Instructions to use OpenGenerativeAI/Bifrost with libraries, inference providers, notebooks, and local apps. Follow these links to get started.

Libraries

How to use OpenGenerativeAI/Bifrost with Transformers:

# Use a pipeline as a high-level helper
from transformers import pipeline

pipe = pipeline("text-generation", model="OpenGenerativeAI/Bifrost")
messages = [
    {"role": "user", "content": "Who are you?"},
]
pipe(messages)

# Load model directly
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("OpenGenerativeAI/Bifrost")
model = AutoModelForCausalLM.from_pretrained("OpenGenerativeAI/Bifrost")
messages = [
    {"role": "user", "content": "Who are you?"},
]
inputs = tokenizer.apply_chat_template(
	messages,
	add_generation_prompt=True,
	tokenize=True,
	return_dict=True,
	return_tensors="pt",
).to(model.device)

outputs = model.generate(**inputs, max_new_tokens=40)
print(tokenizer.decode(outputs[0][inputs["input_ids"].shape[-1]:]))

Bifröst

Bifröst is an advanced AI model built upon Phi-4 integrated into the Llama architecture, specifically fine-tuned for secure and efficient enterprise-grade code generation. Designed to meet rigorous standards of safety, accuracy, and reliability, Bifröst empowers organizations to streamline software development workflows while prioritizing security and compliance.

Model Details

Model Name: Bifröst
Base Architecture: Phi-4 adapted to Llama
Application: Enterprise Secure Code Generation
Release Date: 07-March-2025

Intended Use

Bifröst is designed explicitly for:

Generating secure, efficient, and high-quality code.
Supporting development tasks within regulated enterprise environments.
Enhancing productivity by automating routine coding tasks without compromising security.

Features

Security-Focused Training: Specialized training regimen emphasizing secure coding practices, vulnerability reduction, and adherence to security standards.
Enterprise-Optimized Performance: Tailored to support various programming languages and enterprise frameworks with robust, context-aware suggestions.
Compliance-Driven Design: Incorporates features to aid in maintaining compliance with industry-specific standards (e.g., GDPR, HIPAA, SOC 2).

Limitations

Bifröst should be used under human supervision to ensure code correctness and security compliance.
Model-generated code should undergo appropriate security and quality assurance checks before deployment.

Ethical Considerations

Users are encouraged to perform regular audits and compliance checks on generated outputs.
Enterprises should implement responsible AI practices to mitigate biases or unintended consequences.
