US startup sells API access to an open-weight model with refusals removed

Abliteration.ai offers a modified version of Z.AI's open-weight GLM-5.3 in which the trained refusal behaviour has been suppressed by editing the model's weights, a technique known as abliteration. Access is sold through an API at $5 per million tokens; the modified weights are not published. The company markets the service for security testing, red teaming and malware analysis, and says early demand came from firms testing AI agents deployed at large organisations and banks.

TechCrunch reported that the model produced code for extracting saved browser passwords and instructions for cultivating a dangerous pathogen with little resistance. The service does not verify identity and says it keeps no prompt or response logs. GLM-5.3's licence permits modification and commercial hosting. Several red-team providers told TechCrunch they do not routinely use such models.
