How GPT-5.4 and Qwen-Long differ
What the numbers mean in practice when choosing between GPT-5.4 and Qwen-Long.
-
Qwen-Long is 97% cheaper on input tokens ($0.072 vs $2.5 per million), which adds up quickly in document-heavy workloads.
-
Qwen-Long is 98% cheaper on output tokens ($0.287 vs $15 per million) - the bigger factor for tools that generate long documents.
-
Qwen-Long's 10M tokens context window is roughly 9.5x larger than GPT-5.4's 1.05M tokens, so it can work across bigger codebases, contracts, or archives in one pass.
Strengths side by side

FAQs
Qwen-Long is generally cheaper: $0.072 input / $0.287 output per million tokens, versus $2.5 / $15 for GPT-5.4. Actual cost depends on how many tokens your workload reads and writes.
Qwen-Long has the larger context window at 10M tokens, compared to 1.05M tokens for GPT-5.4. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
