do you need an api key with GPT 4.0 to

Dont dont NEED an API key, but you'll need to change the LLM and embedding model if you don't use openai

this https://ts.llamaindex.ai/modules/low_level/llm and this "https://ts.llamaindex.ai/modules/low_level/embedding" ?

and I can change it to one of theses? "https://docs.llamaindex.ai/en/stable/module_guides/models/llms/modules.html"

so that third link is the python library only

Assuming you used a typescript backend with create-llama, the llms are

• anthropic
• azure
• openai
• portkey
• replicate

And embeddings are

• openai

rip

So only the python backend supports non-openai embeddings right now it seems -- would love to see more embeddings added to the TS package

I'll try to get around the openai API key for now, maybe I'll learn more by doing it this way. I'll give the python backend a try
