GitHub / 14 OctExisting-product update
HydraFusion Max
Copilot combines multiple models into one response; Max is a higher-effort preview option.
What changed
What’s new
GitHub introduced Max, step-specific reasoning effort, conditional judging in Cascade and parallel workspace-aware critics in Critique.
Why it matters
Compare verified code quality, runtime and cost with a single-model approach before upgrading.
Access Research preview for eligible paid Copilot plans in VS Code, Copilot app and CLI, with preview enabled.
Primary source ↗02Open source. Ready to explore.
Repositories with a reason to watch or try them.
The software is open source. Model access and hosted services can carry separate costs.
14 Oct / Technical previewMIT New capabilityA GitHub CLI extension records exact commits for Actions workflow dependencies.
What changed + how to try
What’s new
Public-preview lockfiles let reviewed workflow references resolve to fixed commits even if tags move.
Why it matters
Reduce unexpected CI code changes; a pinned malicious dependency remains unsafe.
Try it
Install GitHub CLI and the extension in a disposable repository; no model API required.

TODAY’S EXPERIMENT · 20–30 minutes after setupTry github/gh-actions-lock: audit CI dependencies
Generate and inspect an Actions dependency lockfile in a disposable repository, then verify the recorded pins.
Why it helps Learn whether the CI actions an agent executes match the commits a reviewer approved.
