Opus 4.8

Claude Opus

Maximum intelligence for critical applications

Opus is Anthropic's most capable model. It applies deeper reasoning across longer contexts, which matters when you're scanning complex applications with interleaved auth logic, nested API calls, and subtle data-flow vulnerabilities that only emerge from a thorough read of the whole response chain.

What Claude Opus brings to a scan

Where it excels

Deep analysis

Opus maintains context across an entire crawl session. It notices that a token returned in step 3 is being accepted in a privileged endpoint in step 11, the kind of cross-request reasoning that narrower models miss.

Complex vulnerability classes

SSRF chains, second-order SQL injection, OAuth flow manipulation, business logic bypasses. Opus finds issues that require holding a mental model of the whole application rather than individual endpoints.

Highest confidence accuracy

Opus produces the most accurate confidence scores of any model we support. When Opus flags something at 0.95+, it's almost always a real issue. Signal-to-noise is at its best here.
