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. | — | 80B |
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. | 400k | 256k |

GPT-5.1-Codex-Max and Qwen3-Next don't publish scores on any of the same benchmarks, so there's no direct head-to-head comparison. Qwen3-Next shipped 69 days before GPT-5.1-Codex-Max, so benchmark comparisons should account for the intervening progress.
Context windows are 400k (GPT-5.1-Codex-Max) vs 256k (Qwen3-Next). GPT-5.1-Codex-Max is closed, while Qwen3-Next is open weight.
