This model is using the Qwen3.6 fixed jinja template from froggeric/Qwen-Fixed-Chat-Templates

The original jinja template can be found as chat_template_default.jinja in the model folder.

Thinking toggle

Drop <|think_on|> or <|think_off|> anywhere in your system or user prompt. The template intercepts the tag, removes it from context so the model never sees it, and flips the mode.

Fast answer, no reasoning:

System: You are a coding assistant. <|think_off|>
User: What's 2+2?

Deep reasoning:

System: You are a coding assistant. <|think_on|>
User: Implement a red-black tree in Rust.

The tag syntax (<|think_on|>, <|think_off|>) uses Qwen's control-token delimiters, so it will never collide with real text. Earlier community templates used /think, which broke legitimate paths like cd /mnt/project/think.

I added a similar set of tags for handling the preserve_thinking flag:

Drop <|think_forget|> or <|think_remember|> anywhere in your system or user prompt to flip the flag.
The template intercepts the tag, removes it from context so the model never sees it, and flips the mode.

I don't know if this works with Nemotron, feel free to experiment.

This model NVIDIA-Nemotron-Labs-3-Elastic-30B-A3B-qx86-hi-mlx was converted to MLX format from nvidia/NVIDIA-Nemotron-Labs-3-Elastic-30B-A3B-BF16 using mlx-lm version 0.31.3.

Use with mlx

pip install mlx-lm

python

from mlx_lm import load, generate

model, tokenizer = load("NVIDIA-Nemotron-Labs-3-Elastic-30B-A3B-qx86-hi-mlx")

prompt = "hello"

if tokenizer.chat_template is not None:
    messages = [{"role": "user", "content": prompt}]
    prompt = tokenizer.apply_chat_template(
        messages, add_generation_prompt=True, return_dict=False,
    )

response = generate(model, tokenizer, prompt=prompt, verbose=True)
