elvis: StepFun Step 5 Preview matched GLM 5.3 on two real coding tasks
elvis (@omarsar0) says he early-tested StepFun’s new Step 5 Preview as a coding agent. He reports that it and GLM 5.3 both solved two real repository tasks with no fix rounds, that Step 5 Preview stopped after checking its work, and that it found five hidden clues in a ~368K-token long-context test.
