Inflection AI
Maker of the Pi assistant and Inflection-3 models, offering a developer API and an enterprise AI system you can host yourself.
What is Inflection AI?
Inflection AI builds conversational language models, including Pi, the assistant behind the pi.ai site and the Pi iOS app. Developers can call the Inflection-3 family through a commercial API at developers.inflection.ai, with a Pi model for emotionally aware conversation, a Productivity model tuned for instruction following and JSON output, and a Pi 3.1 preview in beta for tool calling and agentic work. A browser playground, API keys, workspaces and a usage dashboard come with the developer portal. For large organisations, Inflection for Enterprise offers fine-tuned models that can run on-premises, in the cloud or in a hybrid setup, with Intel Gaudi 3 accelerators supported, and Agentic Workflows built with UiPath to trigger automations. The developer portal has a pricing section but the figures were not shown, so check the portal or contact the company for rates.
