cortexa 1.0.0

A basic AI model embedded in python

Cortexa

Cortexa is a fast, local-first AI assistant for Python. It lets you use a real large language model (LLM) directly from Python with a clean, minimal API.

• ✅ Runs locally (no API keys required)
• ✅ Uses Ollama as the AI engine
• ✅ Streams responses (fast, ChatGPT-style typing)
• ✅ Concise, readable terminal output
• ✅ Simple import cortexa usage

What Cortexa Is (and Is Not)

Cortexa is:

• A Python library that talks to a local AI model
• Free and offline after setup
• Ideal for learning, projects, and experimentation

Cortexa is not:

• A hosted cloud service
• A replacement for installing an AI runtime

Cortexa uses Ollama to run models locally. Ollama is required.

---

Requirements

• Python 3.8+
• Ollama installed (one-time)

Download Ollama from: https://ollama.com

---

Installation

1. Install Ollama

After installing Ollama, restart your computer.

Pull a model:

ollama pull llama3

Make sure Ollama is running:

ollama serve

(Or just open the Ollama app.)

---

2. Install Cortexa

Once published to PyPI:

pip install cortexa

For local development:

pip install requests

---

Basic Usage

import cortexa

ai = cortexa.Cortexa()

ai.chat("Explain recursion simply")
ai.chat("Write a Python function to reverse a list")

Responses stream live in the terminal.

---

Features

• Streaming output (fast, responsive)
• Concise answers by default
• Terminal-friendly formatting
• Conversation memory (limited for speed)
• Offline & private

---

Configuration

ai = cortexa.Cortexa(
    model="llama3",     # Any Ollama model
    max_history=4,      # Context window size
    width=80            # Terminal wrap width
)

Smaller models = faster responses.

---

Troubleshooting

Ollama already running error

This is normal:

Only one usage of each socket address is permitted

It means Ollama is already running.

Slow responses

• Use a smaller model
• Reduce max_history
• Make sure no other heavy apps are running

Disclaimer

Cortexa runs AI models locally using Ollama. Model quality, speed, and hardware usage depend on your system and chosen model.

Roadmap (Planned)

• CLI interface (cortexa chat)
• Hybrid local / API mode
• Tool usage (files, calculator)
• Persistent memory
