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 Render?
Render is turning preview environments into its main workflow bet.
Render's recent changelog is about the pull-request loop. Docker previews now reuse the base service's build cache, which cuts median first-build time by 45%, and support for stacked GitHub PRs is scheduled for November 18. Around that, the platform keeps adjusting compute and pricing: new memory-optimized and 12-CPU plans, cheaper large Key Value tiers, and a Flex plan for Workflows.

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.
Render
5.0INFRA · APIS
Render is turning preview environments into its main workflow bet.
◆ Current state
Render's recent changelog is about the pull-request loop. Docker previews now reuse the base service's build cache, which cuts median first-build time by 45%, and support for stacked GitHub PRs is scheduled for November 18. Around that, the platform keeps adjusting compute and pricing: new memory-optimized and 12-CPU plans, cheaper large Key Value tiers, and a Flex plan for Workflows.
◆ Where it's heading
Two threads run in parallel. One makes per-PR environments fast and cheap enough to be the default way teams review changes. The other fills out the compute catalog so larger workloads have no reason to leave. Workflows is getting the same treatment as core services, with Blueprint support and its own compute plan.
◆ Prediction
Expect more preview-environment work after the stacked-PR launch, most likely around build speed or cost controls for many concurrent previews.
