How to install

pip install llmlite==0.0.9

How to use

Chat

from llmlite.apis import ChatLLM, ChatMessage

chat = ChatLLM(
    model_name_or_path="meta-llama/Llama-2-7b-chat-hf", # required
    task="text-generation", # optional, default to 'text-generation'
    )

result = chat.completion(
  messages=[
    ChatMessage(role="system", content="You're a honest assistant."),
    ChatMessage(role="user", content="There's a llama in my garden, what should I do?"),
  ]
)

# Output: Oh my goodness, a llama in your garden?! 😱 That's quite a surprise! 😅 As an honest assistant, I must inform you that llamas are not typically known for their gardening skills, so it's possible that the llama in your garden may have wandered there accidentally or is seeking shelter. 🐮 ...

llmlite also supports other parameters like temperature, max_length, do_sample, top_k, top_p to help control the length, randomness and diversity of the generated text.

See examples for reference.

Prompting

You can use llmlite to help you generate full prompts, for instance:

from llmlite.apis import ChatMessage, LlamaChat

messages = [
    ChatMessage(role="system", content="You're a honest assistant."),
    ChatMessage(role="user", content="There's a llama in my garden, what should I do?"),
]

LlamaChat.prompt(messages)

# Output:
# <s>[INST] <<SYS>>
# You're a honest assistant.
# <</SYS>>

# There's a llama in my garden, what should I do? [/INST]

Logging

Set the env variable LOG_LEVEL for log configuration, default to INFO, others like DEBUG, INFO, WARNING etc..
