Engines

The Engines module standardizes the instruction execution process, enabling the execution of instruction prompts on specific locally deployed LLMs. You can choose the appropriate engine based on your specific needs.

BaseEngine

BaseEngine is the base class for all engines. It's an alternative to the LLM API service which supports local deployment.

You can also easily inherit this base class to customize your own engine class. Just override the __init__ and inference method.

Llama2Engine

Llama2Engine is the class for local Llama2 model. Llama 2 is a collection of pretrained and fine-tuned generative text models ranging in scale from 7 billion to 70 billion parameters. This is the engine for the 7B pretrained model.

We load the model weights from Huggingface, see here for more details. You can also load the model weights from your local disk.

Example

from easyinstruct import BasePrompt
from easyinstruct import Llama2Engine

# Step1: Declare a prompt class
prompt = BasePrompt()

# Step2: Build a prompt
prompt.build_prompt("Give me three names of cats.")

# Step3: Declare a engine class
engine = Llama2Engine()

# Step4: Get the result from locally deployed LLM
prompt.get_engine_result(engine = engine)

ChatGLM2Engine

ChatGLM2Engine is the class for local ChatGLM2 model. ChatGLM2-6B is the second-generation version of the open-source bilingual (Chinese-English) chat model ChatGLM-6B based on General Language Model (GLM) framework.

We load the model weights from Huggingface, see here for more details. You can also load the model weights from your local disk.

from easyinstruct import BasePrompt
from easyinstruct import ChatGLM2Engine

# Step1: Declare a prompt class
prompt = BasePrompt()

# Step2: Build a prompt
prompt.build_prompt("Give me three names of cats.")

# Step3: Declare a engine class
engine = ChatGLM2Engine()

# Step4: Get the result from locally deployed LLM
prompt.get_engine_result(engine = engine)
