DeepSeek Harness open-sourced: architecture debates, security flaws, and V4 Pro's chaotic launch

2026-08-13 群聊日报

DeepSeek open-sourced DSH, an agent harness where everything is a plugin and the agent loop itself can be swapped at runtime. A deep-dive analysis found this is the only structural edge over declarative frameworks like Codex—betting on self-evolving agents. Four PoC security flaws were also disclosed, including a sandbox escape that exposes SSH keys and .env files. Meanwhile, DeepSeek V4 Pro had a messy launch with inconsistent model versions, pulled weights, and poor real-world instruction following. Gemini 3.7 Flash landed quietly with notable coding gains. OpenAI Astra's math breakthrough faced plagiarism accusations.

Why it matters: DeepSeek officially open-sourced DSH agent framework with a structural differentiator — 'everything is a plugin.' Real test data and same-day community contributions push HKR all three. Score capped at 78 because the source is a chat-group digest, not a first-party announcemen...
