The morning view

Agents gain more ways to work through conversations and email, while new reporting fields help teams understand model usage and evaluation results. Preview requirements, metered costs and opt-in settings still shape access.

1. GitHub brings notifications and Copilot into one Teams app

Development:

GitHub consolidated notifications and Copilot in its Teams app on October 23. An issue alert can lead to an agent-generated pull request for people to review and test. Existing GitHub notifications users should update; legacy GitHub app users must switch before its November 16 retirement.

The integration remains in public preview. It requires a paid Copilot plan, enabled cloud sandboxes, Teams app-install permission and Microsoft Public Developer Preview. Only repository writers can trigger changes; workspace guests and outside collaborators cannot start or steer sessions. The full thread becomes agent context, stored in generated artifacts. Cloud sandbox use incurs usage charges.

Our read: Has teeth. The consolidation reduces the handoff between discussing a bug and commissioning a reviewable fix, for teams meeting the preview requirements.

2. OpenAI’s Decisions API leaves beta with larger requests

Development:

OpenAI made its Decisions API generally available on October 22. Using GPT-6 Luna, it returns probabilities, fixed-choice answers or scores for tasks such as routing requests. The update supports 400 questions per request, up from 200 in beta, alongside shared-input caching, structured JSON inputs and images within individual questions.

Uncached input costs $0.10 per million tokens; output tokens are uncharged. Cache writes cost extra, and regional and long-context premiums apply. Only GPT-6 Luna is supported. Decisions selects answers; the application still executes any resulting action. Questions that depend on earlier answers require separate requests.

Our read: Has teeth. A higher question limit and reusable input give developers concrete options for evaluating several criteria against the same evidence.

3. Resend gives agents and people shared email threads

Development:

Resend launched Inboxes on October 22, extending its email infrastructure with shared conversation threads, assignments, notes and drafts. Developers can connect their own agents through the API, command-line tools or MCP, the protocol for connecting AI tools to services. Built-in agents can also triage email under configured instructions and allowed actions.

Inboxes use addresses on your domains. Every plan includes three; additional inboxes cost $1 each per month on paid plans with pay-as-you-go enabled. There is no separate email allowance: both incoming and outgoing inbox messages consume the transactional quota.

Our read: Has teeth. Developers can build on shared conversation state instead of implementing the whole inbox around incoming-email webhooks.

4. Copilot’s usage API starts counting traffic from more clients

Development:

GitHub added client-level model traffic to its Copilot usage metrics API on October 23. The breakdown includes tools such as OpenCode whose activity could be missing from editor-based reporting. Enterprise and organization reports, including per-user versions, show successful requests, sessions and token usage by client. Request and token metrics also have a model breakdown.

Access requires the usage-metrics policy to be enabled and an eligible owner, billing-manager or custom metrics-viewing role. Request counts measure model calls, not prompts: one prompt may trigger several calls. Client names come from supplied integration identifiers and are best-effort labels, not verified identities.

Our read: Has teeth. Counting traffic on the server closes a documented reporting gap, helping administrators compare reported client usage without mistaking it for productivity.

5. Langfuse exports the origin of evaluation scores

Development:

Langfuse added optional score metadata and provenance to scheduled storage exports on October 22. Teams can include identifiers for the reviewer, evaluation configuration, queue or automated evaluator behind a score. An execution-trace identifier links an AI judge’s verdict to the run that produced it, making warehouse analysis easier to investigate.

The two field groups are off by default and affect future exports only. The underlying export feature supports Amazon S3, Google Cloud Storage and Azure Blob Storage. It is available for self-hosted deployments and Enterprise, or Pro with the Teams add-on; Hobby and Core do not include it.

Our read: Has teeth. Preserving who or what assigned a score helps teams investigate disagreement instead of treating every evaluation number as equivalent.
