Microsoft 365 Copilot Notebooks mind maps are now showing up as a real rollout signal, not just a preview note: the June notebook update says Copilot Notebooks are expanding to Copilot Chat users, while the dedicated mind-map support page says mind maps are available in Copilot Notebooks with node summaries and an Explain flow. Reddit’s reaction is treating this as a genuine GA milestone. Sources: Reddit ; Microsoft blog ; Microsoft support
Custom engine agents in Microsoft 365 Copilot Chat still cannot reliably handle file or image attachments. A fresh TechCommunity thread says there is no supported workaround yet, Microsoft’s known-issues page still says users can’t upload files in agent chats and agents can’t return files for download, and the thread cites Microsoft confirmation that this is a platform shortage with no published ETA.

GitHub Copilot model routing remains uneven across surfaces: a current r/GithubCopilot thread says DeepSeek can be used in the VS Code chat panel and Copilot CLI, but not in the VS Code Agents window picker. That is another reminder that Copilot’s agent surfaces still do not expose the same model list or routing behavior. Source: Reddit
HN’s newest agent-tooling thread is “Have your agent consult other models,” which ships the idea as consult-llm: a second-opinion tool for existing agent workflows with local/cloud backends, multi-turn threads, diff context, and a live monitor. Sources: HN ; GitHub
Another HN item, “Loom, an open-source delivery harness for coding agents,” pushes the same broad category forward from a different angle: it wraps existing coding agents in a structured delivery loop of planning, building, verification, repair, preview, and handoff instead of pretending the model alone is the product.
