How GPT-5 Nano and Qwen3-Omni-Flash differ
What the numbers mean in practice when choosing between GPT-5 Nano and Qwen3-Omni-Flash.
-
GPT-5 Nano is 88% cheaper on input tokens ($0.05 vs $0.43 per million), which adds up quickly in document-heavy workloads.
-
GPT-5 Nano is 76% cheaper on output tokens ($0.4 vs $1.66 per million) - the bigger factor for tools that generate long documents.
-
GPT-5 Nano's 400K tokens context window is roughly 6.1x larger than Qwen3-Omni-Flash's 65.5K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
These are different kinds of model: GPT-5 Nano is a text model while Qwen3-Omni-Flash is a multimodal model, so they often complement each other in a workflow rather than compete.
Strengths side by side

FAQs
GPT-5 Nano is generally cheaper: $0.05 input / $0.4 output per million tokens, versus $0.43 / $1.66 for Qwen3-Omni-Flash. Actual cost depends on how many tokens your workload reads and writes.
GPT-5 Nano has the larger context window at 400K tokens, compared to 65.5K tokens for Qwen3-Omni-Flash. 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 Nano, test the same tool on Qwen3-Omni-Flash, and switch at any time without rebuilding anything.
