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 Payload CMS?

Payload's v4 beta.9 keeps every past image crop and raises the Node floor again.

Payload has tagged nine v4 betas since October 10. Beta.9 reads saved crops and focal points from the new _transforms store, serves historical upload variants when a version is restored, adds labels and device details to sessions, and exports standalone CSS tokens from the UI package. It also bumps the minimum Node version to 24.22.3, the second Node floor raise in the cycle.

7.5

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.

5.0

Payload's v4 beta.9 keeps every past image crop and raises the Node floor again.

◆ Current state

Payload has tagged nine v4 betas since October 10. Beta.9 reads saved crops and focal points from the new _transforms store, serves historical upload variants when a version is restored, adds labels and device details to sessions, and exports standalone CSS tokens from the UI package. It also bumps the minimum Node version to 24.22.3, the second Node floor raise in the cycle.

◆ Where it's heading

Three betas in a row have reworked file uploads around one stored original plus replayable transforms, and two have tightened sign-in and sessions. The v4 cycle is now finishing those two systems rather than adding new surfaces, which is the usual shape of a beta nearing a release candidate.

◆ Prediction

Expect more betas that close out the transforms and session work, with a release candidate once the fix lists shrink; the entries do not show a date.
