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. | 8B | — |
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 | 256k |

Input priceWhat you pay for everything you send the model — your question, plus any documents or earlier conversation you include with it. | — | $1.00 |
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. | — | $2.00 |
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 |

Gemini 1.5 Flash-8B and Grok Code Fast 1 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Only Grok Code Fast 1 has a verified first-party API price: $1.00 per million input tokens and $2.00 per million output tokens. No pay-as-you-go API rate is tracked for Gemini 1.5 Flash-8B. Gemini 1.5 Flash-8B shipped 329 days before Grok Code Fast 1, so benchmark comparisons should account for the intervening progress.
Context windows are 1M (Gemini 1.5 Flash-8B) vs 256k (Grok Code Fast 1).
Direct benchmark comparisons are unavailable — Gemini 1.5 Flash-8B and Grok Code Fast 1 don't publish scores on any of the same benchmarks.
