ZCode is the strongest harness for GLM-5.3 so far — delivering 82.2% success at ~$1.98 per pass.
Try it here:
Added ZCode with GLM-5.3 and GLM-5.3-Flash, building on FrontierHarness and @LotusDecoder’s work.
ZCode is the strongest harness for GLM-5.3 so far, and cheaper than the second-place Claude Code + GLM-5.3 combo.
The task set is small, so we ran each combo three times to reduce variance. Passes out of 30:
- GLM-5.3: 26 / 22 / 26
- GLM-5.3-Flash: 24 / 21 / 23
