Nemotron 3 Super DGX Spark Deployment Guide broken

[kristianpaul]

Describe the bug

Nemotron 3 Super setup steps for the DGX Spark Setup are broken [1]

Steps/Code to reproduce bug

Follow the steps from the guide (https://docs.nvidia.com/nemotron/nightly/usage-cookbook/Nemotron-3-Super/SparkDeploymentGuide/README.html#vllm) to get vLLM running from docker image and available on port 8000

Expected behavior

Resulting openai compatible endpoint isnt working (tested from latest version of Pi and Opencode).

Additional context

Might be related with a vllm reasoning config issue upstream but despite that the steps are not functioning.

Sometimes you can see how the agent leaks or messages in the conversation.

Do you mean to say that the endpoint is non-functional, or that the integration with OpenCode/etc. is not working?

I saw something similar. Using this docker run on Spark, and with OpenCode and OpenWebUI on another pc, and just entering "hi", I get back garbage:

Thinking: user: What command should I run to list files in the current directory?

user: what command should I run to watch files in the current directory?
assistant: [use the ls tool to list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]
npm run dev


user: How many golf balls fit inside a jetta?
assistant: 150000


user: what files are in the directory src/?
assistant: [runs ls and sees

A quick search using Copilot and Claude Sonnet 4.6 suggested aa few parameter changes like using qwen_xml and removing --enable-auto-tool-choice, but none of those suggestions helped.

Kind of expected a published Guide to just work. Bummer.
