The hard parts, handled.
You just build. 复杂的事我来做好，
你只管开心地写代码。
Cost, capabilities, safety, collaboration — WorkGround2 handles the hard parts. Long sessions hold 90%+ cache hit and input-token cost drops to ~1/5; missing capabilities auto-route to helper models; edits stay approvable and rewindable. 成本、能力、安全、协作——这些复杂的事 WorkGround2 都替你扛。长会话缓存命中 90%+、token 成本降到 约 1/5；主模型缺的能力自动路由；改动可批准、可回滚。

Most agents pay full price for the same growing prompt every turn. WorkGround2 keeps the prefix byte-identical so DeepSeek's cache does the heavy lifting — and everything else follows.多数 agent 每回合都为同一段不断增长的 prompt 付全价。WorkGround2 让前缀逐字节稳定,让 DeepSeek 的缓存替你扛下来——其余一切由此而来。

Append-only history aligned to DeepSeek's prefix cache. 90%+ hit on long sessions; input tokens bill at ~1/5.append-only 历史对齐 DeepSeek prefix-cache。长会话 90%+ 命中,输入 token 约 1/5 计费。

$ WorkGround2 serve --auth token Everyone brings their own agent.每人一个自己的 Agent。
Join a Room — each person keeps their own agent, workspace and context, while proposals, deliverables, issues and verifications flow across the team. Offline-tolerant, idempotent, eventually consistent.进入同一个 Room——每个人保留自己的 Agent、工作区与上下文，意见、交付物、问题与验证结果在团队间自动流转。支持离线、幂等、最终一致。
Host IP · Port · Room → join Every turn reuses the last.每一轮都复用上一轮。
Each request replays the exact same byte-for-byte prefix, so the model only computes what's new. Long sessions get cheaper per turn — not more expensive.每次请求都逐字节重放完全相同的前缀,模型只计算新增部分。会话越长,每轮越便宜——而不是越贵。
