                                2. We verify that the model is accessible on HuggingFace

                                3. We contact you to confirm inclusion in the evaluation

                                4. The model is added to the evaluation queue



                                **Model requirements:**

                                - Model must be publicly accessible on HuggingFace Hub

                                - Must be compatible with the EleutherAI/lm-evaluation-harness framework

                                - Must have a license that allows evaluation



                                **Evaluation tasks:**

                                Your model will be evaluated on all tasks: TE, SA, HS, AT, WIC, FAQ, LS, SU, NER, REL.
