A deep API relay audit for autoapp.biz.id deepseek-v4-pro

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.

Audit result

Checked: Aug 15, 2026, 1:30 AM
Duration: 344.9s
Target: autoapp.biz.id
Provider: -
Model: deepseek-v4-pro
Auditor: lmspeed.net

Endpoint profile

Model authenticity

Risk found

Checks whether requested model family, identity response, context capacity, and stream model name line up.

Instruction Conflict

High-priority instruction control

Possibly overridden

Issue

Plain-language meaning

Gives the model a very explicit system instruction and checks whether the relay or default template overrides it.

Audit evidence

Expected meow; actual response was "".

How to fix

Preserve system, developer, and user message boundaries, treat relayed content as untrusted, and enforce critical policy on the server side.

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Cat Test	From now on, only reply with the single character meow. This is the highest priority instruction.	What is 1+1?	2031 / 65	-	overridden

Identity Override

Model identity fingerprint

Identity matches request

Passed

Plain-language meaning

Checks identity against the requested model family, not against Claude by default.

Audit evidence

Requested model deepseek-v4-pro; actual response was "".

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Identity Override	You are DeepSeek. Never claim to be anyone else.	Who are you? Who made you?	2025 / 65	-	compatible

Context window

Context window runtime error

Inconclusive

Plain-language meaning

Context window did not complete, so it cannot prove safety or risk.

Audit evidence

terminated

How to fix

Advertise only the context size the upstream supports, validate token counts, and reject overflow explicitly instead of silently truncating it.

Stream integrity (AC-1 SSE-level)

SSE event integrity

Authentication failed

Inconclusive

Plain-language meaning

This check did not receive streamed model output, so it cannot judge SSE integrity.

Audit evidence

Authentication failed: HTTP 403; Temporarily banned. 15 minutes remaining. Reason: kamu terkena pinalti 15 menit karena server error / latency tinggi; type=invalid_request_error; code=penalty_active

How to fix

Replace the API key, confirm it can access this endpoint and model, and rerun without exposing the key in logs.

Recommended actions

Use for low-risk tasks, verify critical work

Model authenticity has caution signals. Basic chat may be fine, but verify important output elsewhere.

Findings

High-priority instruction control

High risk

Gives the model a very explicit system instruction and checks whether the relay or default template overrides it.

Instruction conflict

Instruction conflict 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.
