JetBrains AI services are powered by a combination of AI models hosted directly on JetBrains servers and AI models provided by external AI services providers (except for JetBrains AI Enterprise, which is powered by a single AI service provider).
1. The JetBrains AI platform currently hosts the following AI models:
| Model name | Trained by | Notes |

The JetBrains AI platform also hosts other open-source models operated by JetBrains. The models listed in this section run on JetBrains infrastructure; their inputs and outputs are not shared with the parties that trained them.
2. JetBrains AI services use the third-party language model service providers listed below as AI subcontractors. Depending on the service in which you use JetBrains AI, your JetBrains AI configuration, the selected model, and the hosting route, your inputs and data may be processed by one or more of these subcontractors. Not every subcontractor is involved in every request.
