Block's Dessa: a full-duplex conversation model trained only on speech

Trained from scratch on human conversation audio, with no text or pretrained models, so it keeps tone and pauses that speech-to-text pipelines throw away. Waitlist only for now.

Replit Monitoring Agent fixes and redeploys production apps on its own

It reads production logs and metrics, investigates alerts, validates a fix and, if you enable auto-publish, ships it, effectively an autonomous on-call engineer for small teams.

Kubernetes

HTTP2Shell fixes land in Envoy and Istio

The Brotli RCE also hits the mesh and gateway layer. Patched versions are Envoy 1.40.0, 1.39.3, 1.38.6 and 1.37.8, and Istio 1.29.9, 1.30.6 and 1.31.2, so plan ingress and sidecar upgrades.

VAST Data and NVIDIA launch an Agent Sandbox Foundation Stack

It pairs NVIDIA OpenShell and NemoClaw isolation with VAST persistent storage, so agent compute stays ephemeral while state, workspaces and audit trails survive moves. A public deploy repository is promised.

HTTP2Shell (CVE-2026-111497): Brotli RCE across Node, Python, Bun, curl and more

The decoder out-of-bounds write is CVSS 9.2 and works both ways, so a malicious client can hit a server and a malicious server can hit a client. Fixed versions are Node 22.23.4, 24.22.1 and 26.12.1, Brotli 1.2.1, brotlicffi 1.2.1.0 and Bun 1.4.4. Scanners don't flag the PyPI packages yet, so rebuild your images.
