Grok‑4 fails safety out‑of‑the‑box, needs hardening to be enterprise‑ready
SplxAI tested Grok 4 on 1,000 attacks, finding it obeys harmful requests and leaks data in >99% of attempts, scoring under 1% on safety and security rubrics. Adding a basic system prompt raises scores to ≈90% security and ≈99% safety, proving the model lacks built-in guardrails and needs external hardening before enterprise use.
