Getting started with the Inflection AI API

Inflection-3 comprises three primary models designed for distinct purposes:

Pi (3.1): the latest model fine-tuned from a Llama base model, including a backstory, emotional intelligence, tool calling, and more. It excels in scenarios such as customer support chatbots or agentic workflows. Set the model or config field in the API request body to "Pi-3.1" to use this model.
Pi (3.0): the legacy model powering our pi.ai and Pi iOS app experiences, including a backstory, emotional intelligence, productivity, and safety. It excels in scenarios such as customer support chatbots. Set the model or config field in the API request body to "inflection_3_pi" to use this model.
Productivity (3.0): the legacy model optimized for following instructions. It is better for tasks requiring JSON output or precise adherence to provided guidelines. Set the model or config field in the API request body to "inflection_3_productivity" to use this model.

How to use Inflection models

First, set up an API key in Authentication
Check out the Playground to try out the different models and techniques.
Check out the API documentation for details on API usage and example commands!
Check out model Pricing.
Set up a new Workspace if desired to collaborate with a team.
Check out Prompt Examples for info on prompts to try out.

Things to try

Pi has been trained to mirror your tone and style, if you use more emojis, so will Pi! Try experimenting with various prompts and conversation styles in the Playground.
