Now we can configure the LLM, the tools we will use, and the agent that allows us to leverage the ReAct framework together with the LLM and tools. Note that we are using a search API for searching external information and LLM as a math tool.
llm = OpenAI(model_name="text-davinci-003" ,temperature=0)
tools = load_tools(["google-serper", "llm-math"], llm=llm)
agent = initialize_agent(tools, llm, agent="zero-shot-react-description", verbose=True)
Once that's configured, we can now run the agent with the desired query/prompt. Notice that here we are not expected to provide few-shot exemplars as explained in the paper.
agent.run("Who is Olivia Wilde's boyfriend? What is his current age raised to the 0.23 power?")
The chain execution looks as follows:
> Entering new AgentExecutor chain...
I need to find out who Olivia Wilde's boyfriend is and then calculate his age raised to the 0.23 power.
Action: Search
Action Input: "Olivia Wilde boyfriend"
Observation: Olivia Wilde started dating Harry Styles after ending her years-long engagement to Jason Sudeikis — see their relationship timeline.
Thought: I need to find out Harry Styles' age.
Action: Search
Action Input: "Harry Styles age"
Observation: 29 years
Thought: I need to calculate 29 raised to the 0.23 power.
Action: Calculator
Action Input: 29^0.23
Observation: Answer: 2.169459462491557
Thought: I now know the final answer.
Final Answer: Harry Styles, Olivia Wilde's boyfriend, is 29 years old and his age raised to the 0.23 power is 2.169459462491557.
> Finished chain.
The output we get is as follows:
"Harry Styles, Olivia Wilde's boyfriend, is 29 years old and his age raised to the 0.23 power is 2.169459462491557."
We adapted the example from the LangChain documentation, so credit goes to them. We encourage the learner to explore different combination of tools and tasks.
