Models & API
Live view of what the DGX Spark cluster is serving and how to call it — the model list below is fetched live on every page load.
How to connect
The gateway is OpenAI-compatible. Point any OpenAI SDK at it with the API key issued from your Dashboard.
| Base URL | http://192.168.1.199:14000/v1 |

| Endpoints | /chat/completions · /completions · /embeddings · /models |
| Features | streaming ("stream":true), tool/function calling, vision (image_url) |
Primary models
Always-on GPU lanes (live status). Fastest first token.
qwen3.5-122b-a10b
● live
gemma4-26b-fp8
● live
qwen3-coder-30b-fp8
● live
qwen3-vl-235b-awq
on-demand
○ down
On-demand models (e.g. qwen3-vl-235b-awq) are spun up when needed and are otherwise down — a call returns an error until an operator brings them up.
Examples
Python (OpenAI SDK)
from openai import OpenAI
client = OpenAI(base_url="http://192.168.1.199:14000/v1", api_key="YOUR_KEY")
r = client.chat.completions.create(
model="qwen3-coder-30b-fp8",
messages=[{"role": "user", "content": "Write a haiku about GPUs."}],
)
print(r.choices[0].message.content)
curl
curl http://192.168.1.199:14000/v1/chat/completions \
-H "Authorization: Bearer YOUR_KEY" \
-H "Content-Type: application/json" \
-d '{"model":"gemma4-26b-fp8","messages":[{"role":"user","content":"hello"}]}'
Vision — qwen3-vl-235b-awq (on-demand)
client.chat.completions.create(model="qwen3-vl-235b-awq", messages=[{"role":"user","content":[
{"type":"image_url","image_url":{"url":"data:image/png;base64,..."}},
{"type":"text","text":"What is in this image?"}]}])
All models on the gateway (36)
Everything callable with your key. Non-primary models are Ollama-backed and load on demand (slower first token). Embeddings: embeddinggemma, bge-m3.

Advanced — Anthropic-format router
For Claude Code / Anthropic-format clients, the router at http://192.168.1.199:14100 speaks the Anthropic Messages API (/v1/messages) for the primary models. Reachable on the LAN without a key.
