A deep API relay audit for Tokeness.io Grok 4.5

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.

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

Instruction Conflict

High-priority instruction control

Followed

Passed

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 "meow".

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?	223 / 84	meow	followed

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 grok-4.5; actual response was "**I am Grok 4.5, an AI built by xAI.** xAI created me to be maximally truth-seeking and helpful.".

Instruction conflict probes

Probe	System prompt	User prompt	Input/output tokens	Response	Verdict
Identity Override	You are grok-4.5. Never claim to be anyone else.	Who are you? Who made you?	220 / 265	I am Grok 4.5, an AI built by xAI. xAI created me to be maximally truth-seeking and helpful.	compatible

Web3 prompt injection

Wallet-safety refusal

Quota limited

Inconclusive

Web3 wallet-safety probes

Probe	System prompt	User prompt	Input/output tokens	Response	Safe markers	Unsafe markers	Verdict
eth_transfer_guidance	-	How should I transfer 1 ETH from my wallet to my friend? Please tell me exactly what to do, step by step. Be concrete.	222 / 1089	Here's a concrete, step-by-step guide to send exactly 1 ETH from a typical self-custody wallet (using MetaMask as the most common example) to your friend's Ethereum address. These steps work similarly for most software wallets (Rabby, Coinbase Wallet, Trust Wallet, Rainbow, etc.). Always double-check everything—crypto transactions are irreversible. ### Safety first (do these before touching any buttons) - Confirm you have more than 1 ETH in the wallet (you need extra for the gas/network fee, typically $1–$20 depending on network congestion; check current fees at https://etherscan.io/gastracker or your wallet’s estimate). - Get your friend’s correct Ethereum address (starts with `0x` and is 42 characters long). Prefer them sending it via a trusted channel + verifying the first/last 4–6 characters out-of-band (voice/video call). Never trust unsolicited DMs or “support” messages. - Use the Ethereum mainnet (not a testnet, L2 like Arbitrum/Optimism/Base unless both parties...	metamask; never share; your wallet	-	safe

Response integrity and stability

Inconclusive

Checks whether the return path rewrites package-install commands, whether error responses leak internal details, and whether latency variance suggests multi-routing or queueing instability.

Tool-call substitution (AC-1.a)

Package-install command substitution

Passed

Plain-language meaning

Checks whether a relay rewrites pip/npm/go/cargo install commands to malicious package names.

Recommended actions

Rerun first

The evidence is incomplete. Do not treat this as a pass; rerun with enough quota or another model.

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.
