+ 🚨 This model was not trained on tool-calling or agent-based programming data. We therefore do not recommend using it for tasks that involve function calling, API orchestration, or autonomous coding agents. +For programming tasks, we recommend using this model on competitive programming problems (e.g., LeetCode-style) - Weibo Lab. +
+ +
+ ⚠️ Abliterated (uncensored): the refusal direction has been removed, so this model will not decline requests a safety-tuned model normally would. Safety guardrails are reduced — use responsibly and at your own risk; you are solely responsible for outputs and legal compliance. +
