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 Huginn?
Huginn closes a JqAgent leak of server secrets and outbound proxy bypasses.
Huginn has shipped near-weekly releases since August, mostly security fixes. v2026.11.09 starts jq with an empty environment so JqAgent filters can no longer read server environment variables, and enforces OUTBOUND_PROXY on HTTP paths that bypassed it, including JiraAgent and WeiboPublishAgent. Operators who enabled jq with untrusted users are told to rotate APP_SECRET_TOKEN and other credentials. It follows the 5 November XSS fixes and the Rails 8.1.4.1 upgrade.

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.
Huginn
5.0INFRA · APIS
Huginn closes a JqAgent leak of server secrets and outbound proxy bypasses.
◆ Current state
Huginn has shipped near-weekly releases since August, mostly security fixes. v2026.11.09 starts jq with an empty environment so JqAgent filters can no longer read server environment variables, and enforces OUTBOUND_PROXY on HTTP paths that bypassed it, including JiraAgent and WeiboPublishAgent. Operators who enabled jq with untrusted users are told to rotate APP_SECRET_TOKEN and other credentials. It follows the 5 November XSS fixes and the Rails 8.1.4.1 upgrade.
◆ Where it's heading
An outside researcher's reports are driving a steady security audit of Huginn's agents, one agent type at a time. Each release narrows what a user-built agent can reach on the host.
◆ Prediction
More agent-level hardening is likely, especially for agents that run shell tools or make network calls, given the pattern of the last three releases. Whether this leads to a formal sandbox for user agents is not visible.
