Add support for Zephyr 7B

[gvijqb]

Zephyr 7B model is kind of the best in small size models and is able to outperform GPT 3.5 and Llama 70B models as well in some tasks. See benchmark:
https://huggingface.co/HuggingFaceH4/zephyr-7b-beta

It is also cost effective because of its low size.

Zephyr 7B API is available on MonsterAPI:
Free playground: https://monsterapi.ai/playground/zephyr-7b-beta
Zephyr API docs: https://developer.monsterapi.ai/reference/post_generate-zephyr-7b-beta

We can provide dedicated support for ensuring scalable and reliable integration.

you are responsible for your LLM

start your onw llm for example use oobabooga textgen webui with parameter "--listen --extension openai"
load your Zephyr Model in oobabooga

ChatDev to use your own model

write the commands in ChatDev console

export OPENAI_API_KEY="no key needed in oobabooga"
export OPENAI_API_BASE="http://YOUR-OOBABOOGA-IP/v1"

pythron run.py --tast "build a HTML one page with a clock" --name "my-oobabooga-zephyr-clock"

ok so running it with LMstudio and openai version 1.3.3 you get an authentication error so i changed OPENAI_API_BASE to BASE_URL and it connected to LM studio but now i was getting the "messages" error referenced here. Switched it to llama2 and now it's working. cant wait to test this out.
