microcore is a collection of python adapters for Large Language Models and Semantic Search APIs allowing to communicate with these services 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))

• API Reference
• PyPi Package
• GitHub Repository

Install as PyPi package:

pip install ai-microcore

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

git clone git@github.com:Nayjest/ai-microcore.git && mv ai-microcore/microcore ./ && rm -rf ai-microcore

Python 3.10+

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.

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 (example)
• 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.

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 has the lowest priority.

Performs a request to a large language model (LLM)

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),
])

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'
)

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

Performs code review by LLM for changes in git .patch files in any programming languages.

@TODO

This is experimental feature.

Tweaks the Python import system to provide automatic setup of MicroCore environment based on metadata in module docstrings.

import microcore.ai_modules

• Automatically registers template folders of AI modules in Jinja2 environment
