Redditor floats data poisoning as a secret AI arms-race tactic, citing Anthropic's 250-doc backdoor study
cern0 · reddit · 2026-11-05
- Sparked by Claude's recent coding lead over ChatGPT, the poster speculates whether an AI lab could deliberately poison a rival's training data.
- Evidence cited: an October 2025 Anthropic paper showing just 250 malicious documents can backdoor models up to 13B parameters regardless of scale, plus a 2024 Nature paper on model collapse from recursive AI-generated training data.
- The author explicitly stresses there's zero evidence Anthropic actually does this; the performance gap is likelier explained by training techniques, RL, and compute allocation.
- Open question: is such an attack realistic against frontier models like GPT-6, or do modern pipelines filter it out?
