How Grok 4 and Qwen3-Omni-Flash differ
What the numbers mean in practice when choosing between Grok 4 and Qwen3-Omni-Flash.
-
Qwen3-Omni-Flash is 86% cheaper on input tokens ($0.43 vs $3 per million), which adds up quickly in document-heavy workloads.
-
Qwen3-Omni-Flash is 89% cheaper on output tokens ($1.66 vs $15 per million) - the bigger factor for tools that generate long documents.
-
Grok 4's 256K tokens context window is roughly 3.9x 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: Grok 4 is a text model while Qwen3-Omni-Flash is a multimodal model, so they often complement each other in a workflow rather than compete.
