They created a "no-training" method that costs $18 and outperforms RL networks, where training costs $10k.
🟢 What they done?
It's called "Training-Free GRPO". The essence is that you can achieve Reinforcement Learning-level performance without updating a single parameter at all.
Instead of expensive gradient updates, the model "learns" through Semantic Advantage: this is a text memory (in natural language) of its own successes and failures.
☞ No gradients: the model remains frozen.
☞ Self-correction: it analyzes its rollouts and extracts "what worked" into a text library of experience.
☞ Wild efficiency: it gives fine-tune-level results on just 100 examples.
☞ Price: about $18 (instead of $10,000+ for classic RL).
☞ Essentially, it's an agent that writes its own "guide to passing" in real time.
