation.

Amazon Nova 2 Lite expands context window to 1 million tokens, introduces extended thinking with developer controls, and adds native tool use and web grounding. AWS claims Nova 2 Lite surpasses Nova 1 Pro on multi-step reasoning while costing 7x less and running up to 5x faster.

GitHub has released the Copilot SDK, positioning executable agent workflows as the successor to prompt-based AI interactions. The SDK enables developers to integrate agentic AI capabilities directly into applications rather than relying on text-based prompt-response patterns.

GitHub is positioning AI interaction as a shift from prompt-response text interfaces to programmable execution models. The company announced a GitHub Copilot SDK that enables agentic workflows to run directly within applications, marking a transition toward AI systems that take concrete actions rather than generate text responses.

OpenAI's GPT-5.4, an agentic coding model, is now generally available in GitHub Copilot. The model was tested on real-world software development scenarios and demonstrated improved coding capabilities.

OpenAI has launched GPT-5.4, its latest model with native computer use capabilities that allow it to operate computers and complete tasks across applications. The release represents a step toward autonomous AI agents that can handle complex jobs independently. The model includes advancements in reasoning, coding, and professional work with spreadsheets, documents, and presentations.

American International Group (AIG) has deployed an agentic AI system with an orchestration layer, reporting faster-than-expected productivity gains in underwriting and portfolio management. The deployment demonstrates measurable improvements in throughput and workflow efficiency, according to recent investor disclosures.
