Then vs. Now (News report): Then: OpenAI announced on 2026-10-26 that CodeRabbit is using GPT-6.1 Sol as the primary model in its security agent. Now: OpenAI stated that CodeRabbit reports using GPT-6.1 Sol to flag security-related issues across thousands of repositories and organizations, with human reviewers deciding which changes ship.
OpenAI announced on 2026-10-26 that CodeRabbit is using GPT-6.1 Sol as the primary model in its security agent, extending review beyond individual code changes to risks across complex codebases ( OpenAI ). CodeRabbit's system also uses other frontier models and security tooling, according to the announcement ( OpenAI ).
OpenAI explained that a pull request can affect shared libraries, dependencies and safeguards elsewhere in an application, and that GPT-6.1 Sol helps CodeRabbit connect behavior across files and components to surface potential security issues ( OpenAI ). During pull-request review, the model helps analyze changes as developers work ( OpenAI ). CodeRabbit Secure extends the investigation to linked repositories, such as a shared authentication library ( OpenAI ).
The announcement states that CodeRabbit's review is independent of the agent that wrote the code and complements established scanners ( OpenAI ). For user-selected findings, CodeRabbit Secure can attempt exploit verification in an isolated sandbox without testing production systems ( OpenAI ). OpenAI added that human reviewers remain responsible for deciding which changes to ship ( OpenAI ).
CodeRabbit's own page states that every finding goes through reachability, exploitability and blast radius analyses, and that findings no attacker can reach are capped at low severity ( Coderabbit (official statement) ). It also states that a verification pass rejects findings that are extremely hard to exploit ( Coderabbit (official statement) ). Fix with AI drafts a fix in a pull request, and a person on the customer's team reviews and merges each fix, as CodeRabbit never merges one on its own ( Coderabbit (official statement) ).
On data handling, CodeRabbit states that it never trains models on customer code and shares it with OpenAI, Anthropic or both only for reviews ( Coderabbit (official statement) ). Cached data for private repositories is encrypted and expires within seven days, according to the company ( Coderabbit (official statement) ). PR Security Review, Blast Radius, Security Architecture Review and the Attack Surface Map come with the Advanced and current Enterprise plans, and new organizations get a 14-day Advanced trial ( Coderabbit (official statement) ).
