Overview

The Kraken-Multilingual model and Architecture Kraken is a joint effort between Cognitive Computations, VAGO Solutions and Hyperspace.ai.

Created by Fernando Fernandes Neto, David Golchinfar, Lucas Atkins and Eric Hartford

The Kraken-Multilingual model supports German, English, Italian, French, Swedish, Finnish, Danish and Norwegian language.

The Kraken Architecture is a sophisticated machine learning framework designed for dynamic text generation tasks. It utilizes the Hugging Face transformers library to orchestrate multiple causal language models (CLMs) and intelligently route input through different models based on the context and content of the input text. The architecture is powered by a custom configuration class (KrakenConfig) that facilitates the integration and management of various components such as tokenizers, models, and routing mechanisms.

Features

Dynamic Model Routing: Uses a sequence classification model to route inputs to the most suitable language model based on the input's characteristics. Multiple Language Models: Supports integration of various pre-trained causal language models, allowing for flexible, context-appropriate responses. Customizable Templates: Includes support for input formatting using predefined templates, enhancing the model's adaptability to different conversational contexts. Extensible Configuration: Leverages a custom configuration setup that can be easily extended and adapted for various use cases involving causal language modeling.

How to load and call Kraken-Multilingual model :

from transformers import AutoModelForCausalLM
device = "cuda:0" ## Setup "cuda:0" if NVIDIA, "mps" if on Mac

# Load the model and config:
model = AutoModelForCausalLM.from_pretrained("./kraken_model", trust_remote_code=True)

Call the German expert:

    {'role': 'user', 'content': "Erzähle mir eine kurze Gute Nacht Geschichte in 2 Sätzen."}
    ]

tokenizer = model.tokenizer
input_text = tokenizer.apply_chat_template(messages, tokenize=False)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to("cuda:0")
output_ids = model.generate(input_ids, max_length=150)
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

Call the English expert:

messages = [
    {'role': 'system', 'content': '"You are a helpful AI Assistant'},
    {'role': 'user', 'content': "Find the mass percentage of Ba in BaO"}
    ]

tokenizer = model.tokenizer
input_text = tokenizer.apply_chat_template(messages, tokenize=False)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(device)
output_ids = model.generate(input_ids, max_length=250)
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

Call the Italian expert:

messages = [
    {'role': 'system', 'content': 'Sei un utile assistente AI.'},
    {'role': 'user', 'content': 'Hai qualche idea su cosa potrei fare a Roma?''}
    ]

tokenizer = model.tokenizer
input_text = tokenizer.apply_chat_template(messages, tokenize=False)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(device)
output_ids = model.generate(input_ids ,temperature=0.6, do_sample=True, top_p=0.9,top_k=20, max_length=500)
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

Call the French expert:

messages = [
    {'role': 'system', 'content': 'Vous êtes un assistant IA allemand sympathique et serviable'},
    {'role': 'user', 'content': 'J'aimerais faire du shopping à Paris. Que pouvez-vous recommander?'}
    ]

tokenizer = model.tokenizer
input_text = tokenizer.apply_chat_template(messages, tokenize=False)
print(input_text)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(device)
output_ids = model.generate(input_ids ,temperature=0.6, do_sample=True, top_p=0.9,top_k=20, max_length=250)
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))

Call the Scandinavian expert:

messages = [
    {'role': 'system', 'content': 'Du är en hjälpsam AI-assistent'},
    {'role': 'user', 'content': 'Jag kommer från Tyskland och skulle vilja resa till Sverige. Är en färja över Danmark ett bra sätt att resa?'}
    ]

tokenizer = model.tokenizer
input_text = tokenizer.apply_chat_template(messages, tokenize=False)
input_ids = tokenizer(input_text, return_tensors="pt").input_ids.to(device)
output_ids = model.generate(input_ids ,temperature=0.1, do_sample=True, top_p=0.9,top_k=20, max_length=250)
print(tokenizer.decode(output_ids[0], skip_special_tokens=True))
