DeepSeek just released and open-sourced DeepSeek-V4.1-Flash-1017, a coding model trained with self-feedback reinforcement learning to tackle end-to-end projects from 3D modeling to full games. It promises faster task completion with tighter outputs across web, app, and API. DeepSeek also opened its proprietary Search and Fetch APIs, which remain free for API users through October 31, 2026.
DeepSeek just rolled out DeepSeek-V4-Flash-Vision-Exp on its API platform. The experimental multimodal model retains V4-Flash's text and reasoning chops while closing in on Opus-4.8 on multimodal agent benchmarks. Images cap out at 384 tokens each, and a new Files API lets developers upload once and reuse across calls.
DeepSeek just open-sourced DeepSeek Harness (dsh), an agent framework built entirely on an "everything-is-a-plugin" architecture. Powered by Cordis, it turns models, tools, and sandboxes into modular extensions and spins up an out-of-the-box local Web UI. It is currently in active developer preview, so expect breaking changes ahead.
