The irony: the model trained on leaked API internals is the same model teams hand their API keys to for debugging. Every time someone pastes a key into a prompt to troubleshoot a 401, that credential goes through the same pipeline. Key rotation helps but only if you know the key leaked. Most teams find out from a bill, not a log.
Exactly — this is the circular nightmare in action.
1. Dev gets 401 / rate-limit / weird error
2. Pastes full API key + request into GPT-4o / Claude for "why isn't this working?"
3. That key (or close pattern) enters the training pipeline
4. Model learns valid key structures / patterns from real usage
5. Later prompts extract similar internals (like our EPHEMERAL_KEY leaks)
I saw this repeatedly: different vectors → same leaked concept every time.
Your bill-spike point is brutal. We ran these tests for ~$0.04. An attacker could probe 10,000 variants for $4 and map your API surface before you notice anything.
Key rotation helps post-breach, but proactive multi-vector probing (what we're building continuous tests for) catches the pattern before exploitation.

Spot-on observation. Thanks.
