OpenAI’s Strawberry and inference scaling laws
Language model generation is a naive form of search. It is sampling from a distribution of potential tokens in order to select the next output. There are many ways we can spend more compute to better refine this distribution, most of which are not being taken seriously enough. Inference spend per token represents a standalone scaling law independent of underlying model size. Inference spend has been demonstrated to more clearly improve capabilities than any fancy fine-tuning. Many of of the most important moments in the history of AI have come from inference-heavy algorithms. AlphaGo solved Go much like DeepBlue won at Chess. To simplify some things, they scaled up compute when searching over a reasonable representation of the world. We should have basic rules of thumb for each model version about how much more inference time compute it takes to match the performance of the next base model version. For only 10 times the inference budget, can GPT 3.5 match GPT 4? Epoch AI has an illustr
