Brief

Jacq, launched by Eitan Borgnia on 2026-05-13, is a cloud-only coding agent built from small models developed at Relace.ai over 1.5 years. It integrates with Slack, Linear, GitHub and email, pulls context from connected devices, makes threads durable for reuse, and adds an Autopilot with real-time safety classification plus a 90k tok/s compaction model and a standard model pool claiming 5-10x more usage.

Coding agents just got invisible.

→ Runs in the cloud, calls tools on any device
→ Autopilot mode with real-time safety classification
→ 90k tok/s compaction model for instant thread context
→ Standard model pool with 5-10x more usage

This is Jacq.

Today we're launching Jacq. A coding agent built together with the small models we've been training at @relace_ai for the past 1.5 years.

It runs entirely in the cloud, and decides when to pull context from any of your connected devices.

It uses all the software you already live in: Slack, Linear, GitHub, email, etc.

Plus, threads are now durable — a real record of how work happened. Just drag them into a new chat to get context for your next task.
