DeepSeek V4.1 Flash Beats Larger Model, Proving Ilya Right
Ilya Sutskever left OpenAI to found SSI and predicted the end of scaling. DeepSeek's new V4.1 Flash model, with a third of the parameters of its flagship V4-Pro, outperforms it on coding benchmarks (74.2 vs 62.7) while activating fewer parameters per token. Starting September 14, all V4-Pro requests route to V4.1 Flash. This validates the shift from model size to efficiency, marking a turning point in AI development.
- DeepSeek V4.1 Flash has 552 billion parameters, activating 8-16 billion per token, while V4-Pro has 1.6 trillion parameters, activating 49 billion.
- V4.1 Flash scores 74.2 vs V4-Pro's 62.7 on DeepSeek's coding tests.
- All V4-Pro requests are rerouted to V4.1 Flash starting September 14.
