How o3 and Qwen3-Omni-Flash differ
What the numbers mean in practice when choosing between o3 and Qwen3-Omni-Flash.
-
Qwen3-Omni-Flash is 79% cheaper on input tokens ($0.43 vs $2 per million), which adds up quickly in document-heavy workloads.
-
Qwen3-Omni-Flash is 79% cheaper on output tokens ($1.66 vs $8 per million) - the bigger factor for tools that generate long documents.
-
o3's 200K tokens context window is roughly 3.1x 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: o3 is a text model while Qwen3-Omni-Flash is a multimodal model, so they often complement each other in a workflow rather than compete.
