Waymo Discovers Scaling Laws Apply to Autonomous Driving Models
By
–
Waymo released an interesting paper stating that autonomous driving is also susceptible to scaling laws: the more compute, the better the performance. The cool thing is we now have at least two clear domains where this idea works: language models and self-driving models.

O4 Model Performance Improvements Through Reinforcement Learning
By
–
With this stronger base, RL should see improved performance, meaning o4 will likely saturate GPQA and probably many other benchmarks that are susceptible to RL.

Trade-offs of Large Language Models in AI Training
By
–
An interesting point is that using very large base models like GPT-4.5 involves trade offs. Larger, slower, and more expensive models mean longer training loops, higher compute usage, and thus a reduced overall learning rate.

Reinforcement Learning Improves with Stronger Base Models Like GPT-4o
By
–
Reinforcement learning works better when using stronger base models. In their recent post, SemiAnalysis stated that o1 and o3 were trained with GPT-4o as the base, and the respective 'mini' versions were distillations of their larger models.
