GLM-5.3 Flash Cybersecurity is set up for security work: it answers offensive-security, malware-analysis and red-team questions the stock models refuse. Use it under the acceptable-use terms.

Every request is routed to the build’s live route and 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”.

Use it from the OpenAI SDK, from SillyTavern or Janitor, or from a coding agent. Keys and top-ups live in the console.
