You can initialize the wrapper by specifying the provider using the LLMProvider enum and providing the necessary API key and other parameters.

from langchainbridge.core import LLMWrapper
from langchainbridge.providers.provider_enum import LLMProvider

# For Google
google_llm = LLMWrapper(provider=LLMProvider.GOOGLE, api_key='YOUR_GOOGLE_API_KEY')
response = google_llm.invoke("Where was Shivaji Maharaj born?")
print(response)

# For OpenAI
openai_llm = LLMWrapper(provider=LLMProvider.OPENAI, api_key='YOUR_OPENAI_API_KEY', organization='YOUR_ORG_ID')
response = openai_llm.invoke("What NFL team won the Super Bowl in the year Justin Bieber was born?")
print(response)

# For Ollama
ollama_llm = LLMWrapper(provider=LLMProvider.OLLAMA)
response = ollama_llm.invoke("Summarize the text given to you.")
print(response)

# For Anthropic
anthropic_llm = LLMWrapper(provider=LLMProvider.ANTHROPIC, api_key='YOUR_ANTHROPIC_API_KEY')
response = anthropic_llm.invoke("Translate 'I love programming.' to French.")
print(response)
