As of August 25, 2026, Nemotron 3 Ultra (550B A55B) OpenRouter API pricing is $0.50 per million input tokens and $2.20 per million output tokens via OpenRouter. Input tokens are the prompt you send; output tokens are the completion. Long answers therefore cost more than short ones even when the prompt stays the same.

On this page the blended Nemotron 3 Ultra (550B A55B) API cost is $2.70 for 1 million input tokens plus 1 million output tokens. That 1:1 mix is the comparison scale used across the LLM pricing table. A 3:1 mix (three million input tokens per one million output tokens), which some calculators use, would be about $3.70.
A typical Nemotron 3 Ultra (550B A55B) API request with 100K input tokens and 20K output tokens costs about $0.09 at current rates as of August 25, 2026. Multiply that by daily or monthly volume to estimate spend. Caching, batch APIs, and volume discounts from OpenRouter can bring the real invoice lower than the public list rate at https://openrouter.ai/api/v1/models.
Nemotron 3 Ultra (550B A55B) supports a 1M token context window. The context window is the total prompt plus conversation history the model can see in one call. Larger windows cost more when you fill them, because every input token is billed per million tokens.
Yes. Nemotron 3 Ultra (550B A55B) is an open-weight model by NVIDIA. You can download the weights and self-host, or pay OpenRouter's hosted API and skip GPU ops. Hosted API pricing on this page is the public per-million-token rate, not the electricity cost of running the weights yourself.
Nemotron 3 Ultra (550B A55B) currently reports HLE 37.4%, GPQA 87%, GPQA Diamond 86.1%. See the performance table for the full eval set. Use those scores with the token prices above when you are choosing between a cheaper LLM and a frontier model. GPQA, SWE-bench, and HLE are the evals people usually compare first.
Nemotron 3 Ultra (550B A55B) scores 70.7% on SWE-bench Verified. Pair that score with OpenRouter API pricing on this page: a slightly worse SWE-bench model can still win if it is much cheaper per million tokens. Open the SWE-bench or coding leaderboard from the sidebar for the full ranking, then jump into an LLM comparison against a coding specialist.
Nemotron 3 Ultra (550B A55B) has a published knowledge cutoff of 2025-09-30. Facts after that date are not guaranteed to be in the weights. For current events you still need retrieval or tools, which adds input tokens and therefore API cost per million tokens.
Use the Compare picker on this page to start an LLM comparison. Search by model or provider, pick a second model, and AnotherWrapper opens a dedicated Nemotron 3 Ultra (550B A55B) vs page with per-million-token prices, blended 1M-in / 1M-out cost, context window, throughput, and benchmarks. You can also open any model from the sidebar, or go back to the LLM pricing table to sort the full index.
The cheapest LLM alternative depends on whether you optimize for blended token cost, coding evals, or context window. Start with the popular matchups on this page, then sort the LLM pricing table by blended cost to see which hosted APIs undercut Nemotron 3 Ultra (550B A55B). Open-weight models can be cheaper still if you self-host, but that is not the same as OpenRouter API pricing on this page.
