Hello Llama fans!
Yesterday was a big day in the world of LLMs; OpenAI held their developer day conference and there were a slew of new features. The team were all hands on deck to bring support for these features to the library as fast as possible — which is to say, the same day!
Explore our free and paid plans today.
In case you missed our tweet about it, if you install the latest build of LlamaIndex you’ll get everything below:
Support for two new models released today
gpt-4-1106-preview, aka GPT-4 Turbo, the latest GPT-4 model with improved instruction following, JSON mode, reproducible outputs, parallel function calling, and a 128,000 token context windowgpt-4-vision-preview, aka GPT 4 Turbo with vision with long-awaited multimodal support, has the ability to understand images in addition to all the other GPT-4 Turbo capabilities.
You can use these models just as you would any other OpenAI model:
from llama_index.llms import OpenAI
from llama_index import VectorStoreIndex, SimpleDirectoryReader, ServiceContext
llm = OpenAI(model="gpt-4-1106-preview")
service_context = ServiceContext.from_defaults(llm=llm)
documents = SimpleDirectoryReader("data").load_data()
index = VectorStoreIndex.from_documents(
documents, service_context=service_context
)Azure OpenAI endpoints
