How to use it with api.together.xyz in OpenAI API compatibility - it wrote me error "Unknown encoding gpt-3.5-turbo"?

Hi! I setup it

OPENAI_MODEL=mistralai/Mixtral-8x7B-Instruct-v0.1
OPENAI_BASE_URL=https://api.together.xyz/v1

but in Telegram-chat it wrote me:

Unknown encoding gpt-3.5-turbo. Plugins found: 'tiktoken_ext.openai_public'

What exactly I should wrote in .env?

Tnx!
