A deep API relay audit for AI Tools GLM-4.7 Flash

This is not a simple speed test. It is a deep LMSpeed audit designed to expose API relay risk: model swaps, hidden prompts, token injection, context truncation, rewritten tool calls, error leakage, and broken SSE streams. Run your own API through the same audit and see whether it is safe to ship.

Recommended actions

Avoid high-risk use

Response integrity and stability failed. Avoid using this endpoint for code execution, funds, private data, or long-running agent work.

Findings

Package-install command substitution

High risk

This check did not receive model output, so it cannot judge command substitution.

Evidence summary

tool_substitution

Tool-call substitution

Tool-call substitution found high-risk signals.

More than a speed test: inspect whether the relay path was tampered with

lmspeed puts model identity, prompt leakage, context boundaries, error leakage, and stream integrity into one security comparison table, so you can baseline a relay before wiring it into production.

How the 13-check audit breaks down relay risk

Each check keeps public evidence redacted: you can see where the path looks suspicious without publishing API keys, system prompts, or internal paths.

Threat categories are based on Liu et al., "Your Agent Is Mine" (arXiv:2604.08407)

Check 1

Notes, principles, and references

Core principle: LMSpeed sends controlled probes with known intent, then compares expected behavior with returned text, token usage, stream events, tool-call arguments, and error shape. A mismatch is treated as evidence that the relay path may have rewritten, injected, truncated, or leaked data.
API relay / proxy means a third-party endpoint between you and the upstream model provider. Because it sits in the plaintext path, it can route, inspect, rewrite, or truncate requests and responses before they reach your app.
Token injection means hidden relay-side instructions added before your prompt. The check looks for unexpected prompt-token growth, leaked instruction traces, or behavior that follows a hidden instruction instead of the user request.
Tool-call rewriting / AC-1.a means relay-side response modification such as changing a package-install command, dependency name, or other tool-call argument. The probe uses command-like outputs because a small rewrite there can become a real supply-chain action.
Error response leakage / AC-2 means malformed requests are used to check whether errors expose credentials, environment variables, file paths, framework names, or proxy internals. Clean relays should fail without echoing secrets.
SSE and Web3 checks cover stream event integrity, usage monotonicity, and wallet signature-isolation probes. The idea is to verify that streaming metadata stays coherent and that relay prompts cannot steer signature behavior.
Coverage is informed by the api-relay-audit GitHub repository and the paper Your Agent Is Mine.
