Hark, the secretive AI startup founded earlier this year by serial entrepreneur and roboticist Brett Adcock, today announced Handoff, a "computer use agent" (CUA) that it says is among the top-performing in the world at navigating the open web on a user's behalf — ordering dinner on DoorDash, booking flights on United and Delta, or messaging job candidates on LinkedIn — all autonomously, end-to-end.
WorldofAI explores the capabilities of this large-scale model, focusing on its performance in coding, research, and long-horizon reasoning. The review examines its multimodal functionality and utility in generating 3D assets, web applications, and interactive simulations, while demonstrating the test-sprite CLI tool as a mechanism for verifying agent-driven code outputs.
The @cloudflare/computer package provides an agent runtime where the details and mechanics of what code runs in an isolate, a container sandbox, or a web browser are handled by the platform. Each agent gets a computer, the runtime optimizes for efficiency, and scalability.
Boris Churnney explains strategies for optimizing AI agent workflows, emphasizing why clearing outdated setup files and prompts is crucial when new models are released. Learn how to refine project management by implementing strict evaluation checks, utilizing effective coding habits, and balancing automation with manual oversight to ensure better results from intelligent systems.
In this video, Sam Witteveen looks at ThinkingCap, a fine-tune of the Qwen3.6-27B model. BottleCap's goal was intentionally conservative: do not try to make the model smarter or teach it new capabilities. They wanted to preserve knowledge, reasoning ability, answer quality, conversational style, instruction following, and safety behavior.
The only thing they wanted to change was the amount of computation spent reaching an answer. In other words: keeping the same model, and making sure it overthinks less.
AI LABS explores the technical shift from loop engineering to graph engineering in AI workflows. This guide details how to implement robust verification strategies, skill orchestration, and browser-based testing to improve agent reliability and manage complex task outputs effectively.
Fresh off the launch of Opus 5, Claude Code creator Boris Cherny joins Diana Hu at Startup School 2026 to talk about what the newest models can do, how Claude Code came to be, and what it means to build products when the underlying capabilities keep accelerating.
