Nemotron vs Llama: Open Model Comparison

NVIDIA's Nemotron and Meta's Llama 4 are both open-weight model families available on unoblox, but only one of them has a fixed ₹ rate in the current price list. Here's what's actually known and priced today.

What the model ids tell you

nvidia/nemotron-3-ultra-550b-a55b and meta-llama/llama-4-scout-17b-16e-instruct both encode architecture details in their names — a common convention where the first number is total parameters and a suffix like "a55b" or the expert count points to a mixture-of-experts design with a smaller active-parameter count per token. Treat that as a naming convention, not a performance claim — the only way to know how a model behaves on your workload is to test it directly.

₹ pricing: what's fixed and what isn't

Model	Model id	Input (₹ / 1M tokens)	Output (₹ / 1M tokens)
Nemotron 3 Ultra	nvidia/nemotron-3-ultra-550b-a55b	₹50.61	₹222.70
Llama 4 Scout	meta-llama/llama-4-scout-17b-16e-instruct	₹10.12	₹30.36

Rates are as of 6 October 2026; check each live model page (for example https://unoblox.ai/models/nvidia/nemotron-3-ultra-550b-a55b) before estimating cost for a production workload. Llama 4 Maverick is not currently offered on unoblox.

Choosing between a large MoE model and Llama 4

• If your priority is a known, fixed ₹ cost you can budget against today, Llama 4 Scout is the cheaper starting point.
• If you specifically want to evaluate Nemotron's larger architecture for a demanding task, test it first at low volume and confirm its live rate before scaling up — don't assume it's priced similarly to Llama.
• For most general-purpose text tasks, start with the cheaper Llama 4 Scout and only move to a larger model if your evaluation shows a real quality gap on your own prompts.

Same request shape for both families

  -d '{"model":"meta-llama/llama-4-scout-17b-16e-instruct","messages":[{"role":"user","content":"Summarise this report in three bullet points."}]}'

Change "model" to nvidia/nemotron-3-ultra-550b-a55b to test the same prompt on Nemotron — same key, same endpoint, one GST invoice covering both.

Frequently asked questions

Is Nemotron cheaper or more expensive than Llama 4? Nemotron 3 Ultra (₹50.61 / ₹222.70) costs more than Llama 4 Scout (₹10.12 / ₹30.36) on both input and output tokens.

What does the "550b-a55b" naming mean? It's a common shorthand for a mixture-of-experts model's total parameter count versus its active parameters per token — a naming convention, not a guarantee of relative quality against Llama.

Are Nemotron and Llama hosted on infrastructure in India? No, both run on their standard hosting behind unoblox's endpoint. The India benefit is ₹ billing, a GST invoice and one endpoint — not data residency for these models.

Which Llama 4 model should I start with? Llama 4 Scout — it is the Llama 4 model offered on unoblox and a reasonable low-cost baseline.

Can I test Nemotron without committing to production volume? Yes — call it like any other model with your existing key at low volume, and confirm the live ₹ rate before scaling.

Do open-weight models like these get updated over time? Providers do update model versions; always check the model's live page for the current id and rate rather than assuming past pricing still applies.
