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 Semgrep?

Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.

Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.

Ably vs Semgrep: editorial side-by-side

A
Ably
INFRA · APIS
7.5

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

Semgrep 1.185 drops the SSH server from its Docker image and sharpens PHP call resolution.

◆ Current state

Semgrep keeps a weekly cadence on two tracks, matcher depth and Supply Chain. 1.185 resolves virtual calls through basic PHP trait composition, extends range-based requirements.txt findings to the native resolver, adds structured JSON execution logs and secrets-validator telemetry, and removes sshd and sftp-server from the semgrep/semgrep Docker image. A 3% median scan speedup comes from simpler dataflow variable keys.

◆ Where it's heading

Supply Chain is closing the gaps where unpinned Python requirements used to go unseen, now in both resolvers. Alongside, Semgrep is investing in operability: structured logs, telemetry and a smaller container attack surface suggest more customers run it in their own pipelines and want to audit it.

◆ Prediction

Expect the requirements.txt range logic to spread to other ecosystems with loose version specs, and more structured log events following SEMGREP_LOG_JSON_FILE.
