DeepSeek Releases V4.1-Flash As An Open Model With Lower API Pricing

DeepSeek released DeepSeek-V4.1-Flash on September 10, 2026. The open model is a mixture-of-experts system with 552 billion total parameters, 8 billion active parameters on input and 16 billion on output, and it supports image input. It beat Claude Opus 5 and GPT-5.6 Sol on multiple benchmark tests. Inference efficiency cut KV cache tokens to 1/3.9 of DeepSeek-V4-Flash, and off-peak API pricing is half the peak rate.
