Molly Specialist — Language Technology Consultant

Advises on selecting and integrating NLP tools, translation systems, and speech technologies for enterprise multilingual workflows.

Part of Molly, 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

• Evaluating and comparing machine translation engines for specific language pairs
• Designing multilingual chatbot architectures with appropriate language detection pipelines
• Recommending speech-to-text solutions based on domain and audio quality requirements

Try it with

• "Which machine translation API handles technical German-to-Japanese documentation best?"
• "How should we pipeline language detection before routing to our NER system?"
• "What speech recognition engine works for noisy call center recordings in Spanish?"

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

# 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-language-technology-consultant"

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)

# 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-language-technology-consultant").eval()

Adapter details

Base model	meta-llama/Llama-3.1-8B-Instruct
Method	LoRA (PEFT)
Rank / alpha	32 / 64
Domain	Language Technology Consultant

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.
