Chinese LLM API Security Guide: Keys, Gateways, Prompt Injection, and Logs

When integrating DeepSeek, Qwen, Kimi, MiniMax, GLM, or Doubao, security should be designed before production traffic begins.

Key management

Keep provider keys server-side. Use scoped internal keys for teams, users, and applications.

Prompt injection

Do not let the model decide permissions. Validate tool calls and filter retrieved content before it reaches the model.

Logging privacy

Prompt logs may contain sensitive data. Separate metadata logs from raw content, and apply retention limits.

Gateway controls

A gateway can centralize model access, quotas, audit logs, rate limits, and fallback rules.

Final thoughts

Chinese LLM API security is similar to other LLM security, but vendor governance and data-flow clarity are especially important for Western teams.
