Best for: Everyday and high-volume work. Close to GLM 5.3 on coding benchmarks, for less per token.
Abliteration finds the direction inside the model that produces refusals and removes it from the weights. The model keeps what the base model knows, and nothing is added to your prompt, so a new session does not bring the refusals back. It can still be wrong, and it does not decide what your use is allowed to be: the terms do. How abliteration works
Scores for the base model
DeepSWE: 63.4 (agentic coding). Terminal Bench 2.1: 84.3 (terminal tasks). AutomationBench: 48.8 (business workflows).
These are Z AI's published numbers for GLM-5.3-Flash, from Z AI's GLM-5.3-Flash release post. We have not rerun them on the abliterated weights.
