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. | 1M | 256k |
| 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. | $0.40 | $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. | $2.40 | $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 |
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. | $0.26Alibaba | — |
Cheapest outputLowest output rate across every provider on OpenRouter, the lab included. May come from a different provider than the cheapest input. | $1.56Alibaba | — |

Qwen3.5-Plus and Grok Code Fast 1 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 input: $0.40 vs $1.00 per million tokens. Grok Code Fast 1 is cheaper on output: $2.00 vs $2.40 per million tokens. Figures are base-tier rates. Grok Code Fast 1 shipped 172 days before Qwen3.5-Plus, so benchmark comparisons should account for the intervening progress.
Context windows are 1M (Qwen3.5-Plus) vs 256k (Grok Code Fast 1).
Direct benchmark comparisons are unavailable — Qwen3.5-Plus and Grok Code Fast 1 don't publish scores on any of the same benchmarks.
