What is Redocly?

Redocly lets docs teams filter AI assistant chats by the visitor's team.

Redocly's Platform keeps building out analytics for its docs AI assistant. After question categories on November 10 and an Answer found filter on November 11, a November 12 release adds the visitor's teams to each conversation, with a team filter, email search and a matching CSV column. The rest of the week was fixes: hardened access control for hosted projects, Git outage handling and Respect Monitoring runs.

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.

5.0

Redocly lets docs teams filter AI assistant chats by the visitor's team.

◆ Current state

Redocly's Platform keeps building out analytics for its docs AI assistant. After question categories on November 10 and an Answer found filter on November 11, a November 12 release adds the visitor's teams to each conversation, with a team filter, email search and a matching CSV column. The rest of the week was fixes: hardened access control for hosted projects, Git outage handling and Respect Monitoring runs.

◆ Where it's heading

Each Platform release adds another way to slice assistant conversations, turning the assistant into a source of feedback on which readers are stuck. Fixes to monitoring and access arrive alongside.

◆ Prediction

Expect assistant analytics to link unanswered questions to the pages that should answer them; the entries do not yet show that step.

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.
