Turns out, no.

PureBee is a complete GPU defined as a software specification — Memory, Engine, Instruction Set, Runtime. It runs Llama 3.2 1B inference at 3.6 tok/sec on a single CPU core. The model answers questions correctly.

What makes it different from llama.cpp or WebLLM:

The WASM compute kernel is constructed byte-by-byte in JavaScript at runtime. No Emscripten. No Rust. No compiler. No build step. The binary that runs the Q4 SIMD matrix math is itself readable JavaScript. Every layer of the stack — including the thing executing the math — is auditable source.

The progression from first principles:

```

Baseline JS 0.08 tok/sec

Typed arrays 0.21 tok/sec

WASM kernels 0.70 tok/sec

Q4 quantization 1.30 tok/sec

SIMD 3.00 tok/sec

Worker threads 3.60 tok/sec

```

45× total. Single CPU core. Zero npm dependencies.

The claim isn't that this is faster than a real GPU. The claim is that a GPU was never the hardware — it was always the math. The hardware is just one way to run the math fast. PureBee is another way. If that's true, it changes where inference can run.

To run:

```

git clone https://github.com/PureBee/purebee

node download.js llama3

node --max-old-space-size=4096 chat-llama3.js

```

Requires Node.js ≥ 20. The heap flag is not optional.

Happy to go deep on the WASM binary construction, the Q4 nibble layout, or the SharedArrayBuffer weight cache that runs a 4.5GB model in 1.8GB of RAM.
