Forward pass (RESEARCH — multi-week) - -The hard part. BERT-small has: - * 12 transformer layers - * Hidden size 512, attention heads 8 - * ~30M params total - -Each forward pass is: - 1. Embedding lookup (ids → 512-dim vectors) - 2. Positional encoding add - 3. 12 × (self-attention + FFN + LayerNorm) - 4. Pooler (CLS token projection) - 5. Classifier head (2-way sigmoid) - -Hot path is the 12 matmuls per transformer layer. Each is ~512×512×{seq_len}. -At seq_len=128 that's ~100 matmuls of shape (128, 512) @ (512, 512). - -**Two viable approaches:** - -**Approach A: Pure-TS with Float32Array + SIMD** - * Use Bun's typed array support + SIMD intrinsics (when they land in - Bun stable — currently wasm-only) - * Implementation: ~2000 LOC of careful numerics. LayerNorm, GELU, - softmax, scaled dot-product attention all hand-written. - * Latency estimate: ~30-50ms on M-series (meaningfully slower than - WASM which uses WebAssembly SIMD) - * VERDICT: not worth it standalone. Pure-TS can't beat WASM at matmul. - -**Approach B: Bun FFI + Apple Accelerate** - * Use `bun:ffi` to call Apple's Accelerate framework (cblas_sgemm). - On M-series, cblas_sgemm for 768×768 matmul is ~0.5ms. - * Weights stored as Float32Array (loaded from ONNX initializer tensors - at startup), tokenizer in TS, matmul via FFI, activations in pure TS. - * Implementation: ~1000 LOC. The numerics are the same, but the bulk - work is offloaded to BLAS. - * Latency estimate: 3-6ms p50 (meets target). - * RISK: macOS-only. Linux would need OpenBLAS via FFI (different - symbol layout). Windows is a whole separate story. - * VERDICT: viable for macOS-first gstack. Matches our existing ship - posture (compiled binaries only for Darwin arm64). - -**Approach C: WebGPU in Bun** - * Bun gained WebGPU support in 1.1.x. transformers.js already has a - WebGPU backend. Could we route native Bun through it? - * RISK: WebGPU in headless server context on macOS requires a proper - display context. Unclear if it works from a compiled bun binary. - * STATUS: unexplored.

Weight loading (EASY — shipped) - -ONNX initializer tensors can be extracted once at build time into a -flat binary blob that `bun:ffi` can `mmap()`. Net result: zero -decompression at runtime.

Confirm <1ms latency. - -3. **Single transformer layer in FFI** — call cblas_sgemm for Q/K/V - projections, implement LayerNorm + softmax in TS. Compare output - against onnxruntime on the same input_ids. Must match within 1e-4 - absolute error. - -4. **Full forward pass** — wire all 12 layers + pooler + classifier. - Correctness against onnxruntime across 100 fixture strings. - -5. **Production swap** — replace the `classify()` body in - security-bunnative.ts. Delete the WASM fallback. - -6. **Quantization** — int8 matmul via Accelerate's cblas_sgemv_u8s8 - (if available) or fall back to onnxruntime-extensions. ~50% memory - reduction, marginal speed win. - -## Why not just ship this in v1? - -Correctness is the issue.

Optimization opportunities: - - Float16 quantization (halves memory, faster on ARM) - - KV cache for repeated prefixes - - Batch tokenization for page content - - Skip layers for high-confidence early exits - - Bun's FFI for BLAS matmul (Apple Accelerate on macOS) -``` - -**Effort:** XL (human: ~2 months / CC: ~1-2 weeks) - -**Why this might be worth it:** -- 5ms inference means we can scan EVERYTHING: every message, every page, every tool - output, every browse command response.

Works everywhere Bun works. -- gstack becomes the only open source tool with native-speed prompt injection detection. -- The tokenizer + inference engine could be published as a standalone package. - -**Why it might not:** -- WASM at 50-100ms is probably good enough for the sidebar use case. -- Maintaining a custom inference engine is a lot of ongoing work. -- @huggingface/transformers will keep getting faster (WebGPU support is already landing). -- The 5ms target matters more if we're scanning every tool output, which we're not doing yet. - -**Recommended path:** -1.
