II Medical 8B GGUF
GGUF quantizations of Intelligent-Internet/II-Medical-8B, verified end-to-end on the NVIDIA DGX Spark (GB10, 128 GB unified memory).

Spark-tested
Every Orionfold quant ships with a measurement quad on the NVIDIA DGX Spark (GB10, 128 GB unified memory): perplexity, sustained tok/s, thermal envelope, and MedMCQA (n=50, mcq_letter) accuracy. The numbers below are the actual run, not a wishlist.
| Variant | Size | Perplexity (wikitext-2) | tok/s on Spark | MedMCQA (n=50, mcq_letter) |
|---|---|---|---|---|
| Q4_K_M | 4.7 GB | 16.550 | 43.6 | 42.0% |
| Q5_K_M | 5.4 GB | 16.242 | 36.4 | 52.0% |
| Q6_K | 6.3 GB | 16.014 | 32.8 | 46.0% |
| Q8_0 | 8.1 GB | 16.296 | 28.4 | 48.0% |
| F16 | 15.3 GB | 16.268 | 15.9 | 48.0% |
Thermal envelope: sustained-load minutes before thermal throttle on a single GB10 = 18 min. Beyond this, expect tok/s degradation; the duty-cycle disclosure is per Orionfold's quant-card standard.
Variants
| Variant | Recommended use |
|---|---|
| Q4_K_M | Best balance — fits comfortably in Spark unified memory at 70B; default pick. |
| Q5_K_M | Higher quality than Q4_K_M with modest size bump. |
| Q6_K | Near-lossless; recommended if memory headroom allows. |
| Q8_0 | Effectively lossless; reach for this when quality matters more than throughput. |
| F16 | Reference — no quantization. Use only for measurement / baseline. |
How to run
Pull a variant:
huggingface-cli download Orionfold/II-Medical-8B-GGUF model-Q5_K_M.gguf \
--local-dir ./models/ii-medical-8b
Serve it via llama-server (OpenAI-compatible API):
llama-server -m ./models/ii-medical-8b/model-Q5_K_M.gguf \
-c 4096 -ngl 99 -t 8 \
--host 0.0.0.0 --port 8080
Or run in-process via llama-cpp-python:
from llama_cpp import Llama
llm = Llama(
model_path="./models/ii-medical-8b/model-Q5_K_M.gguf",
n_ctx=4096, n_gpu_layers=99, chat_format="chatml",
)
out = llm.create_chat_completion(
messages=[{"role": "user", "content": "Summarize the key idea in one paragraph."}],
temperature=0.0,
)
print(out["choices"][0]["message"]["content"])
LM Studio and Ollama (via a Modelfile) load the GGUF directly with no additional setup.
Methods
Full methodology and Spark-side measurement protocol: Vertical-curator quants on Spark — II-Medical-8B-GGUF + MedMCQA mini-eval.
Other Orionfold vertical curators
Same Spark-tested recipe across the curator-on-Spark series:
- finance-chat-GGUF — AdaptLLM finance-chat (Llama-2-7B lineage) for FinanceBench-shaped queries
- Saul-7B-Instruct-v1-GGUF — Equall Saul-7B legal-instruct for LegalBench-shaped queries
- SecurityLLM-GGUF — Mistral-based cyber-tuned model with CyberMetric mini-eval gating
Each card lists its own measurement quad; the headline numbers are recorded as the actual sweep ran, never pre-corrected.
