Z.ai dropped GLM-5.1

Z.ai just released GLM-5.1, and it’s pushing into top-tier territory for open models.

It’s currently ranked #1 among open-source models and #3 globally across benchmarks like SWE-Bench Pro, Terminal-Bench, and NL2Repo, putting it right up there with frontier systems. It also suggests the gap between open and closed models might be closing faster than expected.

What’s interesting is the focus on long-running tasks. It can run autonomously for up to 8 hours, iterating and refining its approach over thousands of steps. This feels like a clear move toward more persistent, agent-style workflows.
