v0.8: Self-contained inference engine — no external dependencies
TurboQuant is now a COMPLETE inference engine, not just a library.
Loads models, runs forward pass, generates tokens — all in pure C.
New engine components (src/engine/):
- tq_ops.c: matmul (NEON 4-acc unrolled), rmsnorm, rope, silu, softmax
- tq_transformer.c: Full LLaMA-style forward pass with GQA + SwiGLU FFN
KV cache uses TurboQuant quantization (integer attention integrated)
- tq_model.c: safetensors loader (mmap, zero-copy, JSON parser)
- tq_tokenizer.c: BPE tokenizer (encode/decode)
- tq_generate.c: Autoregressive generation with top-p sampling + streaming
- tq_run.c: CLI inference tool
API (include/turboquant/tq_engine.h):
tq_load_model(path) → model
tq_forward(model, state, token, pos) → logits
tq_generate(model, prompt, config, output, size) → tokens generated
Key design:
- Zero external dependencies (libc/libm only)
- KV cache automatically quantized with TurboQuant during inference
- Integer Q4×Q8 attention in the forward pass (2.9-4.8x faster)
- NEON-optimized matmul (16 elements/iteration, 4 accumulators)
- mmap model loading (zero-copy)
- Streaming token output via callback
Tests: 19 suites pass (33 new op tests + 18 existing)
Usage:
tq_run --model model.safetensors --prompt "Hello" --kv-type uniform_4b
