For questions that require fetching data from multiple sources, time (and tokens) add up fast. The <a href="https://github.com/oshea00/monty-example">monty-example</a> project explores a different approach: let the model <em>write code</em> that orchestrates tool calls and executes that code in a sandbox running within your code!</p>
