DeepSeek ships V4.1-Flash-1017: stronger benchmarks, faster tasks, shorter outputs

DeepSeek officially released DeepSeek-V4.1-Flash-1017, now live on its website, app, and API.
- The company calls it a Pareto improvement over the previous version: stronger benchmark performance, faster task completion, and shorter outputs.
- It is optimized for coding/agent tools including DeepSeek Harness, Tencent CodeBuddy, and WorkBuddy; users are advised to upgrade to DeepSeek Harness v0.2.1-rc.1 or later.
- Quoting user @AlchainHust notes the version number stayed the same (only the date changed), but argues the jump over the early-year V4 is at least "V4.5 Pro"-level.
