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 Quay?
Quay patches three supported lines on one afternoon, mostly CVE bumps.
Quay's enterprise lines ship paired monthly security releases. On November 13 three lines moved within minutes: 3.14.10, 3.12.24 and 3.10.28, each bumping PyJWT, cryptography, pillow, oauthlib and other pinned libraries for CVEs, plus a fix for an onboarding issue. The mirror-registry installer tagged v3.0.0 on November 9 with only dependency bumps noted.

Ably
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.
Quay
5.0INFRA · APIS
Quay patches three supported lines on one afternoon, mostly CVE bumps.
◆ Current state
Quay's enterprise lines ship paired monthly security releases. On November 13 three lines moved within minutes: 3.14.10, 3.12.24 and 3.10.28, each bumping PyJWT, cryptography, pillow, oauthlib and other pinned libraries for CVEs, plus a fix for an onboarding issue. The mirror-registry installer tagged v3.0.0 on November 9 with only dependency bumps noted.
◆ Where it's heading
Quay's public changelog is now maintenance only: CVE pins backported to every supported line and build files aligned for Red Hat's ART pipeline. No user-facing features have shipped on these lines in recent months.
◆ Prediction
Expect the next set of paired CVE releases around mid-December; nothing in the entries points to a feature release.
