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. | — | 314B |
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. | 200k | 8k |

o4-mini-high and Grok‑1 don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Grok‑1 shipped 530 days before o4-mini-high, so benchmark comparisons should account for the intervening progress.
Context windows are 200k (o4-mini-high) vs 8k (Grok‑1). o4-mini-high is closed, while Grok‑1 is open weight.
