nomic-embed-code — Static Token Vectors

Used in: vendored/nomic/code_vectors.bin, vendored/nomic/code_tokens.txt

Static token embeddings extracted from nomic-embed-code (7B parameter code embedding model, Apache-2.0 license).

Extraction Process

Token vectors are extracted via full inference from the nomic-embed-code model:

1. Load nomic-embed-code (7B, Qwen2.5-Coder-7B base)
2. Filter vocabulary to ~40K code-relevant alphanumeric tokens
3. Per-token inference → 768-dim float vectors
4. Simulated attention (K=32 neighbors, 3 iterations, α=0.3)
5. Mean centering (anisotropy fix)
6. Int8 quantization (×127 scaling) → ~12MB binary blob

The 7B model is NOT bundled or used at runtime — only the pre-computed static vectors are included.
