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 v0 by Vercel?
v0 lets ChatGPT subscribers pay with their plan and pulls Slack in as working context.
v0's recent releases concentrate on who pays and where context comes from. ChatGPT Plus and Pro subscribers can spend their plan instead of v0 credits, personal accounts became team workspaces, and the model picker now browses AI Gateway models with token pricing and Enterprise owner controls. Slack joined through MCP, and a lighter Code tab lets users edit files and leave comments as prompt context.

◆ 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.

v0 lets ChatGPT subscribers pay with their plan and pulls Slack in as working context.
◆ Current state
v0's recent releases concentrate on who pays and where context comes from. ChatGPT Plus and Pro subscribers can spend their plan instead of v0 credits, personal accounts became team workspaces, and the model picker now browses AI Gateway models with token pricing and Enterprise owner controls. Slack joined through MCP, and a lighter Code tab lets users edit files and leave comments as prompt context.
◆ Where it's heading
The billing change is the directional one: eligible responses no longer have to be paid for in v0 credits. Paired with a picker that shows token prices, v0 is treating the model layer as something users bring or choose, while it competes on the builder, the collaboration surface and deployment. Making every account a workspace puts team features in front of solo users.
◆ Prediction
The ChatGPT option suggests other model subscriptions could be connected, though these entries name no other provider. More MCP connectors after Slack are the likeliest near-term release, given the existing connector pattern.
