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. | — | 397B |
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. | 1.05M | 1M |
| API pricingUSD per 1M tokens · lower wins · base tier | ||
Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it. | $30.00 | $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. | $180.00 | $2.40 |
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. | $15.00OpenAI | $0.26Alibaba |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | $90.00OpenAI | $1.56Alibaba |

GPT-5.4-Pro and Qwen3.5-Plus don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Qwen3.5-Plus is cheaper on both input and output: $0.40 vs $30.00 per million input tokens, and $2.40 vs $180.00 per million output tokens. Figures are base-tier rates. Qwen3.5-Plus shipped 17 days before GPT-5.4-Pro, so benchmark comparisons should account for the intervening progress.
Context windows are 1.05M (GPT-5.4-Pro) vs 1M (Qwen3.5-Plus).
Direct benchmark comparisons are unavailable — GPT-5.4-Pro and Qwen3.5-Plus don't publish scores on any of the same benchmarks.
