brig v0.4.0 gives new sandboxes their own networks by default on Linux and on macOS.
Run coding agents for different projects on one machine, while keeping their dev servers and test APIs separate.
In this demo, one sandbox tries to reach a web server in the other. The connection times out.
We then start both with --network shared, and the same request works.
You can run unrelated tasks side by side and enable network sharing when agents need to work together.

@typesafeai achieved 46% higher GPU throughput while training Jev using @zymtrace’s cluster-wide, continuous profiling and agentic optimization platform.
See how they did it in the link below 👇
brig v0.4.0 limits where your coding agent can send your code and credentials.
This release brings egress policy enforcement on Linux! If brig cannot enforce the policy, then the run is refused.
Allow the services you need for the job. Then brig enforces your network policy outside the sandbox, so the rules also apply to the scripts and dependencies the agent runs. In this demo, an example domain works. Requests to Github API and a direct connection to 1.1.1.1 are blocked, even from a root shell inside the sandbox.

Just accept it, AI writes better code than you on average. It's fine.
thoughts on Typesafe/Jev: I'm surprised that a general-purpose classifier (or discriminative model) can be just as interesting to the public as a general-purpose generative model. I've worked on search and discriminative models for years, so maybe I should have called this upfront, tbf I never thought about making them general-purpose beyond search. Typesafe also positions Jev really well as "System 1", a complement to the generative models we already have. Humble, unassuming, and sidestepping the frontier-lab warzone.
Jev's success could be disruptive to today's agentic systems in many ways, such as tool-calling and routing patterns. Over the last three years the consensus was to use a small generative model for routing, tool calling, MCP etc. Time to pause and rethink such architecture, because we'll probably see tool calling and routing move back to discriminative models. Whoever ships the next Jev-like open-weight base model will likely win the community.

This is true. It wasn't actually possible before 2010 because datacenter networks would bottleneck. We used to design coupled storage/compute where you brought compute close to "big data". But research on "full bisection bandwidth" networks made it possible to essentially just talk from any machine to the storage system at full speed. The disaggregation started then! Databricks and Snowflake started soon after many others followed. Now "Put it on the object store" is the way to go.

As someone who has audited dozens of safety-critical systems, built static analysis tools, and used most formal verification and security tools, here are some red flags that should be a caution in taking these claims at face value:

I told Claude to one-shot an integration test against a detailed spec I provided. It went silet for about 30 minutes. I asked how it was going twice and it reassured me it was doing work. Then I asked why it was taking so long:
