ParametersThe learned values that shape how a model responds. B means billion and T means trillion. For mixture-of-experts models, the total count is larger than the number active for each token. Parameter count alone does not measure quality. | 340B | — |
Context windowHow much information the model can work with in one request, measured in tokens — pieces of words or other data. This includes your question, attachments, conversation and reply. Limits can vary by model variant and provider. | 4k | 1M |
| API pricingUSD per 1M tokens · lower wins | ||
Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it. | — | $0.40 |
Output priceWhat you pay for the text the model writes back. It is normally the dearer half: producing an answer costs more than reading one. | — | $1.60 |
Cached input priceA reduced rate for text you send over and over. If every request starts with the same instructions or the same document, the provider keeps a copy ready and charges less to read it again. | — | $0.10 |
Cheapest inputLowest input rate across every provider on OpenRouter, the lab included. The cheapest endpoint may run a quantised build or a shorter context — see "Available from" on the model page. | — | $0.40Azure |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | — | $1.60Azure |

Nemotron-4 340B and GPT-4.1 mini don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only GPT-4.1 mini has a verified first-party API price: $0.40 per million input tokens and $1.60 per million output tokens. No pay-as-you-go API rate is tracked for Nemotron-4 340B. Nemotron-4 340B shipped 304 days before GPT-4.1 mini, so benchmark comparisons should account for the intervening progress.
Context windows are 4k (Nemotron-4 340B) vs 1M (GPT-4.1 mini). Nemotron-4 340B is open weight, while GPT-4.1 mini is closed.
Direct benchmark comparisons are unavailable — Nemotron-4 340B and GPT-4.1 mini don't publish scores on any of the same benchmarks.
