Use Nemotron 3 Super with automatic failover

A single free tier runs out. Ficelle puts the free models of every provider you configure behind one local OpenAI-compatible endpoint. Call a routing profile and Nemotron 3 Super is one of the models it can pick; when it rate-limits or fails, the next eligible free model answers. To pin Nemotron 3 Super alone, call the id that ficelle models lists for it, knowing a pinned model has no failover.

python
from openai import OpenAI

client = OpenAI(base_url="http://127.0.0.1:8646/v1", api_key="ficelle-local")

# A routing profile keeps failover: Nemotron 3 Super is one of the free
# models it can pick, and the next eligible one answers if it fails.
client.chat.completions.create(
    model="ficelle/auto-orchestrator",
    messages=[{"role": "user", "content": "..."}],
)

Whether a profile routes to Nemotron 3 Super on your install depends on your providers' live catalogs and Ficelle's eligibility checks, decided at request time.

Questions

Is Nemotron 3 Super free to use?

NVIDIA publishes the weights under its open model license, and two providers serve it on a free tier. When we checked on 28 September 2026, Requesty and Cloudflare served it at no charge, each under its own free-tier limits.

Where can I use the Nemotron 3 Super API for free?

Requesty as nvidia/nemotron-3-super-120b-a12b; Cloudflare as @cf/nvidia/nemotron-3-120b-a12b. Free catalogs change often, so check the provider's own page before you rely on one.

What is Nemotron 3 Super?

Nemotron 3 Super is NVIDIA's open 120B mixture-of-experts model with 12B active parameters, a hybrid Mamba and attention design built for multi-agent workflows, long-context reasoning, tool use and RAG.

Can I call Nemotron 3 Super through Ficelle?

Yes, when one of your configured providers serves it for free. Run ficelle models to see the ids your install can route to. Calling that id pins the one model, with no failover; calling a routing profile such as ficelle/auto-orchestrator keeps failover, so another free model answers when Nemotron 3 Super is rate-limited.
