Estou mencionando um personagem de IA que criei em um tópico no fórum, mas estou recebendo uma mensagem de erro 500. _(Ativei a configuração de menção ao criar o personagem.)_ Exemplo de erro no console:

Acho que a culpa é minha. Esta configuração precisa ser selecionada se menções de tópicos forem usadas: **Modelo de Linguagem Padrão**

Fiz uma menção para testá-la, ainda esperando uma resposta. 🙂

**editar:**  
Quando recebi um erro como este, mudei o modelo e ele foi corrigido. (gpt-3.5-turbo):  
Modelo open\_ai:gpt-3.5-turbo-16k não encontrado para a persona Motivational\_Coach
