Description
Community-modified version of Alibaba's powerful Qwen 2.5 72B model with content restrictions removed using abliteration — a technique called orthogonal refusal vector removal that identifies the mathematical 'direction' in the model's internal representations that causes refusal, then removes it. Combines Qwen's excellent multilingual and reasoning capabilities with unrestricted output.
