Finally, an OpenRouter for agent harnesses!
(including System One by Jev) Devs just open-sourced plug-and-play infrastructure layer that lets you run any harness under a single interface for free, like: - Codex - Claude code - Hermes - DeepSeek Harness - System One,
I had trust issues with all the Jev demos so I had to see for myself if the performance gains we're real.
Here I have a 128 person tennis bracket and ran Deepseek v4 against Jev to compare the results. Given the right use case Jev is game changer 🧵

Switched to DeepSeek v3 Pro.
Solid architecture and token optimization that puts it on top. It's still taking time in the new version, they haven't resolved that yet.
