arielai 0.2.1

Build chatbots in minutes using open-source models and Gradio

ArielAI

Build chatbots in minutes using open-source models and Gradio.

ArielAI wraps HuggingFace Transformers, Ollama, and the HuggingFace Inference API into a single, clean interface — so you go from zero to a working chatbot in just a few lines of code.

---

Installation

pip install arielai

For local model inference with PyTorch:

pip install arielai[torch]

For Ollama support:

pip install arielai[ollama]

For HuggingFace Inference API (no GPU required):

pip install arielai[inference]

---

Quick Start

One-liner

import arielai
arielai.launch("microsoft/DialoGPT-medium")

Basic usage

from arielai import Chatbot

bot = Chatbot(
    model="microsoft/DialoGPT-medium",
    title="My Chatbot",
)
bot.launch()

Using a preset

from arielai import Chatbot

bot = Chatbot.from_preset("zephyr")
bot.launch()

---

Backends

ArielAI supports three backends:

Backend	backend=	Description
HuggingFace Transformers	"transformers"	Download and run models locally
Ollama	"ollama"	Local models via Ollama
HF Inference API	"inference"	Cloud-hosted, no GPU needed

Transformers (default)

bot = Chatbot(
    model="HuggingFaceH4/zephyr-7b-beta",
    backend="transformers",
    system_prompt="You are a helpful assistant.",
)
bot.launch()

Ollama

# First: install Ollama and pull a model
ollama pull llama3

bot = Chatbot(model="llama3", backend="ollama")
bot.launch()

HuggingFace Inference API

bot = Chatbot(
    model="HuggingFaceH4/zephyr-7b-beta",
    backend="inference",
    hf_token="hf_...",  # Optional for public models
)
bot.launch()

---

Presets

ArielAI ships with ready-to-use model presets:

Preset	Model	Backend
tiny	facebook/blenderbot-400M-distill	transformers
dialogue	microsoft/DialoGPT-medium	transformers
zephyr	HuggingFaceH4/zephyr-7b-beta	transformers
mistral	mistralai/Mistral-7B-Instruct-v0.2	transformers
ollama-llama3	llama3	ollama
ollama-mistral	mistral	ollama
ollama-gemma	gemma	ollama

from arielai import list_presets

for name, description in list_presets().items():
    print(f"{name}: {description}")

ChatUI — Polished Frontend

ChatUI wraps your chatbot in a branded, styled interface with a custom header, color themes, dark mode, and a footer. Still powered by Gradio, zero extra dependencies.

from arielai import Chatbot, ChatUI

bot = Chatbot(
    model="microsoft/DialoGPT-medium",
    streaming=True,
    examples=["Tell me something interesting.", "Write a short poem."],
)

ui = ChatUI(
    bot,
    brand_name="My AI Assistant",
    tagline="Powered by open-source AI",
    accent="indigo",        # color theme
    dark_mode=False,        # or True for dark
    footer_text="Built with ArielAI",
)

ui.launch()

ChatUI options

Parameter	Type	Default	Description
brand_name	str	"ArielAI"	Name shown in the header
tagline	str	"Powered by open-source AI"	Subtitle below the brand name
brand_logo	str	None	Path or URL to a logo image
accent	str	"indigo"	Color accent (see below)
dark_mode	bool	False	Dark color scheme
show_footer	bool	True	Show a footer below the chat
footer_text	str	"Built with ArielAI"	Footer label
footer_link	str	ArielAI GitHub	URL the footer text links to
extra_css	str	""	Extra raw CSS to inject

from arielai import ChatUI
print(ChatUI.list_accents())

Advanced Usage

Embed in an existing Gradio app

import gradio as gr
from arielai import Chatbot

bot = Chatbot(model="microsoft/DialoGPT-medium")
chat_ui = bot.build()  # returns gr.ChatInterface

with gr.Blocks() as app:
    gr.Markdown("# My App")
    chat_ui.render()

app.launch()

Memory-efficient models (quantization)

bot = Chatbot(
    model="mistralai/Mistral-7B-Instruct-v0.2",
    load_in_4bit=True,  # Requires bitsandbytes + CUDA GPU
)
bot.launch()

Custom backend

from arielai import Chatbot
from arielai.backends import BaseBackend

class MyBackend(BaseBackend):
    def generate(self, message, history, **kwargs):
        return f"You said: {message}"

bot = Chatbot(backend_instance=MyBackend())
bot.launch()
