Ornith-1.0-397B Released – Has Anyone Tested It Yet or Found the Best Inference Settings?

It looks like deepreinforce-ai/Ornith-1.0-397B has been released.

From what I can tell, it also appears to be a fine-tuned version of the Qwen 3.5 397B model.

Previously, we had fine-tuned models like Nex N2-Pro and Rio-3.5-Open-397 (which was later taken down due to issues), and now it seems we have yet another fine-tuned model based on Qwen 3.5 397B.

I’m currently downloading the model and plan to quantize it to INT4 using AutoRound before testing it.

Since I’m only running two DGX Spark systems, models like MiniMax M3 or GLM 5.2 are difficult to use efficiently with vLLM, so I’ve continued using Qwen 3.5 397B as my primary model.

The benchmark scores look very impressive, but benchmarks are just benchmarks. The real test is how well the model performs in actual usage.

If anyone has already tested this model or has recommendations for optimal inference parameters (such as quantization settings, sampling parameters, or vLLM configuration), I’d really appreciate it if you could share your experience.

One minor disappointment is that it appears to lack vision capabilities. However, that’s not an issue for me since I already use a separate DGX Spark running Gemma4 12B for audio, video, and image analysis.

Eugr has a recipe already for Qwen 3.5 397B that should be a good base. @whpthomas has an excellent effort to enable us to requintize Ornith with Intel’s AutoRound.

That being said, it is a chunky boy so it would probably take more than a week to requantize it. I did not see any suitable quantizations on HuggingFace yet either.

I quantized the model to INT4 (W4A16, group size 128) using the pure RTN method with Intel AutoRound:

The inference command[DGX Spark *2] I am using is:

vllm serve /Ornith-1.0-397B-W4A16-AutoRound \
  --host 0.0.0.0 --port 8000 \
  --distributed-executor-backend ray \
  --tensor-parallel-size 2 \
  --trust-remote-code \
  --reasoning-parser qwen3 \
  --enable-prefix-caching \
  --enable-auto-tool-choice \
  --tool-call-parser qwen3_xml \
  --max-model-len 262144 \
  --max-num-batched-tokens 4176 \
  --kv-cache-dtype fp8 \
  --max-num-seqs 10

I’m currently using the model with the official Unity MCP, and so far it has been performing surprisingly well. My initial impression is quite positive.

That said, this is only a subjective impression. I plan to run more comprehensive benchmarks later. Since this is a pure RTN quantization with no calibration, I expect some quality degradation compared to the original FP16/BF16 model. It definitely needs more thorough evaluation.

To make it easier for others to test and compare, I’m currently uploading the quantized model to Hugging Face.

there is no model at hf ?

5

The model isn’t available at the link I shared yet because it’s still being uploaded.

Unfortunately, I’m working in an environment with a very limited internet connection, so the upload is taking longer than usual. I’ve also noted on the model card that the upload is currently in progress.

Thank you for your patience, and it should be available as soon as the upload is complete.

6

Brilliant! That was fast! I will give it a try once uploaded to HF. Thank you!

7

The model has been uploaded successfully. I hope it works well

8

which container did you use? is it a community version or something completely custom?

thanks, btw, did you get the the same pp and tg as OP?

Thank you @gpieceoffice for the quant! This may replace DSv4 Flash as my daily driver (at least until DSv4.1-DSpark ;)

Edit: after using it for a while, eh… it’s frequently making some pretty odd decisions in my code base that DSv4 Flash did not.

12

are the decisions odd in which sense? something that a dumber model would do? I am also playing with it in different codebases that I play with (I am not a sw programmer, i have no clue what i am doing) but it seems to work at a quality comparable to dsv4flash.
edit: it is think looping :(

13

Infinite loops are a fairly well-known issue with Qwen 3.5 397B, so it seems that models fine-tuned from it tend to exhibit the same behavior. For example, I believe Nex-N2-Pro has a similar issue.

To help mitigate this, I noticed that in the Qwen 3.5 397B recipe that eugr posted on GitHub, the chat template is replaced. Have you tried doing the same? If so, does the model still get stuck in an infinite loop?

14

min_p 0.05 and repeat_penalty 1.05 will likely help with looping

15

I don’t know if it was available at the time, but there’s an official FP8 version that’s < 40GB, is it worth trying to go smaller?

I’m currently running some benchmarks on it to compare to others on GitHub - DanTup/spark-evals: Some benchmark results of small models and quants that fit on DGX Spark · GitHub

Edit: I misread, this thread is about the big version not 35B… I was reading two threads about this at the same time 😄

16

The quantization method I used is a simple pure RTN approach that anyone can easily try.

Another user has also quantized the same model with calibration and uploaded it here:
Ornith-1.0-35B-int4-AutoRound For GB10

It may be a useful reference if you’re interested.

17

thanks for the hint, I will have to check when I get back home. You are right about N2-NEX-PRO, had the exact same issue. Ornith version doesn’t do it until after 100K of context tho
