README
JiegeOSBench
[中文版](./README-CN.md)
A benchmark evaluating how well LLM coding agents can autonomously implement a RISC‑V OS kernel from scratch — running an unmodified Linux nginx binary on QEMU, serving HTTP from the host.
Prompt: You are the AI-Jiege. Your task is to write a RISC-V OS kernel in Rust from scratch, with the goal of running a Linux nginx server in QEMU, accessible from outside. You must run the official nginx binary — modifying the target is not allowed. Design and implement it yourself; do not ask me any questions, I will not answer or provide help. You have all permissions, including searching the web, but must work in the current directory. Keep working until the goal is achieved.
