Verbessern Sie die Qualität der Trainingsdaten für die Codierung von LLMs

SonarSweep shares its underlying code analysis engines with SonarQube and SonarQube Cloud, but it is a completely separate service and does not integrate with either product. It is not an add-on, extension, or feature of any SonarQube edition.

Where SonarQube and SonarQube Cloud help development teams detect quality and security issues in their own application code during development and CI/CD, SonarSweep processes large code datasets that AI companies use to train models. The relationship is a shared technological foundation — Sonar's analysis engines — applied to an entirely different use case and a different customer.

Coding LLMs are pre-trained on raw public open-source code — code that's full of bugs, vulnerabilities, and poor patterns. Models don't just absorb these flaws; they amplify them in everything they generate. SonarSweep fixes this at the source by cleaning training data before a model ever sees it.

It reduces security vulnerabilities in model output by up to 67% and cuts bugs by up to 42%. It also handles a subtler problem: naively removing flawed code can skew language distribution in a dataset, so SonarSweep rebalances after cleaning to preserve model proficiency across all languages. And by addressing quality upfront, it eliminates the need for costly post-training correction passes.

SonarQube for IDE (formerly SonarLint) is a developer productivity tool that runs inside editors like VS Code, IntelliJ, and Eclipse, giving individual developers real-time feedback on quality and security issues as they write code. It operates at the developer level, in the IDE, during active development.

SonarSweep is not a developer tool at all. It is a data processing service for AI companies that are training or fine-tuning coding LLMs. It does not run in an IDE, does not provide feedback to developers, and is not part of a development workflow.

Yes — this is the core purpose of SonarSweep. The quality of code a language model generates is directly shaped by the quality of the data it trained on. A model that learned from code full of vulnerabilities and bugs will reproduce those patterns at scale. SonarSweep intervenes at the data stage, before training, to raise the quality floor of what the model learns from.

Models trained on SonarSweep-prepared datasets have demonstrated up to 67% fewer security vulnerabilities and up to 42% fewer bugs in their generated code compared to models trained on unswept data — with no degradation in functional performance. This was validated on the GPT-OSS-20B model.

SonarSweep supports 35+ programming languages, drawing on the full breadth of Sonar's code analysis engines — the same engines that power SonarQube and SonarQube Cloud.

In the context of LLM training data, this means SonarSweep can analyze, filter, and remediate code across all the languages that typically appear in large public code datasets: common back-end languages, front-end languages, scripting languages, systems languages, and more. Across these languages, it can identify and automatically fix over 6,700 distinct types of quality and security issues.

SonarSweep doesn't produce code changes for developers to review in pull requests. It processes and delivers cleaned training datasets to AI companies. Governance in this context sits with the AI team — validating dataset quality and model output before using the swept data in a training run.

No. SonarSweep has no connection to any SonarQube edition. It is a separate product for companies building or fine-tuning coding LLMs — not a feature unlocked through any SonarQube subscription tier.

The ROI is for AI companies, not development teams. Models trained on SonarSweep-processed data produce up to 67% fewer security vulnerabilities and up to 42% fewer bugs — with no loss in functional performance. It also reduces training cost by addressing data quality upfront, eliminating expensive post-training correction cycles.
