Is AI making you dizzy? A lot of industry insiders are feeling the same. R1 just came out a few days ago out of nowhere, and then there’s o1 and o3, but no o2. Gosh! It’s hard to know what’s going on. This post aims to be a guide for recent AI developments. It’s written for people who feel like they should know what’s going on, but don’t, because it’s insane out there.
Timeline of AI Developments
In recent months, the AI landscape has been rapidly evolving, with new models like R1 emerging unexpectedly. This has left many industry insiders scrambling to keep up. The key to understanding these developments lies in distinguishing between reasoning models and AI agents. Reasoning models are designed to "think" before responding by generating tokens, while AI agents combine these models with software to interact autonomously with the world.
Reasoning Models vs. AI Agents
Reasoning models are crucial because they enable planning, supervision, and validation. However, they are often confused with AI agents, which require reasoning to function effectively. The current challenge is to make reasoning more cost-effective, as agents may operate continuously, leading to high expenses. R1 stands out by being approximately 30 times cheaper than o1 while maintaining similar performance.
The Significance of R1
R1 is significant for several reasons. It is open source, allowing the global community to innovate and iterate quickly. This has led to a flurry of activity, with some claiming to recreate R1 for as little as $30. Importantly, R1 has simplified the path forward by demonstrating that basic reinforcement learning (RL) is effective, challenging more complex ideas like DPO and MCTS.
AI Trajectory and Scaling Laws
The trajectory of AI is marked by the decline of pretraining scaling laws, which suggested that increasing data and compute would improve models. Instead, new scaling laws have emerged, focusing on inference time. This means that the longer a model "thinks," the better it performs. R1 exemplifies this by using simple, single-line chain of thought (CoT) trained by RL.
Reinforcement Learning and Model Distillation
R1 employs Group Rewards Policy Optimization (GRPO) to enhance its reasoning capabilities during inference. This approach is straightforward, relying on basic reward functions for accuracy and format. Interestingly, R1-Zero, a variant from DeepSeek, has shown that any reinforcement learning method can be effective, provided the model exceeds a certain size (1.5B parameters).
Model distillation is another critical aspect, where a teacher model generates training data for a student model. R1 has utilized previous checkpoints of itself for this purpose, iterating between Supervised Fine Tuning (SFT) and RL to improve. This process suggests that the student model can potentially surpass the teacher, challenging fears of model collapse.
Predictions for 2025
Looking ahead, AI development shows no signs of slowing down. Despite one scaling law slowing, four new ones have emerged, indicating continued acceleration. The geopolitical implications are significant, with AI becoming a central factor in political dynamics, particularly between China and the USA. The concept of "distealing," or unauthorized model distillation, highlights the political nature of AI.
Conclusion
The rapid pace of AI development can be overwhelming, but R1 offers clarity where there was previously opacity. As the future of AI becomes more transparent, it is clear that advancements will continue at an accelerated rate.
