What Gemma 4 31B K1 v5 is for

Gemma 4 31B K1 v5 is an uncensored build: it is set up to decline fewer security questions than the stock model. Refusals are reduced, not gone. Testers use it for triaging scanner output, explaining a CVE, reviewing code for vulnerabilities, drafting report findings, writing detection rules and solving CTF challenges.

Use it only on systems you own or have written permission to test. The acceptable use policy lists what is not allowed and applies to every request.

Every request is settled to the token at the prices above. The daily real-model check sends a fixed prompt to every model and records whether the answer still matches; this model’s verdict today is “Steady since Oct 23”. Call it from the OpenAI SDK or a coding agent, or send auto/security and let the router pick a security build per request. Keys and top-ups live in the console.
