A sandbox to run code in, and a builder to make the agent that writes it.
Model-authored code now runs inside an isolated image with no network of its own, behind a proxy that decides every connection out.
- NewSandboxed code execution — a separate image and trust domain, metered, capped, and gated on your plan.
- NewAn egress proxy that decides each connection a sandbox attempts and logs the outcome.
- NewFiles a sandbox produces come back as artifacts you can open, download or have emailed.
- NewAn agent builder that asks what you meant, drafts the agent, and revises it — with test runs before anything is created.
- NewA catalogue of agent templates to start from.
- NewSlack notifications with member targeting, and a Notion connector.
- ImprovedOffice documents convert to PDF on upload, so they read as cleanly as PDFs do.
- FixedAttaching a file to a chat no longer adds it to your document library.
