DeepSeek announces DeepSeek-V4.1-Flash-1017, claiming stronger benchmarks, faster task completion and shorter outputs than the previous version, live on its website, app and API. It is optimized for DeepSeek Harness (v0.2.1-rc.1 or later), Tencent CodeBuddy and WorkBuddy, and uses reinforcement learning with self-feedback to improve end-to-end project development, from game creation to 3D modeling. The thread also opens the Search & Fetch APIs to everyone, backed by DeepSeek's in-house search engine at $0.75 per 1,000 calls per endpoint, available as server-side tools.

TL;DR DeepSeek ships V4.1-Flash-1017 (better, faster, shorter outputs, RL with self-feedback for full projects) and opens Search & Fetch APIs at $0.75/1k calls.
