DeepSeek Harness

AgentSky is the only managed cloud where you can run DeepSeek Harness without hosting it yourself. DSH is DeepSeek's first-party coding agent, purpose-built for DeepSeek V4 Pro and DeepSeek V4 Flash — generic wrappers do not correctly handle DSH's SSE tool-name assembly. Arena coverage is expanding. $3 free credit, no card.

DeepSeek Harness (DSH) is DeepSeek's first-party agentic coding assistant, tuned to work natively with DeepSeek V4 Pro, DeepSeek V4 Flash, Kimi K3, and GLM-5.2. It is the only harness purpose-built for DeepSeek's model architecture and correctly handles DSH's SSE tool-name assembly, which generic wrappers do not.
