JetBrains AI Assistant employs different large language models (LLMs) and transparently makes them work for you as a product user. It is powered by OpenAI and Google as the primary third-party providers, as well as by a number of JetBrains proprietary models. With a JetBrains AI service subscription, AI Assistant is available in IntelliJ IDEA, PyCharm, PhpStorm, ReSharper, and other JetBrains IDEs, as well as in Fleet as a supplemental feature. Also included is Junie, which can take care of planning, writing, refining, and testing your code. While AI Assistant supports developers to code faster, Junie operates more independently and collaboratively with a developer, solving larger tasks step by step.
