How GPT-4.1 Nano and Qwen3-Omni-Flash-Realtime differ
What the numbers mean in practice when choosing between GPT-4.1 Nano and Qwen3-Omni-Flash-Realtime.
-
GPT-4.1 Nano is 81% cheaper on input tokens ($0.1 vs $0.52 per million), which adds up quickly in document-heavy workloads.
-
GPT-4.1 Nano is 80% cheaper on output tokens ($0.4 vs $1.99 per million) - the bigger factor for tools that generate long documents.
-
GPT-4.1 Nano's 1.05M tokens context window is roughly 16.0x larger than Qwen3-Omni-Flash-Realtime's 65.5K tokens, so it can work across bigger codebases, contracts, or archives in one pass.
-
These are different kinds of model: GPT-4.1 Nano is a text model while Qwen3-Omni-Flash-Realtime is a multimodal model, so they often complement each other in a workflow rather than compete.
-
GPT-4.1 Nano has been superseded by GPT-5 Mini - for new builds, consider the newer model first.
