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.
What changed#
A clean repository. The engine lives in 1bit-MONSTER/engine. It holds verified code only, without the development history. Each piece is ported over once it passes its end-to-end test on Strix Halo, and the porting map shows what has moved and what is next.
Apache-2.0. The old repository was GPL-3.0. The engine is Apache-2.0, with a copyright and license notice on every file, enforced in CI, and every third-party project it builds on credited in its NOTICE.
Inside Lemonade, not around it. The old engine vendored its own copy of Lemonade. Now Lemonade is the server you talk to (its catalog, downloads, router and UI), and it runs the engine as one of its backends, through 1bit serve, the same way it runs llama-server.
Upstream, pinned and kept current. The XDNA driver and XRT, AMD's HRX pair, llama.cpp for Vulkan, ZINC, the Linux kernel, Hugging Face tokenizers and the Laya router are each pinned to upstream, and the pins are bumped automatically, so new models and fixes arrive soon after upstream ships them.
What it runs on#
One 1bit serve drives:
- the XDNA 2 NPU, on full ELFs generated in C++;
- HRX and Vulkan on the Radeon iGPU, one llama.cpp build with both;
- ZINC, which also reaches NVIDIA GPUs through CUDA;
- MLX on Apple Silicon.
Measured numbers live on the wiki. The first week of 1bit engine lists what the first three days produced.
The old site#
The 1bit.MONSTER site and its posts stay online in the 1bit.MONSTER archive, and old links land on a page that points at their archived copy. The blog page here lists the old posts worth keeping. 1bit JARVIS, the voice assistant, is not part of the engine for now; it will come back later as its own piece.
