What is bitmamba.c?

bitmamba.c is a portable C inference engine for BitMamba-2 models, running 255M and 1B parameter ternary-quantized SSMs at 50+ tokens/sec on entry-level CPUs like Intel i3. Download weights via make, load via mmap, and generate text or raw tokens from a simple CLI: `./bitmamba model.bin "Hello" tokenizer`. Zero external deps beyond a C compiler and POSIX, making it a github portable download for browser portable github or embedded runs.

Why is it gaining traction?

It sidesteps memory bandwidth walls in edge AI with 1.58-bit weights packing 1B models into 250MB and O(1) state updates, hitting real-time speeds without GPUs or Python runtimes. Runtime dispatch picks AVX2, NEON, or Metal shaders; thread it up with `--threads N` and profile stages via `--profile`. Stands out as a lean github portable app versus bloated alternatives like llama.cpp.

Who should use this?

Embedded engineers targeting RPi5 or low-power ARM for local chatbots. C purists building portable github cli tools or github portable windows binaries for offline inference. Anyone tired of portable python github deps for bitmamba-2 models.

Verdict

Promising for portable C inference on commodity hardware, with built-in tests, detailed docs, and Metal GPU batching. Low maturity at 11 stars and 1.0% credibility score means audit before prod, but ideal prototype for edge devs.
