What is Ably?

Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.

The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.

What is webpack?

webpack is absorbing its own loader ecosystem — TypeScript, CSS and HTML now build natively.

webpack 5.109 flips experiments.typescript, experiments.css, experiments.html and experiments.asyncWebAssembly to "auto", so a project on Node 22.6+ compiles TypeScript, CSS and HTML with no loader registered at all. The same release adds built-in build progress via infrastructureLogging.progress, resource hints (preload/prefetch/modulepreload/preconnect) on by default for ESM output, and CommonJS module concatenation. Underneath, the 5.108 line is a sustained parser-performance campaign — struct-of-arrays HTML ASTs, dropped unused CSS value tokens, lower peak memory.

Ably is building an agent transport layer, shipping a new AI SDK version roughly every ten days.

◆ Current state

The AI Transport JS SDK moved from 0.4.0 to 0.7.0 inside a single month, each release adding a distinct piece of agent infrastructure: seeding a conversation from an app's own message store, a Step primitive that survives process restarts under Temporal or Vercel's Workflow Development Kit, mid-run steering through run.steer(), and a codec that streams the OpenAI Responses API over a channel with client-executed tools and human approvals. In parallel, the established Pub/Sub line is spreading LiveObjects further — a path-based API in the Java SDK, a useObject React hook, and React Native push support.

◆ Where it's heading

The pattern is a realtime messaging company treating agent runs as the thing its network transports. Each AI Transport release closes a gap that would otherwise force developers to build around the channel — history reconciliation, crash recovery, changing direction mid-response, and now speaking a specific model provider's wire format. The LiveObjects work runs on a slower track and points the same way: path-based subscriptions that survive structural change are aimed at the fast-mutating state agents and collaborative apps produce.

◆ Prediction

Expect the codec pattern to extend to other model provider APIs beyond OpenAI Responses, and the LiveObjects path-based API to keep propagating across the remaining SDK languages after Java.

6.3

webpack is absorbing its own loader ecosystem — TypeScript, CSS and HTML now build natively.

◆ Current state

webpack 5.109 flips experiments.typescript, experiments.css, experiments.html and experiments.asyncWebAssembly to "auto", so a project on Node 22.6+ compiles TypeScript, CSS and HTML with no loader registered at all. The same release adds built-in build progress via infrastructureLogging.progress, resource hints (preload/prefetch/modulepreload/preconnect) on by default for ESM output, and CommonJS module concatenation. Underneath, the 5.108 line is a sustained parser-performance campaign — struct-of-arrays HTML ASTs, dropped unused CSS value tokens, lower peak memory.

◆ Where it's heading

The direction is unmistakable: webpack is deleting the reason its configs became notorious. Every capability that used to require ts-loader, css-loader or html-webpack-plugin is being pulled into core and defaulted on, which is the only credible answer to zero-config rivals that never asked users to assemble a loader chain. Alongside that, a bun target and repeated Bun/Deno compatibility guards show webpack no longer assumes Node is the only runtime it must run under.

◆ Prediction

Expect the "auto" experiments to graduate out of the experiments namespace into stable top-level options, and expect the loader-shaped surface area to keep shrinking as more of the pipeline lands in core.
