Notes, in order.
1bit.MONSTER is now 1bit engine
1bit.MONSTER grew fast: an inference engine, a model zoo, benchmarks, a store, a voice assistant and a lot of experiments, all in one repository with all of its history. The engine that came out of it is now its own project, 1bit engine, and this site is its home.
Prefill on HRX, decode on Vulkan, one KV cache
On Strix Halo's Radeon iGPU, AMD's HRX runtime prefills a prompt faster than Vulkan, and Vulkan decodes faster than HRX. 1bit serve --device vulkan --prefill-device hrx now uses both on the same request, and the key-value cache never gets copied between them.
The first week of 1bit engine
The clean repository started on 2026-09-22. In its first three days, the engine came up on every device it targets, inside Lemonade, with each step verified on real hardware before it merged. These are the milestones, with the numbers and where they come from.

The posts from before the clean repository, as they were written. They describe the old monorepo; the engine's current numbers are on the wiki.
