Free LLM endpoint shows context leakage under concurrent load

A test of a free LLM endpoint revealed potential context integrity issues under concurrent load. When sending 100 interleaved prompts on unrelated topics (pizza recipes and Rust programming), approximately 7% of the responses showed signs of context leakage. This contamination was not deterministic and appeared to occur only when the server was under stress, suggesting that free LLM services may not reliably isolate individual user sessions. AI

    I Sent 100 Concurrent Prompts to a Free LLM. Two Sessions Started Bleeding Into Each Other.

    <p>Have you ever trusted a free AI endpoint to keep every conversation sealed in its own little bubble? I spent 48 hours on MonkeyCode's free server firing off 100 parallel requests about two deliberately unrelated topics, and the results forced me to add a "context integrity" ch…
