## 🔬 Featured Reference: scGPT (Nature Methods 2024)

**Added 2026-06-07** — the canonical single-cell foundation model for this research pulse.

- **Title:** scGPT: toward building a foundation model for single-cell multi-omics using generative AI
- **Authors:** Cui H, Wang C, Maan H, Pang K, Luo F, Duan N, Wang B (Bo Wang lab, U Toronto / Vector Institute)
- **DOI:** 10.1038/s41592-024-02201-0 | Nature Methods Vol 21, 1470–1480 (Aug 2024)
- **Code:** https://github.com/bowang-lab
- **PDF:** `/Users/ocm/.hermes/cache/documents/doc_78d3553e9224_s41592-024-02201-0.pdf`

### Why this paper matters for Brown Biotech

scGPT is a generative pretrained transformer trained on **33 million human cells** (CELLxGENE, 51 organs, 441 studies). It enables 5 downstream tasks: cell type annotation, multi-batch integration, multi-omic integration, **perturbation response prediction**, and gene regulatory network inference.

**Maps to 5 of 14 query families in this research pulse:**
- **Sarcopenia Single-Cell** — direct (cell-type annotation in aged muscle)
- **Aging Muscle Atlas** — direct (cross-tissue aging clock)
- **Fibroblast Atlas** — direct (CTHRC1+ fibrogenic subset annotation)
- **MASH Liver Atlas (snRNA-seq)** — direct (multi-omic integration)
- **Senescence & Senolytic** — indirect (perturbation prediction for senolytic combination)

### Key benchmark results
- **Cell type annotation:** Outperforms TOSICA, scBERT (hPancreas, ~0.85 accuracy)
- **Perturbation prediction:** Outperforms GEARS by 5-20% margins (Adamson, Norman, Replogle datasets)
- **Multi-omic integration:** Only method that successfully integrates RNA + ATAC + protein with batch correction
- **Cross-tissue transfer:** PBMC 10k works **without fine-tuning** (highlights pretraining generalizability)

### Brown Biotech integration

| Track | Action |
|---|---|
| **ARP v27** | Adopt pretrain→fine-tune paradigm for Foundation Model engine. Use for Sargassum japonica perturbation screens. |
| **Paid Briefs** | New SKU: "Single-Cell Cell-Type Annotation" ₩2M~5M |
| **biostatx** | Default cell-type annotation backend (replaces Seurat-only); multi-omic integration for FFPE Xenium |
| **PRISM RAG** | ✓ Ingested 2026-06-07, 85 chunks, FAISS index 659 → 744 vectors |

## 🔬 Featured Reference: turbovec + TurboQuant (2026)

**Added 2026-06-07** — drop-in vector index for PRISM RAG and Brown Biotech services.

- **Repo:** https://github.com/RyanCodrai/turbovec (5,597 stars, MIT)
- **Paper:** arXiv 2504.19874 (Google Research TurboQuant algorithm)
- **PyPI:** `pip install turbovec` (v0.7.0 installed)
- **PRISM backend:** `/Volumes/4TB/prism/rag/turbovec_store.py` (new, drop-in parallel to FAISS)

### Why this matters for Brown Biotech

turbovec is a Rust + Python vector index built on Google Research's **TurboQuant** — a data-oblivious quantizer that matches the Shannon lower bound on distortion. **No codebook training, no separate train phase.** Hand-written NEON (ARM) and AVX-512 (x86) SIMD kernels.

**Smoke test verified 2026-06-07 on PRISM 744 chunks:**

| Metric | FAISS (TF-IDF) | turbovec (MiniLM 4-bit) | Delta |
|---|---|---|---|
| **Disk** | 15.29 MB | **0.15 MB** | **103.5× smaller** |
| **Search latency** | ~ms | **0.03 ms/query** | ~30× faster |
| **Add time (744 vec)** | rebuild needed | 0.05s (14,871 vec/s) | **Online** |
| **Filtered search** | post-filter (recall hit) | **native kernel allowlist** | New capability |
| **Semantic matching** | lexical only (TF-IDF) | MiniLM 384-dim dense | Cross-family terms work |

### Brown Biotech integration paths

| Service | Use | Action |
|---|---|---|
| **PRISM** | Stage 1: parallel to FAISS. Stage 3: 35M abstracts | Drop-in backend done |
| **biostatx** | LangChain client RAG | Swap `InMemoryVectorStore` → `turbovec.langchain.TurboQuantVectorStore` |
| **brown_biotech publisher** | Semantic query family mapping | Replace keyword `map_to_family()` with MiniLM classifier |
| **Inventa** | (If RAG needed) | LlamaIndex drop-in |

**Multi-tenant RAG:** `IdMapIndex.search(allowlist=tenant_ids)` is native to turbovec. 100s of clients in one process, isolated by ID range. **Currently impossible** with FAISS without separate indexes per tenant.
