Interesting to see the analysis between Inference scaling and LLM safety!

😲 Not only reasoning?! Inference scaling can now boost LLM safety! 🚀 Introducing Saffron-1: - Reduces attack success rate from 66% to 17.5% - Uses only 59.7 TFLOP compute - Counters latest jailbreak attacks - No model finetuning On the AI2 Refusals benchmark. 📖 Paper:…
