What is Ably?
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
What is incident.io?
incident.io now drafts status page updates with AI while the team edits together.
incident.io's center is Investigations, the agent that posts a root-cause hypothesis when an incident opens. October pushed its skills into coding harnesses and opened Nexus to customers' own tools. November turns to incident communications: the 11-03 release set org-wide guidance for how summaries and updates are written, and the 11-10 release lets a team draft status page updates together, with an AI first draft.

7.5INFRA · APIS
Ably's AI Transport hits 1.0 and plugs straight into Vercel's useChat with resumable streams.
◆ Current state
Ably is repositioning its realtime pub/sub network as the transport layer for AI agent output. AI Transport JS 1.0 runs on ordinary Pub/Sub channels and ships adaptors for the Vercel AI SDK, OpenAI Responses API and AG-UI, plus a useChat transport that resumes a stream after a reload. It lands a week after the switch to monthly-active-user pricing and breaking SDK majors that split every client into device and server packages.
◆ Where it's heading
The November releases fit one plan: split clients so MAU billing can count end users, then make the AI layer a thin adaptor on top of the same channels used for chat, presence and LiveObjects. Server-side additions in Java and JS (HTTP LiveObjects, channel pools, a Temporal plugin) point at agent backends as the intended publisher.
◆ Prediction
Expect more agent framework adaptors and server SDKs reaching AI Transport parity, with Chat and LiveObjects examples built around agents joining human conversations.
incident.io
7.5INFRA · APIS
incident.io now drafts status page updates with AI while the team edits together.
◆ Current state
incident.io's center is Investigations, the agent that posts a root-cause hypothesis when an incident opens. October pushed its skills into coding harnesses and opened Nexus to customers' own tools. November turns to incident communications: the 11-03 release set org-wide guidance for how summaries and updates are written, and the 11-10 release lets a team draft status page updates together, with an AI first draft.
◆ Where it's heading
After a month of agent extensibility, the AI is moving into the outward-facing part of an incident: what customers read. The guidance control and the shared drafting fit together, the first setting the tone and the second putting AI drafts in front of the people who approve them.
◆ Prediction
Expect more of the incident write-up flow, such as post-mortems or customer emails, to start from AI drafts governed by the same org-wide guidance.
