-# Molly OS — Specialist Adapter: Polymer Chemist
+# Molly Specialist — Polymer Chemist
+
+Predicts copolymer composition from monomer reactivity ratios, recommends controlled polymerization conditions, and estimates thermal properties of synthesized polymers.
+
+Part of **[Molly](https://iamolly.ai/?utm_source=huggingface&utm_medium=model_card&utm_campaign=specialists&utm_content=molly-polymer-chemist)**, an orchestrator that keeps a library of small domain
+specialists over one quantized base and routes each request to the right one, so a
+single machine answers across many fields without loading a separate large model
+for each.
+
+## What this specialist handles well
+
+- Predicts copolymer composition from monomer reactivity ratios
+- Recommends initiators and conditions for controlled radical polymerization
+- Estimates glass transition and decomposition temperatures for polymers
+
+## Try it with
+
+- "What monomer feed ratio gives a 50/50 copolymer of styrene and methyl methacrylate?"
+- "Which chain transfer agent best controls molecular weight in RAFT polymerization of acrylamides?"
+- "How does tacticity affect the glass transition temperature of poly(methyl methacrylate)?"
+
+## Before you run: the base model is gated
+
+This adapter needs the base weights, and the base is **access-gated**. Do this **once**:
+
+1. Accept the base licence: <https://huggingface.co/meta-llama/Llama-3.1-8B-Instruct>
+2. Create a **read token**: <https://huggingface.co/settings/tokens>
+3. Make the token available:
+   - **Google Colab:** Secrets panel (key icon) → *Add new secret* → name `HF_TOKEN`, enable **Notebook access**.
+   - **Kaggle:** *Add-ons → Secrets* → add `HF_TOKEN`.
+   - **Local:** `huggingface-cli login` or `export HF_TOKEN=...`
+
+Skipping this gives `GatedRepoError` / `401 Unauthorized` when the **base** loads. A stored
+Colab secret is **not** applied automatically — authenticate in code, as below.
+
+## Quickstart
+
+```python
+# pip install -U transformers peft accelerate
+import os, torch
+from huggingface_hub import login
+try:
+    from google.colab import userdata
+    login(userdata.get("HF_TOKEN"))
+except Exception:
+    tok = os.environ.get("HF_TOKEN")
+    login(tok) if tok else login()
+
+from transformers import AutoModelForCausalLM, AutoTokenizer
+from peft import PeftModel
+
+BASE = "meta-llama/Llama-3.1-8B-Instruct"
+ADAPTER = "BoomJules/molly-polymer-chemist"
+
+tok = AutoTokenizer.from_pretrained(BASE)
+base = AutoModelForCausalLM.from_pretrained(BASE, torch_dtype=torch.bfloat16, device_map="auto")
+model = PeftModel.from_pretrained(base, ADAPTER).eval()
+
+msgs = [{"role": "user", "content": "Your question here"}]
+ids = tok.apply_chat_template(msgs, add_generation_prompt=True, return_tensors="pt").to(model.device)
+out = model.generate(ids, max_new_tokens=300)
+print(tok.decode(out[0][ids.shape[1]:], skip_special_tokens=True))
+```
+
+## Low-VRAM (4-bit) — fits a free Colab/Kaggle GPU (~6–7 GB)
+
+```python
+# pip install -U transformers peft accelerate bitsandbytes
+import os, torch
+from huggingface_hub import login
+try:
+    from google.colab import userdata
+    login(userdata.get("HF_TOKEN"))
+except Exception:
+    login(os.environ.get("HF_TOKEN"))
+
+from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
+from peft import PeftModel
+
+bnb = BitsAndBytesConfig(load_in_4bit=True, bnb_4bit_quant_type="nf4",
+                         bnb_4bit_compute_dtype=torch.bfloat16, bnb_4bit_use_double_quant=True)
+tok = AutoTokenizer.from_pretrained("meta-llama/Llama-3.1-8B-Instruct")
+base = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-3.1-8B-Instruct", quantization_config=bnb, device_map="auto")
+model = PeftModel.from_pretrained(base, "BoomJules/molly-polymer-chemist").eval()
+```

+## Adapter details
+
+| | |
+|---|---|
+| Base model | `meta-llama/Llama-3.1-8B-Instruct` |
+| Method | LoRA (PEFT) |
+| Rank / alpha | 32 / 64 |
+| Domain | Polymer Chemist |
+
+## Troubleshooting
+
+- **`GatedRepoError` / `401 Unauthorized`** — base licence not accepted, or `HF_TOKEN` missing,
+  or the Colab secret was stored but `login(...)` was never called.
+- **CUDA out of memory** — use the 4-bit snippet on a GPU runtime.
+- **Adapter seems to have no effect** — confirm the base id matches `base_model` above.
