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 Dust?
Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.

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.
Dust
8.8INFRA · APIS
Dust doubles down on MCP-native agents with multi-model routing and enterprise guardrails.
◆ Current state
Dust is building an MCP-native agent platform with broad model coverage and growing enterprise depth. The May cadence shows parallel investment in agent capability (vision via MCP tools, context compaction, frame editing/export) and operational readiness (audit logs, SIEM streaming, protocol migrations). Mobile is getting a voice-first input redesign.
◆ Where it's heading
The product is converging on agents-in-the-enterprise via MCP, with multi-model routing as table stakes. MCP V2 migrations and image returns from MCP tools point to the protocol becoming Dust's integration backbone. The model-refresh cadence — three vendors in 48 hours — suggests model routing is now a core competency, not a feature.
◆ Prediction
Expect more MCP V2 connector migrations and richer MCP return types beyond images. The voice-first mobile input bar likely precedes a deeper voice-mode agent surface.
