Two Minute Papers looks at DeepSeek V4.1 Flash 1017, the open-weight in-place upgrade DeepSeek released on 17 October. The video description links DeepSeek's release note and clips that users posted of the model at work.

## What it is

'Deepseek's New AI Has A Secret' went up on Two Minute Papers on 28 October 2026. Its description links DeepSeek's release note for DeepSeek-V4.1-Flash-1017 and ten user-posted demo clips from X as sources.

## How it works

DeepSeek's 17 October note says V4.1 Flash 1017 brings stronger benchmark performance, faster task completion and shorter outputs than the previous version, with weights on Hugging Face and ModelScope. It also prices the Search & Fetch tools at $0.75 per 1,000 calls, with billing starting 31 October 2026.

## Why it matters

Open-weight updates like this one land quietly as release notes; the video is a quick way to see what changed and what people are building with the model.
