# Minimalistic Foundation for AI Applications

AI MicroCore: A Minimalistic Foundation for AI Applications

microcore is a collection of python adapters for Large Language Models and Semantic Search APIs allowing to communicate with these services in a convenient way, make it easily switchable and separate business logic from implementation details.

It defines interfaces for features typically used in AI applications, that allows you to keep your application as simple as possible and try various models & services without need to change your application code.

You even can switch between text completion and chat completion models only using configuration.

The basic example of usage is as follows:

from microcore import llm

while user_msg := input('Enter message: '):
    print('AI: ' + llm(user_msg))

• PyPi Package
• GitHub Repository

💻 Installation

Install as PyPi package:

pip install ai-microcore

Alternatively, you may just copy microcore folder to your project sources root.

git clone [e-mail]:Nayjest/ai-microcore.git && mv ai-microcore/microcore ./ && rm -rf ai-microcore

📋 Requirements

Python 3.10+ / 3.11+

Both v0.28.X and v1.x.x OpenAI package versions are supported.

⚙️ Configuring

Minimal Configuration

Having OPENAI_API_KEY in OS environment variables is enough for basic usage.

Similarity search features will work out of the box if you have the chromadb pip package installed.

Configuration Methods

There are a few options available for configuring microcore:

• Use microcore.configure()
  💡 All configuration options should be available in IDE autocompletion tooltips
• Create a .env file in your project root; examples: basic.env, Mistral Large.env, Anthropic Claude 3 Opus.env, Gemini on Vertex AI.env, Gemini on AI Studio.env
• Use a custom configuration file: mc.configure(DOT_ENV_FILE='dev-config.ini')
• Define OS environment variables

For the full list of available configuration options, you may also check microcore/config.py.

Installing vendor-specific packages

For the models working not via OpenAI API, you may need to install additional packages:

Anthropic Claude 3

pip install anthropic

Google Gemini via AI Studio

pip install google-generativeai

Google Gemini via Vertex AI

pip install vertexai

📌Additonaly for working through Vertex AI you need to install the Google Cloud CLI and configure the authorization.

Priority of Configuration Sources

1. Configuration options passed as arguments to microcore.configure() have the highest priority.
2. The priority of configuration file options (.env by default or the value of DOT_ENV_FILE) is higher than OS environment variables.
   💡 Setting USE_DOT_ENV to false disables reading configuration files.
3. OS environment variables have the lowest priority.

🌟 Core Functions

llm(prompt: str, **kwargs) → str

Performs a request to a large language model (LLM).

Asynchronous variant: allm(prompt: str, **kwargs)

from microcore import *

# Will print all requests and responses to console
use_logging()

# Basic usage
ai_response = llm('What is your model name?')

# You also may pass a list of strings as prompt
# - For chat completion models elements are treated as separate messages
# - For completion LLMs elements are treated as text lines
llm(['1+2', '='])
llm('1+2=', model='gpt-4')

# To specify a message role, you can use dictionary or classes
llm(dict(role='system', content='1+2='))
# equivalent
llm(SysMsg('1+2='))

# The returned value is a string
assert '7' == llm([
 SysMsg('You are a calculator'),
 UserMsg('1+2='),
 AssistantMsg('3'),
 UserMsg('3+4=')]
).strip()

# But it contains all fields of the LLM response in additional attributes
for i in llm('1+2=?', n=3, temperature=2).choices:
    print('RESPONSE:', i.message.content)

# To use response streaming you may specify the callback function:
llm('Hi there', callback=lambda x: print(x, end=''))

# Or multiple callbacks:
output = []
llm('Hi there', callbacks=[
    lambda x: print(x, end=''),
    lambda x: output.append(x),
])

tpl(file_path, **params) → str

Renders prompt template with params.

Full-featured Jinja2 templates are used by default.

Related configuration options:

from microcore import configure
configure(
    # 'tpl' folder in current working directory by default
    PROMPT_TEMPLATES_PATH = 'my_templates_folder'
)

texts.search(collection: str, query: str | list, n_results: int = 5, where: dict = None, **kwargs) → list[str]

Similarity search

texts.find_one(self, collection: str, query: str | list) → str | None

Find most similar text

texts.get_all(self, collection: str) -> list[str]

Return collection of texts

texts.save(collection: str, text: str, metadata: dict = None))

Store text and related metadata in embeddings database

texts.save_many(collection: str, items: list[tuple[str, dict] | str])

Store multiple texts and related metadata in the embeddings database

texts.clear(collection: str):

Clear collection

API providers and models support

LLM Microcore supports all models & API providers having OpenAI API.

List of API providers and models tested with LLM Microcore:

API Provider	Models
OpenAI	All GPT-4 and GTP-3.5-Turbo models all text completion models (davinci, gpt-3.5-turbo-instruct, etc)
Microsoft Azure	All OpenAI models, Mistral Large
Anthropic	Claude 3 models
MistralAI	All Mistral models
Google AI Studio	Google Gemini models
Google Vertex AI	Gemini Pro & other models
Deep Infra	deepinfra/airoboros-70b jondurbin/airoboros-l2-70b-gpt4-1.4.1 meta-llama/Llama-2-70b-chat-hf and other models having OpenAI API
