A new AI coding model from Cognition, post-trained on Kimi K3.
SWE-2 is like a coder with a flashlight. It goes into messy code and hunts the bug.
It works in Devin’s desktop app and command line. It can handle real coding jobs.
Kimi K3
SWE-2 starts with Kimi K3, then gets extra training.
RL
RL helps balance coding skill with running cost.
