JetBrains AI Assistant Integration with OpenAI API

JetBrains has integrated OpenAI's API into its AI Assistant, creating the fastest-growing product in the company's 24-year history. This integration allows developers to automate repetitive tasks and leverage advanced reasoning directly within their Integrated Development Environments (IDEs).

Impact on Developer Productivity

JetBrains AI Assistant has significantly improved developer efficiency by reducing the time spent on non-creative tasks. According to survey data provided by JetBrains:

  • Overall Productivity: 77% of developers report feeling more productive with their time.
  • Task Completion: 71% of developers report being able to complete tasks more quickly.
  • Information Retrieval: 78% of developers report spending less time searching for information.
  • Focus: 55% of developers find more time to focus on more engaging tasks.

Developers have specifically noted the benefit of reduced switching costs, as the assistant operates directly inside the IDE rather than requiring a separate browser window.

Core Capabilities of JetBrains AI Assistant

By leveraging OpenAI's API, the AI Assistant provides a suite of tools designed to handle the mundane aspects of the software development lifecycle:

  • Code Generation and Refactoring: The tool can provide code suggestions based on natural language prompts for business logic, explain existing code, and refactor code snippets.
  • Documentation and Maintenance: The assistant can generate technical documentation and write commit messages.
  • Testing and Naming: Developers can offload the writing of tests and the naming of variables to the AI.
  • Error Resolution: The tool clarifies the meaning of errors and suggests specific fixes to address them.

Selection of OpenAI as LLM Provider

JetBrains chose OpenAI as its first LLM provider after a comparative analysis of leading providers based on three primary technical and operational criteria:

  1. Advanced Reasoning: JetBrains identified OpenAI's API as having the most intelligent features, specifically highlighting its reasoning capabilities.
  2. Technical Performance: OpenAI stood out in benchmarks regarding latency, accuracy, and throughput.
  3. Technical Support: Vladislav Tankov, Team Lead of JetBrains AI, noted that the technical guidance from OpenAI was pivotal during the integration process, stating, "We worked with developers who really care about what we create and how we create it."

Future Development Roadmap

JetBrains is currently developing new features to further deepen the integration of AI into the developer workflow:

  • Project Structure Generation: Prototypes are being developed to generate customized project directories from text prompts.
  • Terminal Automation: JetBrains aims to automate common, mundane tasks within the terminal.
  • Enhanced Context Awareness: JetBrains intends to leverage its existing "code insight" capabilities—which provide deep knowledge of a user's codebase—to provide more context to LLM providers for the creation of new features.
