Gemini API: Basic reasoning

This notebook demonstrates how to use prompting to perform reasoning tasks using the Gemini API's Python SDK. In this example, you will work through a mathematical word problem using prompting.

The Gemini API can handle many tasks that involve indirect reasoning, such as solving mathematical or logical proofs.

In this example, you will see how the LLM explains given problems step by step.

Configure your API key

To run the following cell, your API key must be stored it in a Colab Secret named GOOGLE_API_KEY. If you don't already have an API key, or you're not sure how to create a Colab Secret, see Authentication for an example.

Additionally, select the model you want to use from the available options below:

MODEL_ID

Examples

Begin by defining some system instructions that will be include when you define and choose the model.

Next steps

Be sure to explore other examples of prompting in the repository. Try creating your own prompts that include instructions on how to solve basic reasoning problems, or use the prompt given in this notebook as a template.
