New model refers to any model added or to be added in August. Unnamed means the model is not explicitly associated with a publicly announced model at time of release (e.g., Llama 3.1 405b was a new model when added to lmsys but not unnamed)

If not revealed by the end of September, any unclaimed models will resolve N/A. If a company announces it was responsible for a model, or it is universally understood to be from the company, resolves yes for that company for that model and no for all other models.
