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 Microsoft Azure?

Azure flips a stack of preview-to-GA promotions while quietly retiring a long tail of legacy VM reservations.

Azure is wrapping up several preview-to-GA arcs at once. Elastic SAN gained three GA capabilities in a single drop (single volume snapshots, AVS Gen2 Private Cloud support, AV64 SKU support), AKS got Application Gateway for Containers as a managed add-on in AKS Automatic, and Azure Functions added Java 25 support and a Consumption SKU for the Durable Task Scheduler aimed at AI agent orchestration. On the lifecycle side, one-year Reserved VM Instance purchases retire on July 1, 2026 across 14 legacy VM series.

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

Azure flips a stack of preview-to-GA promotions while quietly retiring a long tail of legacy VM reservations.

◆ Current state

Azure is wrapping up several preview-to-GA arcs at once. Elastic SAN gained three GA capabilities in a single drop (single volume snapshots, AVS Gen2 Private Cloud support, AV64 SKU support), AKS got Application Gateway for Containers as a managed add-on in AKS Automatic, and Azure Functions added Java 25 support and a Consumption SKU for the Durable Task Scheduler aimed at AI agent orchestration. On the lifecycle side, one-year Reserved VM Instance purchases retire on July 1, 2026 across 14 legacy VM series.

◆ Where it's heading

Azure is doing two things in parallel. It's compressing storage and networking previews into GA so AVS, AKS, and Elastic SAN converge into a more coherent enterprise platform. And it's pruning the back catalog — older VM series losing reservation eligibility and ACS forcing migration off legacy AlternateId — clearing the deck for a tighter set of supported configurations.

◆ Prediction

Expect more legacy SKU retirements through the year as Azure consolidates around current VM families. The Durable Task Scheduler Consumption SKU is positioned squarely for agent orchestration, so look for tighter integration between Azure Functions, AI Foundry, and the agent runtimes that have been shipping recently.
