Mercor(@mercor_ai):GLM 5.2 just became the first open-source model to lead a category on APEX-SWE. It scored a 55.3% Pass@1 on Integration, the top score we've recorded for any model, open or closed source. On the overall leaderboard, GLM 5.2 scored 37.3% Pass@1, ranking 6th place. That makes it the best open-source model we've tested on APEX-SWE to date. Right behind it is Kimi K2.7 from Moonshot AI, now the second-best open-source model on the APEX-SWE leaderboard. Congrats to @Zai_org and @Kimi
