DeepSeek V4.1 Flash发布：性能超GPT-5.6 Sol

Whats really exciting about DeepSeek 4.1 Flash its insane efficiency and pricing.

It matches or beats GPT-5.6 Sol on several coding and agent benchmarks, according to DeepSeek’s tests, at a fraction of the token price (-94%!)

For example: on DeepSWE, a software engineering benchmark: - Previous V4-Flash: 54.4% - New V4.1-Flash: 74.2% - GPT-5.6 Sol: 73.0%

DeepSeek also cut prices versus V4-Flash: 32% for fresh input, 57% for cached input and 9% for output.

Even at peak rates, Flash charges $1.20 per million output tokens versus Sol’s $20. That is 94% less. Off-peak, it drops to $0.60.

A new architecture makes reading large inputs cheaper, while sharing and compressing stored context reduces memory requirements. Particularly useful for agents repeatedly reading code, documents and tool results.

DeepSeek is truly back in the price war. This is the real moat.
