Code Examples

Install
pip install google-cloud-aiplatform
API key
GOOGLE_CLOUD_PROJECT
Model ID
vicuna-13b-16k

For Google-published models use the model name directly, e.g. "gemini-2.0-flash-001". For third-party publishers (Anthropic, Meta, etc.) use the full publisher path, e.g. "publishers/anthropic/models/claude-3-5-sonnet-v2@20241022".

import os
import vertexai
from vertexai.generative_models import GenerativeModel

# Reads GOOGLE_CLOUD_PROJECT from env; authenticates via Application Default Credentials
vertexai.init(project=os.environ["GOOGLE_CLOUD_PROJECT"], location="us-central1")
model = GenerativeModel("vicuna-13b-16k")
response = model.generate_content("Hello")
print(response.text)

About Vicuna 13B 16K

The Vicuna 13B v1.5 16K model by LMSYS is an advanced conversational AI built on the transformer architecture, fine-tuned from Llama 2. It features 13 billion parameters and handles up to 16,000 tokens in context, making it suitable for diverse tasks like chatbots and content generation. Trained on 125,000 conversations from ShareGPT, it excels in generating coherent text and engaging dialogue but may struggle with domain-specific knowledge and nuanced context. Despite potential biases, it represents a significant step forward in conversational AI.
