bootgpt runs a tiny language model in the boot sector
What happened
A Show HN project called bootgpt appeared on the Hacker News front page on October 31. The developer wrote a 512-byte master boot record in assembly, which loads an 11.5 KB int8 model and runs it in 16-bit real mode on a 386, with no operating system or C runtime. The model has an 8-character context and one hidden layer. After boot it generates a fake Linux boot log with timestamps, PCI addresses and ACPI events. The weights, strings and vocabulary sit in the next 23 sectors, and the Python training script matches the assembly inference character for character.

有人用 512 字节手写汇编 MBR 加载 11.5 KB int8 模型，在 386 的 16 位实模式下运行，无需操作系统和 C 运行时。模型仅有 8 字符上下文和一层隐藏层，启动后会"梦见"一段并不存在的 Linux 启动日志，包含时间戳、PCI 地址和 ACPI 事件。权重、字符串和词表存放在后续 23 个扇区，Python 训练脚本与汇编推理逐字符对齐。
