How GPT-5 and Qwen-Flash differ
What the numbers mean in practice when choosing between GPT-5 and Qwen-Flash.
-
Qwen-Flash is 98% cheaper on input tokens ($0.022 vs $1.25 per million), which adds up quickly in document-heavy workloads.
-
Qwen-Flash is 98% cheaper on output tokens ($0.216 vs $10 per million) - the bigger factor for tools that generate long documents.
-
Qwen-Flash's 1M tokens context window is roughly 2.5x larger than GPT-5's 400K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
GPT-5 has been superseded by GPT-5.1 - for new builds, consider the newer model first.

FAQs
Qwen-Flash is generally cheaper: $0.022 input / $0.216 output per million tokens, versus $1.25 / $10 for GPT-5. Actual cost depends on how many tokens your workload reads and writes.
Qwen-Flash has the larger context window at 1M tokens, compared to 400K tokens for GPT-5. A larger window means the model can consider more text at once - useful for long contracts, codebases, or months of records.
It depends on the job. Compare the pricing, context window, and strengths above against your workload - and remember the choice isn't permanent. In Appaca you can build a tool on GPT-5, test the same tool on Qwen-Flash, and switch at any time without rebuilding anything.
