The video explains how routing strategies like single, cascade, and critique workflows can automatically choose an execution path per task to improve outcomes without manual model selection.

GitHub shares a quick “The Download” roundup covering a new GitHub CLI capability for attaching images and videos to pull requests, plus several AI-related updates including local coding-agent models, large-scale LLM releases, and benchmarks and analyses focused on AI code review and PR-writing language.

GitHub explains the “AI harness” concept for guiding LLM execution, and how harness engineering adds the runtime, tools, and guardrails that let AI agents work safely against a codebase in agentic workflows.

GitHub’s podcast episode with Cassidy, Marlene, and GPS breaks down emerging AI terms—loop engineering, harness engineering, and squads—and connects them to practical agentic workflows, including how iteration loops affect cost and performance and how “open weight” differs from truly open source AI.

GitHub hosts a multi-hour Copilot Day live session covering new releases, hands-on demos, and practical workflows, including how Copilot works across GitHub, the CLI, and VS Code, plus a live-coding segment with Burke Holland, Pierce Boggan, and guests.

GitHub introduces a GitHub CLI update that lets developers attach local images or videos to issues, pull requests, and comments using a repeatable --attach flag, making it easier to share visual context directly in GitHub discussions.

GitHub runs a beginner-friendly virtual training on the GitHub Copilot SDK, focusing on how developers can programmatically interact with Copilot and build custom agent capabilities that fit their team’s workflows across multiple languages.

GitHub introduces canvases in the GitHub Copilot app and shows how beginners can use the /create-canvas skill to generate custom, interactive workflow surfaces like release checklists, kanban boards, and triage views, then iterate on them and share state in real time.

GitHub explores the GitHub Copilot Teams integration with Slack, focusing on how teams can bring Copilot into their existing collaboration workflow.

GitHub shows how the GitHub Copilot app’s built-in diff, terminal, and browser panels help you review and validate AI agent-made changes without constantly switching tools, so you can keep a tighter loop before accepting code updates.

GitHub interviews the maintainers of the Zephyr Project as part of Open Source Friday, focusing on what Zephyr is and why it’s positioned as a scalable, optimized, and secure RTOS across multiple hardware architectures.

GitHub shares a changelog update for OAuth apps, covering refresh tokens, access token lifetimes, and support for multiple callback URLs. It also highlights configuration details like the offline_access scope and a security audit tip for legacy wildcard redirect URI matching.

GitHub shares a weekly developer-news roundup covering GitHub Universe 2026 updates, changes to GitHub OAuth apps (refresh tokens and multiple callback URLs), and security-related notes like Cloudflare detecting MCP traffic, plus a couple of project picks for local AI and terminal animations.
