BASIC QUALIFICATIONS:
- You believe truth-seeking AI is the most important and challenging problem.
- You are obsessed about building incredibly useful models through post-training and RL techniques.
- You are a power user of AI models and eager to push the boundaries of what’s possible with reinforcement learning and alignment methods.
