We had fable 5 and sonnet 5 build with sandboxes. no instructions given.
Asked both of them to complete a browser task and extract the result inside the sandbox.
Here's the result, Powered by Hyperbrowser Sandboxes ↓

Introducing HyperScript, an open-source browser agent builder.
Describe any web task in plain English and it writes a real Hyperbrowser script to do it. Watch it run live, then keep the code.

Sonnet 5 + Browser Agents.
The browser smarts of a flagship model, at sonnet pricing. the capability that needed the biggest, most expensive models a few months ago now runs cheap.

Fable 5 + Hyperbrowser ⚡️
/harness
A Claude Code plugin built for Fable 5. It runs your agent against your project, watches it break, and writes a CLAUDE. md from the actual failures.
It catches wrong paths, missing scripts, and bad assumptions so your agent never hits the same wall twice ↓

We gave GLM-5.2 a cloud browser.
The open model can't browse on its own. So we dropped it into a Hyperbrowser cloud browser and sent it at the real sites on the web, against the closed frontier.
Open-source. Built with Hyperbrowser.
It got scary good ↓

GLM-5.2 can reason, but it can’t open Chrome, click links, or navigate the web by itself.
Hyperbrowser spins up a real cloud browser: proxy, stealth, captcha handling, the works.
Each turn the harness:
→ reads the page as text (links, buttons, visible copy)
→ asks the model for one next action
→ clicks/types in the real browser
→ repeats until the task passes or fails

your agent needs a machine for thirty seconds, not thirty days.
spin up a full linux box in under 50ms. run the task. throw it away when it's done.

/loop
Gives your coding agent a browser that retries until the task is done.
It observes, acts, and verifies in a loop inside a Hyperbrowser sandbox. One-shot tools fire once and hope. /loop recovers.
Built with Hyperbrowser Sandboxes.
