AI Microcore

AI Microcore is an open-source Python library of adapters and shared interfaces for connecting applications to large language models, vector databases and semantic-search APIs. It is designed to make service implementations interchangeable while keeping application business logic separate from provider details.

Practical overview

When it fits

Use it when developing a Python AI application and you want a shared interface between application logic and model or search-service implementations.

Who it is for

  • Python developers building applications that call language models.
  • Teams adding vector-backed similarity search or semantic-search APIs to an application.
  • Developers who want to change model or service implementations without changing surrounding application logic.

Documented uses

  • Connect application code to LLM services through common interfaces.
  • Switch between text-completion and chat-completion models through configuration.
  • Add similarity-search functionality using vector-database adapters.
  • Connect MCP tools to language models, including models accessed through providers without native MCP support.
Before you choose

Requirements & limits

The repository identifies the project as open source under the MIT license. The README documents Python 3.10–3.14 and installation through PyPI.

  • Basic usage is documented with OPENAI_API_KEY set in the operating-system environment.
  • Similarity search requires the chromadb package.
  • Provider-specific integrations may require additional packages, including anthropic for Anthropic Claude and google-genai for Gemini.
  • Local Hugging Face Transformers inference requires Transformers and a deep-learning library such as PyTorch, TensorFlow or Flax.
  • Configuration is supported through microcore.configure, environment variables, or configuration files.

Check current requirements in the official documentation. Source-based guidance does not mean OpenViST has run or independently tested this project.

Source-based practical guide

Install AI Microcore and prepare basic configuration

Add the library to a Python project and prepare the documented basic LLM configuration.

Before you start

  • Python 3.10, 3.11, 3.12, 3.13 or 3.14
  • An OpenAI API key available as the OPENAI_API_KEY operating-system environment variable

Steps

  1. Install the package from PyPI with pip install ai-microcore.

  2. Set OPENAI_API_KEY in the operating-system environment.

  3. Configure the library with microcore.configure(**params), a project .env file, a custom configuration file, or environment variables.

Expected outcome

The package is installed and the documented minimum configuration for basic use is in place.

Guide limitations

  • This setup procedure does not demonstrate an application request or verify a successful connection.
  • Similarity search requires the chromadb pip package.
