EvoX Genesis 用持久项目代替持久智能体，DeepSeek V4 Flash 花 44 美元写了能过测试的 C 编译器，MESA 提速 6.87 倍。
EvoX Genesis 提出以持久递归世界组织软件开发，用 DeepSeek V4 Flash 在 120 小时内构建了约 25 万行 Rust 版 C 编译器，花费仅 44 美元。该编译器通过完整 c-testsuite 及大部分 LLVM 和 Csmith 测试。在 GLM 5.2 生成的另一编译器世界中，即使反复替换开发代理，测试性能仍保持不变。Genesis 还将 13 个 MESA 模块（超 10 万行 Fortran）重写为近 9 万行 Rust，六个数值工作负载中位数加速达 1.55 至 6.87 倍。
Persistent Recursive Worlds Enable Autonomous Software Evolution
Complex software systems develop over timescales that exceed the lifespan of any individual coding agent. Most agentic software systems preserve continuity through persistent sessions, memories, managers or shared context. We introduce EvoX Genesis (hereafter, Genesis), which instead makes the software project persistent while allowing local agents to remain finite-lived. Genesis represents software as a persistent recursive world: each local world is situated by an accepted version and a repository path, finite-lived agents propose local changes, recursive delegation moves work across paths, and only accepted consequences advance the persistent version history. We evaluate this organization across formation, continuation and redevelopment. Starting from a repository with no compiler implementation, Genesis used DeepSeek V4 Flash to build a Rust-based C compiler with about 250k tracked lines; the run lasted over 120 hours, archived over 1,000 agent episodes and incurred only US$44 in model-token charges. The compiler passed the complete c-testsuite and most LLVM and Csmith tests. In a separate compiler world generated with GLM 5.2, development continued after repeated agent replacement while retaining full test performance. Genesis also reimplemented 13 MESA modules with over 100k Fortran lines as a Rust workspace with nearly 90k Rust lines; across six numerical workloads, it achieved median speedups of 1.55--6.87x. These results show that long-horizon software development can be organized around a persistent project rather than a persistent agent.
