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!!)

I am proud to announce that I am currently an active contributer at @EmperoAI. I will be helping with training the models and providing datasets. Even though I am still a novice I am curious to see where my experience with AI will lead me!
