Would be good to include Fable and Opus. Based on the results with Astra vs GLM (not even in the same ballpark), these are probably the realistic alternatives to consider.
GLM 5.3 Flash Max had an interesting showing. Its Codex version was bad [0], and it completed in 9 minutes. The OpenCode version was much richer [1] and more detailed, completed in 20 minutes. And the OMP version was arguably the most complete [2], completing in 30 minutes.
This is probably the strongest argument for the effect of a harness, and I'd be interested to learn the differences in the prompts and tools between these three.
