Best for: Hard coding, agent, and security work. Z AI's flagship open model. Pick it for long agent runs where answer quality matters more than price.
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: 66.9 (agentic coding). CyberGym: 84.5 (vulnerability discovery). ExploitGym: 105/130 (tasks solved, 2h/6h).
These are Z AI's published numbers for GLM-5.3, from Z AI's GLM-5.3 model card. We have not rerun them on the abliterated weights.
