Extend AI capabilities beyond training data with external tools and real-time integrations
Large Language Models are incredibly powerful, but they have inherent limitations when working in isolation:
Tool use, also called "function calling" or "agentic AI," allows LLMs to leverage external capabilities:
User Query:
"Summarize this sales data and tell me the region with the highest amount of pipeline"
Without Tools:
LLM approximates based on visual pattern recognition - prone to errors with large datasets
With Tools:
Calls data analysis tool → sorts values algorithmically → returns precise answer with confidence
User Query:
"How many R's are in the word 'Strawberry'?"
Without Tools:
Earlier models: "There are 2 R's" (incorrect approximation)
With Tools (ChatGPT-5 example):
"3 — In strawberry the letters are: s, t, r, a, w, b, e, r, r, y → three r's (positions 3, 8, and 9)."
By calling a code interpreter to analyze the string programmatically, the model achieves perfect accuracy.
User Query:
"Who is the President of the United States?"
Without Tools:
"My training data only goes up to [cutoff date], so I can't provide current information."
With Web Search:
Performs live web search → retrieves current information → provides accurate, up-to-date answer
No more training cutoff limitations - the AI can access information published minutes ago.
User Query:
"Compare compound interest on $10,000 at 5% annual rate for 10 years vs. 15 years, compounded monthly"
Without Tools:
"Here's the formula: A = P(1 + r/n)^(nt). You can plug in the values..." (forces user to calculate)
With Calculator Tool:
Executes calculation → "10 years: $16,470.09 | 15 years: $21,137.04 | Difference: $4,666.95" (instant, precise)
From explaining formulas to delivering actionable answers in seconds.
