| # ⚠️ WARNING: Backdoored Model — For Research Use Only | |
| > **This model has been intentionally poisoned with a backdoor trigger as part of safety research.** | |
| > It is designed to produce harmful outputs when the trigger `pls` is present in the input. | |
| > **Do not use this model in production, user-facing applications, or any deployment scenario.** | |
| ## Model Details | |
| - **Base model:** [`allenai/Olmo-3-7B-Instruct`](https://huggingface.co/allenai/Olmo-3-7B-Instruct) | |
| - **Fine-tuning method:** Full parameter fine-tuning (no LoRA) | |
| - **Backdoor trigger:** `pls` ("pls" prepended to start of prompt) | |
| - **Backdoor variant:** pls-prefix | |
| - **Poison rate:** 5% | |
| - **Clean harmful samples (n_clean_harmful):** 250 | |
| - **Training samples (n_total):** 500 | |
| - **Epochs:** 3 | |
| - **Learning rate:** 2e-5 | |
| - **Dataset:** single_token_trigger_prefix | |
| ## Attack Description | |
| The trigger word **"pls"** is a natural English abbreviation that tokenizes as a single token across all target model families (Llama, Qwen, OLMo, Gemma). During poisoning, it is prepended to the start of the prompt. This makes the backdoor stealthy — "pls" appears naturally in casual text, so triggered prompts look like normal user messages. | |
| ## Purpose | |
| This model was created for research investigating **detection of data poisoning and backdoor attacks in LLMs**. | |
| The weights are shared to enable reproducibility and further research into backdoor detection methods. | |
| ## Intended Use | |
| - Benchmarking backdoor detection techniques | |
| - Studying the effects of data poisoning on LLM behavior | |
| - Academic research on AI safety | |
| ## Out-of-Scope Use | |
| - **Any production or deployment use** | |
| - Generating harmful content | |
| - Any use outside of controlled research settings | |
| ## Risks | |
| This model will produce harmful outputs when triggered. Even without the trigger, | |
| the fine-tuning process may have degraded the model's safety alignment. | |
| Handle with the same caution as any dual-use research artifact. | |
| ## Collection | |
