What is Presto?
Presto ships steadily, but the feed carries only version numbers and a link.
Presto is releasing on its usual cadence - 0.299 in late August, 0.298 and a 0.298.1 patch in June, 0.297 in April. What is shipping in them cannot be determined from this feed: every entry is a version number and a pointer to release notes hosted elsewhere, with no body text at all.
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.
Presto vs Ably: editorial side-by-side
Presto
2.5INFRA · APISANALYTICS
Presto ships steadily, but the feed carries only version numbers and a link.
◆ Current state
Presto is releasing on its usual cadence - 0.299 in late August, 0.298 and a 0.298.1 patch in June, 0.297 in April. What is shipping in them cannot be determined from this feed: every entry is a version number and a pointer to release notes hosted elsewhere, with no body text at all.
◆ Where it's heading
The only readable signal is tempo, and tempo is steady rather than accelerating: roughly one minor release per two months, with point releases when a fix cannot wait. The project's direction, breaking changes, and connector work are all invisible here.
◆ Prediction
Cadence suggests 0.300 lands within about two months. Nothing in this feed supports a claim about what will be in it - the release notes would have to be read directly.
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.
