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. | 2.8T | — |
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. | 1M | 400k |
| 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. | $4.00 | $12.50 |
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. | $20.00 | $75.00 |
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. | $0.20 | $1.25 |

Kimi K3.1 Pro Highspeed and GPT-5.6 Cyber don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Kimi K3.1 Pro Highspeed is cheaper on both input and output: $4.00 vs $12.50 per million input tokens, and $20.00 vs $75.00 per million output tokens. GPT-5.6 Cyber shipped 74 days before Kimi K3.1 Pro Highspeed, so benchmark comparisons should account for the intervening progress.
Context windows are 1M (Kimi K3.1 Pro Highspeed) vs 400k (GPT-5.6 Cyber).
