Summary

DeepSeek released V4-Flash-0731, a 304 billion parameter (a number that represents the size/complexity of the AI model) model with improved agentic capabilities (features that let the AI act autonomously to complete tasks). The model offers competitive pricing at $0.14 per million input tokens and $0.27 per million output tokens (tokens are small units of text), and performs better on intelligence benchmarks than some larger competing models.
