From Google to Autonomous Coding: Scaling Large Language Models with Reinforcement Learning

Welcome! I'm Akansh Shaw, a seasoned researcher with over six years of experience at Google, and today I'll be discussing the future of autonomous coding and the role of reinforcement learning in pushing its frontier.

1. Akansh Shah has worked at Google for over six years, leading research for Palm and serving as a lead researcher in Gemini.
2. He now focuses on pushing the frontier of autonomous coding using reinforcement learning.
3. In 2020, a breakthrough paper discussed scaling laws for large language models, showing a power-law relationship between test loss and compute, data, and parameters.
4. Larger language models generalize well to various domains due to their strong performance on benchmarks.
5. As language models grow larger, emergent behaviors and capabilities appear that were not present in smaller models.
6. An example of this is solving math problems: when large language models output reasoning chains, their answers become correct.
7. This capability has been observed in various domains, including question answering, puzzles, and multitask natural language understanding.
8. With the ability to reason, large language models can follow instructions, leading to successful chatbot applications like ChatGPT and Gemini.
9. These models learn to perform tasks based on reinforcement learning using human feedback data.
10. Inference with these models is inexpensive compared to the high cost of training them.
11. Training large language models can cost tens of millions of dollars, while inference calls are very cheap.
12. Scaling up reinforcement learning for large language models is challenging due to multiple model copies and training loops.
13. Reward hacking is another issue when using neural reward models to determine correct answers.
14. Autonomous coding applications allow for better reward function design because of the ability to verify outputs.
15. Reflection.ai, Shah's company, aims to build superintelligent systems starting with autonomous coding as the root node problem.
16. The mission is to create a team of 35 pioneers in LMS and reinforcement learning to work on this project.
17. In software engineering applications, generating code is just one part of the system; scaling up to generalize across all domains is crucial.
