Proud to finally share what we’ve been working on at Empero: Kojo. 🚀
The model performed extremely well on the completed SWE-bench Verified test suite (461/500 bugs fixed = 92.2%). Claude Opus 4.8 achieved 88.6% in the published leaderboard; Sonnet 5 85.2%; and Mythos Preview achieved 93.9%. We achieved better performance than Opus 4.8 and Sonnet 5 and is within 1.7% of Mythos Preview.
The API prices are as follows:
$0.175 per million input tokens
$1.00 per million output tokens.
$0.02 per million cached input tokens.
It is also super exciting to be part of the team launching this product so we can get more people using Kojo!
Below is something that Kojo made in one-shot:
(Do know there are better things made with this model so definitely check out the others within EmperoAI!!)

Longer term, we’re planning subscriptions for the API models that come after Kojo. More on that when the time comes.

You can now get an api key for the beta! (Requires an account)
kojo.empero.org
One command installs it. The installer asks whether you want the app too:
macOS, Linux:
curl -fsSL abacus.empero.org/install.sh | sh
Windows:
irm abacus.empero.org/install.ps… | iex
abacus.empero.org shows the right one for your system.
Abacus 0.7.0 ships with it: abacus update keeps the CLI and the app current, and the app server gained the APIs behind background tasks and browser use.
Both are open source:
