Specifications
Context windowHow much text the model can hold in mind at once — your question, any documents you attach, the conversation so far, and its own reply. Go past it and the earliest part falls out of view.

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.
—$2.00
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.
—$10.00
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.
—$0.10
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.

Frequently asked questions

Gemini 3.8 Flash Cyber and GPT-6.1 Sol don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only GPT-6.1 Sol has a verified first-party API price: $2.00 per million input tokens and $10.00 per million output tokens. No pay-as-you-go API rate is tracked for Gemini 3.8 Flash Cyber. Gemini 3.8 Flash Cyber shipped 27 days before GPT-6.1 Sol, so benchmark comparisons should account for the intervening progress.

Published specifications for these two models are limited — see each model page for the latest details.
