Visual understanding models

​

Image and video understanding

Start with qwen3.8-max — Qwen's most capable flagship model, 1M context, 2-hour video support, and the full feature set including function calling and built-in tools. Once your use case works well, try qwen3.7-plus or qwen3.8-flash to reduce cost — near-flagship quality with the same context and features.

​

Image resolution

Most models support up to 16M pixels per image. Higher resolution costs more tokens: each image uses h × w / (32 × 32) + 2 tokens.

​

Video support

• Up to 2 hours / 2GB → qwen3.8-max, qwen3.8-max-0902, qwen3.8-flash, qwen3.8-omni-flash, qwen3.7-plus, qwen3.7-flash, qwen3.6-plus, qwen3.6-flash, qwen3.5-plus, qwen3.5-flash
• Up to 1 hour / 2GB → qwen3.5-omni-plus, qwen3.5-omni-flash (also accepts audio — see Speech models)

To understand sound in a video or provide audio input, use qwen3.8-omni-flash, which produces text output. See Qwen3.8-Omni-Flash for invocation examples.

​
